Make Your Own Slime
This is a Steve Spangler mixture. We order the Slime Goo and the Cross Linking Solution and the Cups. Scientists can take home their slime in the sealed cup.
Scientists wrote secret messages with a special Ammonia
Water solution. We also used a GoldenRod paper and talked
about the chemistry behind this experiment.
The Crystal Bubble is a favorite. We add dry ice to a large bucket of water. The dry ice creates a gas and the scientists make a giant ring around the top of the bucket to form a bubble film. Instant large bubble!
Screaming Balloons consist of a hex nut and a balloon. Students compare the sound of a hex nut inside the balloon to the sound of a penny. Sound Tubes make different pitches of sound as you twirl them.
Grow Your Own Body Parts
You have all seen these in one form or another. Growing alligators, growing fish, ..endless examples of hydrophillic and hydrophobic polymers. These are especially nice in that we have a hand, nose, brain and ear! Great science behind this activity in that the hydrophillic ingredient in the growing body parts "loves" water and this helps the body part to GROW! The hydrophobic ingredient "doesn't like" water and this helps the body part keep its shape.
