Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this physics activity, learners will explore buoyancy.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity learners will be creating art using a traditional Japanese art style.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this card-based personal choice activity, learners review and sort COVID-19 and vaccine science information.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
