Today, we did a science experiment called ‘Walking Water’. We proceeded with the experiment by filling two glasses with water while leaving the third glass empty.
The children then all took turns to put drops of blue food colouring in the first glass of water and then red food colouring into second glass of water.
After that, we used the paper towels and made it into a long strip. We then placed one end into the blue coloured water while the middle part of the strip was positioned at the bottom of the red coloured glass. Next we placed the other end of the strip at the bottom of the empty glass to see the change in colour. We left this experiment out for a few days to see the changes. The children noticed that the empty glass was filing up with purple coloured water.
Through this science experiment, the children learnt that water is a liquid so when you put a paper towel into the water, it absorbs the water. The children understood that the coloured water travelled up the paper towel and started to drip into the empty glass which is why this experiment is called ‘walking water’.
The children really enjoyed this science experiment as they were able to see the change in colour. The children understood the process and were able to explain it during circle time.
