Lava lamp science
We have been learning how to conduct a science experiment this week. We need to watch closely and record EVERYTHING we see. It is hard work. We watched what happens when you pour oil into water. We saw what happened when you put slat in. Then this week we changed one thing to see what happened. We were in groups and each group got to see one thing changed. For three groups the liquid was not water. It was lemonade or vinegar or hot water. The other three groups had oil and water last week but used washing powder, sugar or baking soda instead of salt. There was so much to see and we were surprised by some of the action happening in the jar. As us how to set it up and have a look at home!
