In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.

In this water activity, learners discover ways to move water across the water table.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.
