Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this activity, learners construct drawing machines using a cup, some markers, and a cricket to control the movement. A programmed LEGO RCX or Cricket is required for this high-tech version.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this activity, learners make a flip book that shows the progression of two solar events on reversible sides of the flip book.

In this activity, learners create a hearing based memory game that they can share with friends.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity, learners use pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.

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 activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.

In this project, students explore how levers work, by making a puppet with moving limbs.
