Science is Fun
Learning Intention:-To become interested in ScienceTo make scientific observationsTo become familiar with safety in ScienceTo safely conduct a simple experiment
Success Criteria:-- I can use my senses to observe interesting
Science demonstrations- I can apply safety rules and use safety
equipment to perform an experiment- I can make Slime
WHAT IS SCIENCE?
Getting Knowledge Ready
Hands up any one who has never done any science before!
Observations in Science
We need to use our senses
RED ALERTWE NEVER TASTE OR TAKE A BIG WHIFF OF ANYTHING IN THE SCIENCE LABORATORY
WE USE THE WAFTING TECHNIQUE TO SMELL STUFF

Making Slime
1. Collect a lab coat and safety glasses2. At your station you will find :- a plastic cup a paddle pop stick a 100ml measuring cylinder
a 10ml measuring cylinder borax solution PVA solution
Food dye sealable bag marking pen3. Measure out 30ml PVA solution4. Measure out 5ml Borax solution5. Add these two solutions to the plastic cup with 2 drops of food dye6. Very, very gently mix together using the paddle pop stick. Once it
starts to get thick (congeal) mix faster, until you have your SLIME.7. Play with it. Place it in the sealable bag to take home.8. Label the bag ‘Slime’ so people know what is in the bag.
