Kim, a 12th grade student at West Lafayette High School, discovered his dog, Joy, had heartworm disease and ordered medicine through an online pharmacy.

But the medicine Kim ordered would not only be ineffective but also aggravate Joy’s illness even more.

Motivated by his dog’s health scare, Kim designed a way for people to verify the authenticity of pharmaceutical products — by printing an edible QR code directly on the medicine.

Kim was one of in middle and high school who presented their inventions and research projects focused on solving key global issues at the in Washington, DC.  

“There have been countless tragedies and deaths caused by either substandard, falsified or diverted pharmaceutical products,” Kim told ĂŰĚŇÓ°ĘÓ. “So I’m glad to have had this opportunity to raise more awareness of counterfeit medicine.”

Hosted by and the , student innovators were selected from an array of nationwide competitions, including the where more than 2,500 students submitted projects across six categories: Environmental Stewardship, Future Foods, Health & Medicine, Powering the Planet, Tech for Good and Space Innovation.

Here are five student innovators featured at the National STEM Festival:

Joshua Kim, 18

West Lafayette High School ¡ West Lafayette, Indiana

Among more than 50,000 online pharmacies worldwide, Kim found only 3 percent operate and distribute medicine legally — contributing to the annual deaths of over one million people.

Kim said the measures most pharmacies use to reduce counterfeit concerns are “limited by low security,” such as only tracking medicine through its exterior packaging.

“It’s easy for medicine to be removed from their packaging…and dose level securities are either limited by the need for expensive technology or trained personnel,” Kim said.

“So this means patients at home do not have access to ways of verifying their medicine.”

Kim believes his edible QR code will allow people to ensure they are receiving genuine and legitimate medicine.

Ashley Valencia, 17

Harvest Preparatory Academy ¡ Yuma, Arizona

Self-conscious about her crooked teeth, Arizona high schooler Ashley Valencia saw how expensive dental care can be growing up in a low-income family. But it wasn’t just her family that couldn’t afford dental care — many of her neighbors also struggled to afford it. 

Valencia, a 12th grade student at Harvest Preparatory Academy, channeled her insecurity to help students in developing countries who have even less access to proper oral hygiene products — by creating an affordable toothpaste and mouthwash using their native plants.

“I always knew I wanted to do something in medicine so when I thought about different [research] topics close to me, I started to think about my past experiences,” Valencia told ĂŰĚŇÓ°ĘÓ.

“That’s why I created my own oral treatments that were easily accessible and affordable to people who might not have access to the things I had,” she added.

Valencia said she shared her research with public schools in the Philippines to address their students’ dental concerns.

At the festival, Valencia said she plans to travel to developing countries across South and Southeast Asia to share her oral hygiene products.

“Because I come from a school that doesn’t have a lot of resources…being able to attend the festival and present my research to all of the important people that were there was really exciting,” Valencia said.

Clarisse Telles Alvares Coelho, 18

New Mexico Military Institute ¡ Roswell, New Mexico

From lion’s mane to king oyster, New Mexico high schooler and longtime vegetarian Clarisse Telles Alvares Coelho loves eating all types of mushrooms.

Coelho, a 12th grade student at the New Mexico Military Institute, said the misconceptions of mushrooms inspired her research project on their health benefits — particularly the abundance of a soluble fiber called beta-glucan.

“I knew many people didn’t like mushrooms…but what if I was able to make them change their minds,” Coelho told ĂŰĚŇÓ°ĘÓ. “With beta-glucan acting in your immune system, our metabolism works faster.”

Coelho said she was “very surprised” to have the opportunity to present her project at the festival.

“It was such a great feeling because there was so much hard work and late nights put into researching this project…[so] it was so amazing to be recognized,” Coelho said.

Alicia Wright, 17

Rockdale Magnet School for Science and Technology ¡ Conyers, Georgia

Concerned by our global carbon footprint, Georgia high schooler Alicia Wright discovered the majority of CO2 emissions come from the cement used in construction.

Wright, an 11th grade student at Rockdale Magnet School for Science and Technology, found a way to replace cement with mycelium — a type of fungi that can be transformed into a biodegradable construction material.

“I was inspired by the complexity of mycelium and how fungus works,” Wright told ĂŰĚŇÓ°ĘÓ. “This will better the environment so that future generations can enjoy as we have.”

At the festival, Wright said the diversity of students presenting their projects with her felt “empowering.”

