On Wednesday Ms davis and Ms Dudding ( Ms Kirkpatrick's friends ) came to do a experiment ( Elephant toothpaste ) with Panmure Bridge School. Our aim for the elephant toothpaste was to see a chemical reaction. I thought the elephant toothpaste would erupt and make bubbles. We learnt about Physical change and Chemical change. Physical change is when you make something but cant change it like e.g. cake you can't wait for it to dry and hope you will get all the ingredients you started now. Chemical change is when it is changed forever. I learnt that elephant toothpaste is not actually elephant toothpaste.
