Squidgy Slime
Source Institutions
In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
Periscope
Source Institutions
In this optics activity, learners build a spy tool to secretly view things over walls or around corners.
Friction Racing
Source Institutions
In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.
Can Car
Source Institutions
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.
Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.
Slime
Source Institutions
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.
Bearings for Your Whirligig
Source Institutions
Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.
Build a Roller Coaster
Source Institutions
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.
Scytale Messages
Source Institutions
In this activity, learners use a soda can to decode a secret message. Learners wrap scytale (pronounced ski-tally) code around a can and challenge friends to see if they can crack the codes.
Flubber: Make a polymer!
Source Institutions
This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.
