Autumn 2 Irreversible Changes
This half term we are learning about Properties of Materials and Irreversible Changes
Today we looked at the scientist Alice Ball. She discovered a way to make oil soluble in water in order to advance treatment for leprosy
Discussing what variables are and how they can be used to create a fair test
More irreversible changes - did you know you can make 'plastic' from milk?! With supervision, heat 280ml of milk then stir in 1 tbsp of vinegar. It will immediately curdle. Strain off the solids and leave to dry. Come back to see our results!!
Starting to learn about irreversible changes - mixing a liquid and a solid which produced a gas. If you'd like to carry out this experiment with the aid of an adult you will need 60ml of vinegar and 2tsp bicarbonate of soda, with a glove attached tightly over a cup
Testing which cup would be the best for Mrs McLeod's coffee - learning about thermal insulators
Investigating properties of material outside
Investigating different materials and their properties