“It was very encouraging to see people with my skin color and gender presenting with me,” Wright said.

Haasini Mendu, 16

William Mason High School ¡ Mason, Ohio

Ohio high schooler Haasini Mendu came up with a way to improve medication dosage for Parkinson’s disease — a disorder that causes involuntary body movement, often called tremors.

Mendu, an 11th grade student at William Mason High School, designed a wearable device that quantifies the number of tremors someone has and automatically sends the information to an app she created called “TremorSense.”

She said the information is processed through an “AI-based machine learning” filter to distinguish between tremor and non-tremor movements.

Mendu said the opportunity to meet other students and build connections was her favorite part of the festival.

“It was very easy to make some friends and also learn about their very cool inventions and ideas,” Mendu told ĂŰĚŇÓ°ĘÓ.

“Having this recognition…feels motivating to continue working on my skills [because] there were so many people interested in what I’m trying to do with my research.”

There’s one hitch: According to , districts are already spending, or planning to spend, almost a quarter of funds from the American Rescue Plan on facilities and operations.

“Getting clarifications and new restrictions this late in the game is tough on [districts],” said Marguerite Roza, director of the Edunomics Lab at Georgetown University. “What happens if money is already approved and spent before these recent” guidelines were released?

The department was especially pointed about using federal dollars to build and upgrade sports facilities. The school district, for example, paid for new athletic fields and the in Alabama renovated weight rooms

Such expenses would not be allowed unless districts can connect the project to COVID preparedness and response, the document said. “It is unclear, for example, how constructing a swimming pool is related to the pandemic,” according to the department.

The Milwaukee district declined to comment on its use of funds for athletics-related projects, while the Wisconsin Department of Education said it is still reviewing the guidance to “determine next steps.” Alabama officials did not respond to requests for comment.

With billions in COVID relief funds for schools still unspent, school finance experts say the guidance could confuse district leaders who have been waiting for the guidance for months. But with it dropping before the holidays, it could be well into January before states offer webinars or other opportunities to explain it to districts.

The document is not law, but says leaders should be prepared to justify how their projects relate to the pandemic. The has picked up this fall, according to Roza’s tracking of expenditures. A recent survey from , however, showed that over 40% of those responding said they were struggling to navigate compliance standards related to spending the funds. 

In March, the department schools Superintendent Richard Woods that it was OK for districts to use the money to cover rising fuel costs. The new guidance doesn’t specifically address that scenario and only gives expenses “related to improving indoor air quality” as an “acceptable” example. 

Department officials told ĂŰĚŇÓ°ĘÓ that the newest information is consistent with past guidance and that they have always “urged caution around long-term facilities and capital expenditures.” They said whether an expense is allowable is still up to state officials. 

“It really isn’t our role to ensure that states are looking at every single situation in the exact same way because … the context matters,” the official said.

Still, Elleka Yost, director of advocacy for the Association of School Business Officials International, said the “tone” of the document bothers her.

“The quality of school facilities impacts student health, well-being, attendance, engagement and learning,” she said. “Investing funds in facility improvements should be seen as part of a district’s strategy to recover from the pandemic and improve student learning rather than as something contradictory or unessential to achieving those goals.”

Some district leaders have made the case for spending relief funds on athletic facilities by saying they .

Sasha Pudelski, advocacy director for AASA, the School Superintendents Association, that instead of providing flexibility for districts with classroom additions going up or extensive renovations already underway, the department chose to “criticize these decisions and chastise districts for these expenditures.”

The department provided no more details in response to the requests for extensions on spending the funds that came from AASA and , but said it will lay out a process “at a later date.”

Districts worried about obligating the money by the 2024 deadline could pay ahead for services delivered over multiple years; the document lists a software license as an example. But it also warns that this practice is “not good stewardship” of federal funds.

Teachers and parents

Since the American Rescue Plan passed in March 2021, experts like Roza have also cautioned districts against using the funds for teacher and staff pay raises because it would be hard to continue covering those higher costs when the money runs out. 

But the guidance notes that the funds can be used for “permanent salary increases.” Austin Reid, senior legislative director for federal education policy at the National Conference of State Legislatures, finds that advice puzzling, given talk of a .

“Funding full roles or permanent salary increases can still be a risky bet by local districts, especially given the uncertainty in the economy,” he said.

Paying parents incentives to ensure their children go to school, on the other hand, is off the table, according to the department, which called attendance a “mandatory activity.”

