Wow! What a wonderful week we have had in Year 4. It has been absolutely full to the brim with experiments, investigations and observations. We have focused our week around the book ‘Charlie and the Chocolate Factory’ as it fit in so well with our Science topic of ‘States of Matter’.
As well as taking part in a forensics workshop and Mad Science workshop, we have also conducted many investigations. From melting ice lollies and chocolate to observing chemical reactions, we have well and truly expanded our knowledge of solids, liquids and gases.
Take a look at some of the activities we did!
We investigated which lollies melted the quickest so that we could advise Mr Wonka on how to best design his ice lollies.
We investigated which materials slowed down the melting process best. We were surprised to find that the materials that keep us warm actually worked the best at keeping the ice lolly frozen.
We learnt that different materials have different melting points so we investigated whether different chocolates melted at different rates.
We observed chemical reactions and discussed how we knew that a gas had been created.
We made slime! We discussed words like atoms, molecules and polymers.
We investigated the best method for making a milkshake frothy.
We played with ‘gloop’ and noticed that it had the properties of a solid and a liquid. We discussed how this made it a non-Newtonian material.
We made rockets using film canisters, water and vitamin C tablets. We observed how an irreversible chemical reaction took place and a gas was formed.
We made sherbet – YUM! We noticed how our saliva reacted with the bicarbonate of soda to make a gas that made it fizz on our tongue.
We finished the week by watching the film of ‘Charlie and the Chocolate Factory’ and eating an ice lolly!
