We decided it would be pretty fun to do some science experiments.
So, what did we discover?? Well, we discovered that sometimes science experiments just do not work, even when you read and follow the instructions perfectly.
The first experiment we did was the 'Dancing Raisins'. We popped raisins into a cup full of soda water and patiently waiting for the raisins to start dancing.
We noticed that the bubbles in the soda water attached themselves to the rough surface of the raisin and pulled it up to the top. When they got to the top the bubbles popped and the raisin went back down.

Magic Lava Lamps...
Our second experiment was the magic lava lamp trick. This experiment took lots of trial and error - something we discovered you need in science. Alongside trying things out you need to be able to make lots of predictions too! We were all really good at sharing our ideas an thinking about what might happen.
Next we added some food colouring, the foot colouring sank to the bottom of the cup although a little bit mixed with the water and the water changed colour.
Then we added and effervescent tablet which was supposed to fizz and cause a lava lamp reaction - sadly this did NOT happen. We did some thinking on our feet and talked about how bicarbonate of soda makes a volcano fizz (we remember doing that in the sandpit earlier this year) so we sent Colleen running over to the kitchen to find some bicarbonate of soda.
We added one teaspoon of bicarbonate of soda into each cup. It did the weirdest thing - it made structures that looked like clouds before making the food colouring bubble and it did look a bit like a lava lamp. Phew! What a lot of brain work!
Thank you Year 3 for a fabulous week of work with us in Mt Peel.
