This week has been science week across KS1 and KS2. We have many more updates to follow but here’s a taster of what Year 3 have been up to this week!
First of all we experimented with using vinegar and salt to clean old pennies. We discovered that the salt and vinegar solution removes copper oxide from the coins making them look bright and shiny again. We left some of the coins for a while and discovered that green malachite had started to form on them.
Next we made some lava using vegetable oil, water, and food colouring. We discovered that water is denser than oil and that by dropping salt in the mixture we could make ‘bubbles of oil’ move around so it looked like a lava lamp!
Finally we experimented with oil and water by dropping fizzy tablets in to our mixture. We found that no matter what we did the oil and water would not mix and they settled back into different layers.
We had a great week and really enjoyed it! What have you done in your class this week?
