Science Week with Year 3

Over the week, we have been having some great scientific fun and carried out a number of different experiments using things we could find at home.

Our first experiment involved getting raisins to dance. We used some lemonade and watched as the raisins moved around. We then talked about why we thought this happened.

Our second experiment involved making a lava lamp using water, food colouring, oil and salt. We watched as the oil that was on the top of the water was pushed to bottom and then moved back to the top. We found it fascinating! We discussed how this happened.

In our third experiment, we tried to make it rain a a rainbow, using shaving foam, food colouring and water. We watched as the drops of food colouring filled the ‘cloud’ and then fell like a rainbow of rain below.

Our last experiment saw us add food colouring to a plate of milk and watch some parts of it change colour. We talked about why it did not change colour like the water did. Then we added a drop of washing up liquid and whooosh!! the milk changed!
