BHS Cardboard Boat Regatta
Funded Feb 19, 2024Thank you for your generous and wonderful donations! The duct tape is easily the costliest part of this project and you helped us pull through! Our students had a wonderful time building boats from cardboard, sealing it with duct tape, and paddling it across our pool in a very exciting and fun race! Our students loved the experience, and learned a lot during their time building boats. They learned more physics (buoyancy), material science, and engineering skills. They expressed their creativity with some very nice themes! They couldn't be happier with their result after putting in weeks of work. So thank you once again for all your help in making this project a reality!”

Light Bending
Funded Apr 17, 2022Thank you for your wonderful contributions in helping me acquire these additional laser refraction tanks for students to learn about refraction and Snell's Law! These were extremely helpful as I ran into some containment issues with the previous order (leaky tanks). My students were very intrigued and curious when they saw that there was a laser! No eyes were harmed in this experiment! In this activity, students used the refraction tanks to find the index of refraction of various materials such as corn oil, diluted glucose (this one was weird because the glucose clumped up), and water. They shone the laser from both above and below the the liquids to see which way the light bends, and were able to calculate the index of refraction of the liquids! Next step, students will use the refraction tanks to study the phenomenon of total internal reflection by watching what happens if you increased the angle while shining the laser through different liquids. Next year, I want to try more experimental mystery liquids for students to measure the refraction to! I want to thank you all again for this wonderful gift that will last for years to come!”

Funded Dec 30, 2021Thank you for your wonderful contributions in helping me acquire these laser refraction tanks for students to learn about refraction and Snell's Law! My students were very intrigued and curious when they saw that there was a laser! In this activity, students used the refraction tanks to find the index of refraction of various materials such as coil oil, diluted glucose (this one was weird because the glucose clumped up), and water. They shone the laser from both above and below the the liquids to see which way the light bends, and were able to calculate the index of refraction of the liquids!
