24 November experiment number 2

Experiment number two was 'elephant toothpaste'.  This required lots of different materials to create and everyone was pretty excited to try something new and see what happened.  We mixed everything together but we were expecting it do show more of a reaction.  We talked about what changes we would make next time. We shared things such as adding less water, leave the lid on to build up pressure, have more yeast, more hydrogen poroxide and to shake it up more.  We think it might be a good idea to try elephant toothpaste again 😊

24 November Experiment number 1

Today we tried two new experiments. Our first one was Coke and mentos.  We discussed what might happen when the mentos is placed in the Coke and and we had to explain our reasons.  Alex made an interesting suggestion that the mentos had to be rough for it to react with the Coke better.  We went outside and tried the mentos with a small and large bottle of Coke, we tried smooth and rough mentos too.  We didn't notice a big difference.  We discussed more about what we noticed and why it may have happened.  Check out the pictures.

Science 17 November

Today we hoped into 3 groups and did our own science experiments.

Our Focus was to think, notice and wonder what might happen if...

Group one made Rainbow paper - we used black paper, clear nail varnish and a bowl of water.
It works by dipping the paper into the water which has the nail polish in it.  The nail polish then makes a thin layer on the paper and the light gets reflected by the nail polish creating rainbow patters.

Group two made a rain cloud - we used shaving cream, water, food colouring and clear plastic cups.  We discussed our prior knowledge about how rain clouds are made and why it rains.  During the experiment we noticed that the more food colouring we used the heavier it rained and the less food colouring we used the less it rained. 

Group 3 made Bubble chain - we used a coke bottle cut in half, dish cloth and water with dishwashing liquid in it. We placed the cloth over the end of the bottle, dipped it into the soapy water and then blew.  All the bubbles came out and never separated this is because the air struggles to get through the cloth and then the air can't get between them and to separate the bubbles.
