Welcome to Year 5!
We have had a busy and exciting first half term back in Year 5. To finish off our half term, we have spent 3 days exploring the properties of materials and how to separate them.
First we learnt about Reversible and Irreversible changes. We tested bicarbonate of soda with vinegar and quickly learnt that this was irreversible due to a new gas being produced. Thankfully, the sun was shining and we were able to venture outside and test out what happens when mentos sweets are added to diet coke.
This irreversible change highlighted the importance of having a stable base to carry out the investigation on.
For the remaining two days we investigated different ways to separate materials such as a salt solution and a muddy mixture.
