On Wednesday we carried out two more experiments - the Skittles science experiment and the paper towel colour mixing science experiment! We wrote the experiments into our copies and then carried them out.
We had great fun observing and taking part in these experiments - take a look at the pictures to see the outcome!
Paper Towel Colour Mixing
You will need:
Water Kitchen roll Plastic glasses
Food colouring in primary colours
Method:
1. Put red food colouring into one glass
and blue food colouring into another
glass. Add water to both glasses.
2. Using 1-2 sheets of kitchen roll, roll
length ways into a tube.
3. Bend in half and dip one end into each
glass.
4. Watch what happens as the colours
travel!
The Science behind it.
Water moves up the paper towel because the paper is absorbent, it sucks up
water. The colour travels with the water making the paper change from white
to red or blue. Colours mix when they are joined together, red and blue make
purple. See what colours can be made with just the primary colours.