“This one frustrated me, in part because we have a massive problem with chronic absenteeism,” Roza said. “Seems like we shouldn’t be invoking the notion that school is mandatory so soon after school became un-mandatory when it shut down for a year.”

The vote came the day after the Senate passed a $1.2 trillion infrastructure bill, which now goes to the House. Speaker Nancy Pelosi has said she won’t introduce the infrastructure package for a vote until she’s assured all 50 Democrats in the Senate are on board with the rest of the party’s agenda regarding social, immigration and climate policies. But to get there she’ll have to balance competing agendas within her own party.

“The House will continue to work with the Senate to ensure that our priorities for the people are included in the final infrastructure and reconciliation packages, in a way that is resilient and will build back better,” Pelosi said in Tuesday.

Moderate Democrats, however, her to take action on the infrastructure bill now and not wait until later this fall when committee leaders in the Senate work out the details of the $3.5 trillion bill. Observers say it could be late fall before the plan passes the Senate.

“After years of waiting, we cannot afford unnecessary delays to finally deliver on a physical infrastructure package,” moderates said in a letter. “As we continue to recover from the pandemic, the American people are counting on us to drive real results for them in every single Congressional district.”

Senate Democrats are using a process called reconciliation that allows them to pass the spending package without any Republican votes.

Sen. Krysten Simena of Arizona, who took the lead on negotiating with Republicans over the infrastructure bill, and Joe Manchin of West Virginia, another moderate Democrat, have suggested the $3.5 trillion figure is .

But Rick Hess, a senior fellow at the conservative American Enterprise Institute, said he doesn’t think most Democrats will be “treating the fiscal implications of budgetary rules with much seriousness.”

Manchin crossed the aisle in a long vote session last night to approve to the budget resolution that opposes allowing federal funds to support the teaching of critical race theory in K-12 schools, such as hiring consultants for teacher training. Sponsored by Arkansas Republican Tom Cotton, the legislation would add to several state laws banning educators from teaching that racism is embedded in U.S. systems to advantage white people.

It’s the larger $3.5 trillion package that concerns most education advocates. In to Congress Monday, 17 leading organizations urged lawmakers to include at least $130 billion in the reconciliation bill for school facilities — a concern that was left out of the infrastructure bill.

“The longstanding neglect of school facilities disproportionately impacts low-income school districts and those districts with particularly aging facilities,” the letter said. “These districts often lack a local tax base that can be leveraged for new school construction, major capital improvements, or building renovations and modernizations.”

School nutrition advocates want to see permanent funding for free school meals beyond the 2021-22 school year. Over 400 organizations have signed saying such a policy “eliminates the cost barrier for families who do not qualify [for free or reduced-price meals], but who still struggle to make ends meet.”

It’s unclear, however, whether Democrats can stretch the $3.5 trillion to cover everything they’d like to deliver, including $200 billion for pre-K, $109 billion for two years of free community college and several teacher education and higher education initiatives. The president’s agenda would also extend an increase in the Child Tax Credit for four more years and include paid family leave.

The U.S. Senate passed the $1.2 trillion infrastructure bill on Tuesday, with 19 Republicans joining 50 Democrats in approving the measure. 

“I want to thank a group of senators, Democrats and Republicans for doing what they told me they would do,” President Joe Biden said. “They said they’re willing to work in a bipartisan manner, and I want to thank them for keeping their word.

The Infrastructure Investment and Jobs Act, the result of a long negotiating process with Republicans, addresses the “clear and present danger” of lead pipes carrying drinking water, reduces transportation costs and increases internet access, Biden said.

“During remote learning during the pandemic last year,” he said, “we saw too many families forced to literally sit in their vehicles in a fast food parking lot so their children can get on the internet they couldn’t afford and didn’t have access to at home.”

The bill — the first phase of Biden’s domestic agenda — now heads to the House, but Speaker Nancy Pelosi isn’t expected to introduce it until it’s clear that all Democrats will support the second, and larger, social spending package.

The U.S. Senate is expected to pass a bi-partisan $1.2 trillion on Tuesday that includes funding for electric school buses, eliminating lead pipes in schools and expanding the nation’s access to broadband.

Most of President Joe Biden’s agenda for education and families, however, is included in a separate $3.5 trillion Senate Democrats unveiled Monday, with plans to pass legislation over Republican opposition.

