In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

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

In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this activity, learners observe fly behavior and then build a flytrap.

April showers bring May flowers, but what do coastal storms bring?

In this activity, learners explore sound by constructing their very own banjo out of a coffee can. Learners experiment with the canjo to change the instrument's pitch and timbre.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

In this activity about depth perception, learners create an optical illusion in a shoe box.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

In this activity, learners take apart a used zinc-carbon dry cell battery.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity, learners explore the "nuts and bolts" of gene chips.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.
