On Friday we asked the question "Can raisins dance?
Here we are making predictions. Most of us thought 'No, raisins cannot dance!"
Mrs Natusch then explained that we would conduct an experiment to see if raisins could dance using fizzy drink.
We used our prior knowledge from a previous experiment and knew that fizzy drink has CO2/carbon dioxide in it and we knew that made it fizz and produced bubbles!
Here are photos of our experiment;
|Raisins in normal water.|
We found out that raisins in water sink to the bottom because raisins are more dense than water, therefore they sink.
|Adding raisins to fizzy drink.|
|Comparing raisins in normal water and fizzy drink.|
Watch our experiment in action.....
Here is a video explaining how raisins dance; starring Leah and Thomas, produced by Zaric.
This is their first attempt at explaining our experiment Do you have any questions for them, is there anything that you need clarified or perhaps you would like to just leave them a comment?
