Learners explore the physical properties of a variety of balls and how they bounce. The point of the activity is not necessarily to have students arrive at a precise explanation for the phenomena...

In this activity, learners create painting machines that can paint moving forwards and backwards. Learners construct the machines out of LEGOs, motors, a programmable PICO Cricket, and a cardboard...

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket. As learners move the wands around, they expose the...

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room. Learners follow the engineering design process to design and build a rover out of...

In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects. Learners will...

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus. Learners roll...

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions. This activity can be combined with other activities to create...

In this activity, learners make a Benham Top to explore visual illusions and optics. This activity guide includes three different instructions for making the spinner using various recycled...
