In this physics activity (page 6 of the PDF), learners will try to keep a marble in a bottomless cup without touching the marble inside.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.

In this activity, young learners will describe objects by their properties and sort by color, weight and texture. This activity uses household items and toys for materials.

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

In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.
