Kindergarten Activity No 61 – Walking Water

Walking Water Experiment

The walking water experiment is a science experiment that will introduce children to colour mixing.  From this experiment the children will learn what happens when you mix primary colours together. They will be amazed watching how the water, absorbed by the kitchen paper towels, travels to the empty cup, and fills it with coloured water.

 

For this experiment you will need:

• 3 transparent glass cups (It is important that the cups are of the same height)
• Food colouring (red, blue, and yellow)
• Some pieces of kitchen paper towels / kitchen roll
• Water

 

How to do this experiment:

1. Put the 3 cups of the same height next to each other.
2. Encourage your child to fill the cups with water (they should be about 3 quarters full), leaving the cup in the middle empty.
3. Choose two colours of food colouring and add some drops to the water. You can mix :red + blue, yellow + red. yellow + blue,
4. Before adding the kitchen towel to the cups say the colours.
5. Fold some paper towels vertically in half, and then fold in half again.
6. Put one end of the paper towel in the water and the other end in the empty cup. (As indicated in the picture).

 

 

7. Watch the paper towel absorbing the coloured water and filling the empty cup.

8. At this point you can ask your child:

 

• “What do you think is happening?”
• “What do you think is going to happen?”
• “What colour do you think the water will be?”

9. Leave some time and watch how much coloured water from the two cups has travelled to the empty cup in the middle.

 

 

Make a record sheet and record your results:

1.    yellow + blue = __________
2.    red + blue     = __________
3.    yellow + red = __________
