The origination of the radon project: • Samsung Solve for Tomorrow Contest: Raise student interest in STEM subjects nationwide through innovative programs with our partners that will help us all build a better tomorrow. 1. Describe an important issue in your school’s community today. Explain how you could apply STEM to address the above issue What is the biggest hurdle your students face that hinders their academic achievement?

Connect to the STEM subjects Connect with community partners Impact the local community Central Ideas Engage 91 High School Students Student centered Complete with a budget of $0

THE RADON PROJECT • STEP 1: Initial Questions: 1) What is radon? • After 2) Why should I care? quick background research we started with a brainstorm session: In 30 seconds or less, what is the most important information someone who knew nothing about radon would need to learn? What would someone who was testing their house need to know/learn?

Starting the project (for each class): Brainstorm Essential Questions and research in small groups. Guest Speaker – Bonnie Rouse - DEQ Compile info into two info sheets One for homeowners – One for the public

Morgan What is it? Where does it come from? What about the radon health mines? Can I prevent it? Is it bad for human health? Radon How do you test for it? Just some of the questions! Are there laws or regulations about radon? What should I do if my house tests high? Are public buildings tested? (Schools) Why do radon levels fluctuate?

We did the background research ……. now what? Emily and Clarice BRAINSTORM: How will we get information to the public? Radio News stations Airplane sign Info booths at games, fairs, etc. Flyer Newspaper Hang signs where “old people go” PSA School Newspaper T-shirts Stickers Car Signs Youtube – rap School Website Facebook Snapchat Twitter Helena Classifieds

Community Partners: DEQ AAA Airchek, Kansas State Radon Program • 100 test kits • Guest speaker (THANKS BONNIE!) • Expert input! (THANKS JOHN and BONNIE) • $200 for test kits • Help with project PR • Discount test kits • Supplied information, ideas, and support for the project

How should test kits be distributed? Facebook? Radio/TV ad? Earth day/Home owner shows? Schedule a pickup at CHS? DEQ reported that only a small % of test kits were returned with a higher rate of return from people who requested them.

Organizing 91 students for a project has it’s challenges…. . • It also has it’s perks!!!! Each student was responsible for 1 test kit. (DEQ kits that had prepaid postage). 79 test kits are out (we have results for about 25) Test kits that are not used will be returned • With parental permission, students could design an experiment and opt to run multiple test kits in their homes. All 50 experimental test kits have been distributed with about 45 results returned

Initial Results • Initial test results (n=31) 55% of homes above 4. 0 p. Ci/L County data = 49% 59% of homes without reported Radon Level (p. Ci/L)of 31 Residences in Lewis and Clark mitigation) systems County 50 High = 49. 0 p. Ci/L Radon Level (p. Ci/L) Average = 8. 6 p. Ci/L County data = 7. 9 p. Ci/L 45 40 35 30 25 20 15 4. 4 p.

Questions: Rebekah What are the impacts of disturbed sites on radon? (Fill, etc. ) How do other states compare to Montana? Why? How is radon level connected to rock type/geologic formations Is there a connection between age of the house and radon level? Questions Can anything else affect radon levels? Ex) Fans on metallic dust, construction Do dry areas produce different results that wetlands? Suggestions on how to spread info? Many of the answers aren’t found online for easy access. Is there a connection between type of foundation, etc. and radon level?

What we would improve/do differently next time: • Check out test kits to students and have them return the kits to me! • Possibly have students work in smaller groups to brainstorm and complete background research • Complete with a smaller number of students (or have students working on multiple projects). • Time the project differently. We had semester tests, State of Montana Testing, registration, etc. that broke the project into parts

What was AWESOME! • Most data from students are not shared outside the classroom. This project can make a difference on and individual to state level! • Students designed and develop ideas. Great for thinking and asking questions. Students are not given the opportunity to develop and take charge of their own projects (and really struggled at project management!!!). • Real-world connections – students can make a difference! • At least 2 families are mitigating their homes

Now What? ? Data Collection Extension Community Outreach Other Ideas? ? ? • Analyze Data • Develop and test hypotheses • Map and GIS? • Earth Day Booth? ? ? • Connect with Lewis and Clark County to share results • Newspaper • Television

Student radon questions: (Grant and Marie) • Are there any guidelines for publicly used buildings? Do tests occur in schools, office buildings, airports etc? If not, why aren’t there any tests occurring? • Schools, for example, require students to attend school for an average of six to seven hours. What about tests there? Have there been any studies on how radon has affected people who have stayed in a largely populated buildings with a higher radon levels as part of their job? Ex: office buildings, schools, government buildings etc. • What is the basis for the EPA action level of four in the U. S. ? • Others?
