Great Science Share

Good morning! Today is Science Day and we would like you to have a go at some scientific investigations. Try this colourful skittles experiment!

WHAT YOU NEED

A plate or container – preferably white

Skittles, other coated sweets work too

Water

INSTRUCTIONS

Place your skittles or sweets into a white container, try to alternate the colours.

Carefully pour water into the container, if the skittles move, just push them back into place quickly.

Watch what happens

WHY DO THE COLOURS SPREAD?

Skittles are coated in food colouring and sugar. When you pour water over the skittles the coloured coating dissolves spreading through the water.

The colour and sugar dissolve into the water and then diffuse through the water, making it the colour of the skittle.

Can you time how long the colours take to reach the centre of the plate using cold and warm water or even milk? Which do you think will be faster?

Try using other sweets, can you find any that work as well as skittles?

Don’t forget to tell us how your experiment worked! You can use the class email or tell us in the comments below.

Have fun!
