Sci Fri Science Club: Freeze Challenge
We challenge you to create something totally new, and totally frozen.
Model Eclipses
Model solar and lunar eclipses by making your own physical, proportional representations of the Earth and Moon.
What Do Cochlear Implants And Hearing Aids Sound Like?
Learn how hearing aids work, then conduct your own test to determine whether hearing aids can improve speech recognition for cochlear implant users.
Make a Kite With Physics
Build a delta kite and explore some of the forces involved in flight. Challenge your design skills to improve your kite’s stability in the air.
Build An Ultra High-Speed Toy Out Of Paper
Make a paper toy that spins thousands of times per minute, and then measure, and try to modify, its speed.
Design a Better Vortex Cannon
Build an air vortex cannon that shoots air across the room, then modify and test your design to make an air cannon that shoots even farther.
High Pressure in the Deep Ocean
Pressure is a huge challenge for deep ocean explorers. Learn how pressure changes with depth and explore its effects on compressible solids in this series of experiments, demonstrations, and real-life data collected aboard the E/V Nautilus.
Build A Cloud Chamber
Observe the radioactive particles all around you by building a cloud chamber using a clear container, dry ice, and a little rubbing alcohol.
Solar Convection
Use hot and cold water to see how fluids at different temperatures move around in convection currents in this DIY Sun Science Activity from Lawrence Hall of Science.
Map Sun Trails
Use photosensitive paper to make a map of the path of sunlight on the earth in this activity from the Lawrence Hall of Science.
