Science Performances
|
Physical Reactions: |
Vortex – Water Tornado |
Atmospheric Pressure – Hard-boiled egg on top and then in a bottle |
Liquid Nitrogen (-320F) demo – the freezing of a super bouncing ball, a rubber band and a banana ( to use as a hammer) |
Three states of Matter: Solid, liquid and gas. Solid carbon dioxide (dry ice, -108F), sublimation demonstration |
Test all 5 Senses – using a cup of orange juice |
Chemical Reactions: |
Oxidation-Reduction – disappearing red sugar solution |
Halloween colors – a clear solution turns orange then black, if i blow through it? |
Phenolphthalein Reaction – a clear solution turns red then back to clear when poured from a pitcher in to a class. PH test, acid/base |
Chemiluminescence – combining & mixing solutions that glow in the dark, if room is dark |
Special Demonstrations: |
Controlled Fire& Explosion – (school policies may not allow this demonstration) |
Special Ice Cream Demo – I make real edible ice cream using house hold ingredients |
Not all of the experiments listed may be performed due to time limits. If time allows a question/answer session can be held, ‘ask the scientist’. |
