On Thursday the 17th of July a lady called Sally came in from PrimeSci to teach 5S and 5P more about science. My group was chemical and physical changes, we learnt how to tell the difference between physical changes and chemical changes.

The most interesting thing I learnt was how chemical changes are different to physical changes. A physical change is, for example, you have a 5cm Lego block but it can’t move by itself so you put more blocks onto it, so now it’s a 15cm block.

I was surprised to learn that when you add a liquid to a chemical it can turn into a gas which I thought was cool. Learning about gases, liquids and solids made me think about why we have these things because you use liquids for dishes and cleaning windows, solids are plates and cups, but I liked learning more about gases.
At the end of our session Sally did an explosion with a dishwasher tablet and some water and it made a big BOOM! I really enjoyed Sally coming in to talk to us, it was really fun.
