My child participated in an experiment with 6 glasses, each containing a small amount of water with different food colouring added. He joined them using paper towels to observe how the colour travelled up and then mixed.

Science

• The student learned about the concept of absorption as they observed the movement of water and food coloring up the paper towels.
• They discovered the concept of capillary action as they noticed the water traveling against gravity through the paper towels due to cohesion and adhesion forces.
• They observed color mixing and learned about the concept of diffusion as the different food colorings mixed together in the water.
• They also developed an understanding of the properties of liquids and how they interact with each other.

Encourage the child to extend their learning by conducting similar experiments using different liquids such as oil or vinegar and observing how they move and mix. Additionally, they can try using different materials to connect the glasses to see how it affects the movement of liquids.