Progressive House members have been threatening for months that they won’t approve one without the other, setting up a potential drawn-out battle this fall if Democrats don’t get everything they want in the larger “American Family Plan.” Republican leaders, meanwhile, have urged Democrats to separate the two packages to ensure that to fix roads and bridges and expand public transportation, among others, make it to the president’s desk. Thus far, House Speaker Nancy Pelosi the piecemeal approach, showing a determination to pass as much of the president’s agenda as possible within his first year in office.

“I don’t believe leadership would move one [bill] without being confident the other is locked down,” said Julia Martin, legislative director of Brustein and Manasevit, a Washington-based education law firm.

The strategy, she said, is an effort to ensure the larger social spending bill — which includes universal pre-K, free community college and an extension of the Child Tax Credit — would pass despite reservations from moderates over the cost and objections from more liberal members that it doesn’t go far enough.

With Democrats in control of both houses in Congress, they can pursue a process known as reconciliation, which doesn’t require any Republican votes.

“If you’re doing a one-party bill anyway, there’s a lot of pressure to pass long-standing and more liberal priorities,” Martin said.

Some Democrats, for example, want to see the larger Child Tax Credit, which families began receiving last month, . The one-year increase passed as part of the March relief bill, and Biden’s plan extends it through 2025. House and Senate Democrats are also pushing for , but Biden’s proposal doesn’t go that far. He’s calling for free school meals for all students in the , covering about 70 percent of students in the elementary grades.

The chance Democrats could lose more seats in Congress is another reason they’re pushing to pass both packages. With midterm elections next year, some experts expect Republicans to challenge the majority on issues such as .

Democrats “could very likely lose the House in ‘22, so this is the moment,” said Danny Carlson, associate executive director for policy and advocacy at the National Association for Elementary School Principals.

The $3.5 trillion package includes $726 billion for the Senate education committee, which will write bills for pre-K, expanding access to child care, building and renovating schools, and addressing teacher shortages. Senate Majority Leader Chuck Schumer of New York, in a letter Monday, asked the committees to submit their bills by Sept. 15.

He also urged Democrats to “go on the offense” during the upcoming recess “to explain how our budget will lower costs and cut taxes for American families.”

But Republicans argue it will only increase the national debt. In , Senate Minority Leader Mitch McConnell called the package “far-left radicalism” and said on the floor Saturday that budget committee Chairman Bernie Sanders’s “socialist shopping list will make every disagreement we’ve had in landing the infrastructure compromise look like a rounding error.”

Last week, the Congressional Budget Office released showing the infrastructure bill would increase the federal deficit by $256 billion over the next 10 years. That figure the bill, but is fueling objections to additional spending

McConnell specifically mentioned the administration’s child care proposal, calling it “government meddling … that would privilege certain families’ choices over others.’”

Biden’s plan seeks to lower the cost of child care, while still giving parents options, including centers and family child care providers. But some conservatives argue there’s still too much emphasis on group settings.

Katharine Stevens, a resident scholar at the conservative American Enterprise Institute, said while she understands that full-time child care is essential for working parents, “it’s not optimal for the majority of children — even harmful for some — during the most crucial period of development.”

The plan would increase pay for providers, which can allow centers to hire better-qualified teachers, but Stevens said ensuring all programs reach high quality is still “a very big if.”

When Congress returns in the fall, the Senate will also have to take up the fiscal year 2022 budget. The House has already passed seven appropriations bills, including nearly $103 billion for the Department of Education, a $29 billion increase over 2021.

But now, with chicken and beef prices up, a worldwide shortage of packaging materials and a dearth of long-haul truckers, she’s not as sure what she’ll be serving the district’s 18,000 students this fall. And she won’t be surprised if distributors start adding transportation surcharges “to stop the bleeding on their end” — something she hasn’t seen since the Great Recession.

“It’s a domino effect,” she said. “We’re at the point now where we don’t even know what’s going to come in the back door.”

Food services are just one aspect of school operations affected by inflation, which is experiencing a 13-year high. Wages are climbing because districts can’t find enough employees to drive buses or provide students additional academic support. Price hikes on materials are causing some districts to hit pause on construction projects and districts are for teachers to help students catch up.

At a time when the American Rescue Plan is flooding school districts with more federal money than they’ve ever had, educators are slowly awakening to the reality that those funds might not go as far as expected and that inflation may have a lasting impact on their regular budgets as well .

