British Science Week

 As part of British Science Week we have conducted a gummy bear experiment. We started by putting a gummy bear into a glass of water and saw that after 24 hours it had grown considerably. We then thought it would be interesting to see what would happen to a bear if left in water containing other elements, such as lemon juice, salt and vinegar. We talked about what we would need to do to ensure it was a fair test and then set up our experiment. The bears were left in petri dishes on the tables so we could all see what was happening over the 24 hours that they had ben left. We then created a table to record our information and then a bar chart so we could see our results clearly.

On Friday, we demonstrated how the human digestive system works with the use of some bread, water, lemon juice and washing up liquid as well as a sandwich bag and a pair of tights! In our groups, we had a go at ripping the bread into pieces with our hands to demonstrate the job of the teeth and placed the bits of bread into a sandwich bag. Then, we began mashing it with our hands and adding some water, lemon juice and washing up liquid to perform some more mashing. (The water was acting as the saliva and the lemon juice and washing up liquid were acting as the acid and enzymes that help to break our food down.  Afterwards, we handed it over to Mrs Hurst as it got quite messy from here on out! We gathered around the demonstration table and watched as each group came and squeezed the masticated bread into the pair of tights. Poor Mrs Hurst ended up with quite a lot of it on her hands!   Then it was completely over to Mrs Hurst to demonstrate the job of the small and large intestine. Here
