Science is Fun - an Introduction to Science

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

Safety in Science

Soap Snake Demonstration• What did you see?

• Did you hear anything?

WASN’T IT AWESOME!

Spontaneous Ignition

Measuring Volume

Measuring Scales-some practice examples

Dropper Bottle

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.

WARNING• DO NOT EAT OR LET LITTLE BROTHERS AND

SISTERS OR PETS EAT YOUR SLIME. IT WILL MAKE THEM SICK• WASH YOUR HANDS AFTER YOU PLAY WITH IT• IT WILL LAST LONGER KEPT IN THE SEALED

BAG

HAVE FUN
