Billy is a mad scientist. This experiment used milk (which is made up of water), detergent and food colouring.
To create a marbling artwork students added a special ink to water and gently swirled the mixture around with a paint brush. A piece of cartridge paper was placed on top. Students counted to 10 and carefully lifted the paper. Then the ‘Magic’ happened as a beautiful marbling pattern appeared on the paper.
Tomas is demonstrating the glass of water experiment. The challenge was to turn a glass of water upside down without the water spilling out? Tomas did this by first filling a glass with water. He then covered the glass with a piece of thick cardboard. Carefully, he held the cardboard and tipped the glass upside down, then let go of the cardboard. Like all good scientists, he observed what happened.
One of the students favourite experiments was called Grow a Rainbow. Have a go at this experiment at home. Follow the instructions carefully. Leave the experiment to sit overnight. What do you observe the following day?
Students learned about the water cycle and used scientific words to describe the different parts of the cycle. Water ‘evaporates’ from the lakes and seas. It becomes ‘condensation’ and fills the clouds up with water. When the clouds are full and can’t hold any more water, ‘precipitation’ occurs. The rain ‘accumulates’ back into our lakes and seas.
Emilia said, The sun heats up the water in the seas and the lake. The water goes up to the clouds. Then it turns into condensation. Then precipitation is when it rains. It goes into valleys and gullies and into rivers. It goes back into the ocean and the lake. Some of the water turns into run-off and goes into the ground.
