This week is Science Week, so we made a lava lamp.
We used pure vegetable oil, red and blue food colouring, water and Alka-Seltzer tablets. First, we put in a little bit of water into a plastic bottle. Then we filled the rest of it up with vegetable oil, almost to the top. The water and vegetable oil doesn't mix so the vegetable oil sits on top of the water, making two layers.
The next step was to put drops of red/ blue food colouring into the bottle and wait until they all sank to the bottom and rested in the water. Now the fun part! We dropped in half an Alka-Seltzer tablet, put the lid on. It looked like a volcano had erupted. The reason it made an eruption was because a chemical reaction to happened making the red and blue food colouring burst to the top. The gas in the Alka-Seltzer tablets reacts to the water and the gas that is produced wants to escape. The little gas bubbles push up through the water and oil, taking some of the food colouring with it.
We turned the classroom lights off and tried it again. We put a torch underneath the bottle and it lit up like a real lava lamp.
We left it over night to settle and we when we came back into school the vegetable oil was separated from the water again.
We had great fun talking about science and becoming scientists this week.
We made a lego man parachute. The children looked at parachutes first and explored what materials they would need to make their group parachutes. The children experimented with different sizes of parachute canopy and lengths of the string. It was great fun watching our lego men and women being released.
The aim of this art activity was to help the children reveal the fascinating, dynamic people they are behind their masks, making an uncomfortable experience for some (especially younger kids), a lot more fun and a lot more normalised.
