Today room 4 were scientists and completed a raisin experiment using sparkling water, tap water and raisins. We found out that raisins sunk to the bottom in tap water and only had a little number of bubbles on them. In sparkling water we found out that the raisins danced up, down and around! This was because the carbon dioxide created lots of little bubbles that stuck to each raisin, pushing the raisin up and down. It was a fun filled afternoon with lots of learning and laughter.

Room 4 made sherbet! As part of our experiment the children had to taste each ingredient seperately which was an interesting and exciting process. We then mixed all ingredients together and made the sherbet! During the experiment the students were being scientists by making predictions and recording their observations.

Lots of students have even bringing in interesting and exciting news items. Today Theo bought in a crystal collection, the children loved looking at all the different types of crystals. And Summer bought in a piece of carved wood that she got as a present when she was 5!

Today the children completed a yeast in bags science experiment. The students had 4 bags with different ingredients in them, cold water, cold water and sugar, warm water and warm water and sugar and each bag had 1 tablespoon of yeast. It was interesting to predict what would happen and observe what actually happened. The children found that the bag with warm water and sugar made the yeast the most active, and the cold water alone was the least active.
We have left them in the classroom overnight to see if the yeast rises more through the night.

On Wednesday we started off our Kitchen science unit by doing a coke and Mentos experiment. We used coke, diet coke and even water to see the difference in chemical reactions. We learnt that the carbon dioxide in diet coke especially reacts with the surface area of the Mentos lollies, forming lots of little bubbles!
