Science Week 2026 - 3rd and 4th Class

We had great fun celebrating Science Week 2026 in 3rd and 4th class. This year's theme was water.

We started with the Walking Water experiment. We connected cups of coloured water using kitchen roll and guessed what might happen. We were amazed to see the water slowly travel up the kitchen roll and into the next cup! We learned that this is called capillary action, which is when water moves through tiny spaces in a material, even against gravity.

Then we investigated which materials would make the best damp-proof course for a house. We used sugar cubes to represent the walls of a house and tested different materials to see which would stop water from rising up through them.

We made predictions, tested our ideas and observed the results. We learned why having a waterproof barrier is so important for keeping buildings dry.

We finished the week with a fun challenge. We added soap to water and tried to make bubbles inside a bubble!