“School districts are like little cities. You’ve got food service. You’ve got transportation. You’ve got maintenance. Inflation across the sectors will impact all those areas,” said Charles Carpenter, chief financial officer for the Denver Public Schools.

The economic indicators are clear. This summer, the Consumer Price Index — which measures changes in what people typically pay for goods and services — saw its largest one-month and 12-month increases since 2008, according to the government’s .

Experts attribute in inflation in part to the rollback of pandemic restrictions: Consumers are traveling, eating out and shopping more, which is driving up prices. But there’s not enough supply to meet the demand.

The debate is over how much to worry about it. Some that President Joe Biden’s policies — the partisan relief bill that passed in March and his big-ticket infrastructure packages — will hurt the economy, while others argue this period of inflation and won’t spiral out of control.

Either way, Carpenter is closely monitoring costs of raw materials like lumber and copper as the district moves forward with building new schools and adding air-conditioning to 24 sites over the next three years.

Contractors “are bidding on our projects knowing that they’ll see price increases,” he said. “Do you try and push forward now and lock in a price or wait and it could be worse?”

Some districts are discussing whether to to lower prices and others have decided to pause projects because contractors can’t provide solid cost estimates. The St. Clair R-III School District, southwest of St. Louis, decided in June to delay construction on a performing arts center and a bus facility until costs stabilize. “It has become much more difficult to obtain competitive, cost-effective bids for construction projects,” Superintendent Kyle Kruse said in his report to the board.

‘Can’t find the people’

While districts might be able to defer construction or renovation, they can’t put off addressing students’ academic needs — especially given the extreme learning loss that often accompanied more than a year of remote learning.

“We’ve got this short-term demand for services to mitigate instructional loss and a shortage of labor willing to put in that time,” said Jonathan Travers, who leads consulting services for Education Resource Strategies, a nonprofit that helps districts leverage resources to improve student learning.

That’s why in addition to price hikes on materials, districts are seeing higher labor costs. Some have offered bonuses and even to attract summer school teachers. The danger for districts, he said, is that unions might expect to maintain those higher wages when they return to the bargaining table to negotiate future contracts.

In Plymouth-Canton, Hennessey still has 20 positions to fill before fall. She said entry-level school nutrition employees earn about $11 per hour, but that doesn’t come close to the $15 they can earn at McDonald’s. And districts nationally are struggling to find even with higher pay.

“It’s great to have all this money,” said Uri Monson, chief financial officer with the Philadelphia schools. “But if you can’t find the people to do the work — even if you’re going to pay them — that’s a problem.”

Districts aren’t the only ones feeling the pinch. from the accounting firm KPMGshowed parents estimate they’ll spend an average of $20 more on school supplies this fall. Parents of young children, many of whom delayed enrollment last year, anticipate spending $156 per child — a 32 percent increase over last school year.

What’s eating up much of their back-to-school spending? — a necessity some may have skipped last fall when many districts opened remotely.

One relief for families is that the increased costs come at the same time the majority of households with school-age children are receiving monthly of $250 to $300, approved as part of the relief bill.

‘Calm the markets’

Some districts plan budgets to allow them to ride out periods like this. The Philadelphia district signs fixed contracts for expenses such as fuel, food services — and, of course, labor.

“We occasionally get criticized when we do long-term guaranteed pricing contracts,” Monson said. “No one is going to complain right now. This is exactly why we do it.”

But he acknowledged that the soaring prices are hitting contractors hard as well as those waiting for supplies. “The cost of wood and basic materials has been out of control,” Monson said. And with shipping delays, he’s urging departments to allow longer lead times for deliveries. “It’s really hard to order something on Friday and expect it to be there on Monday.”

That’s because the most Americans experienced at the beginning of the pandemic haven’t really gone away.

“There are shipments from Asia that have been stuck at the Los Angeles port since October” — mostly because of labor shortages, said Charlie Andrews, a senior cost manager with Rider Levett Bucknall, which advises school districts on construction costs and provides project management services.

When contractors face unforeseen costs, such as tariffs, they often pass those on to school systems.

Mary Filardo, executive director of the 21st Century School Fund — which advocates for modernizing school facilities — said cost fluctuations help make the case for Biden’s $100 school construction plan, a combination of direct grants and bonds. The proposal didn’t make it in the with Republicans, but is expected to re-emerge in the details of a Democrats have proposed.

“Districts need long money,” Filardo said. “It will calm the markets somewhat and give them more leverage as they plan and implement projects.”
