we had to make lava lamps using: water,oil,dye and aspirin.
first we put in water then oil but the water and oil don't mix because oil is heavier then oil,then we put in the dye then we put broke the aspirin into little pieces in the glass and it sank to the bottom and started dissolving and created gas.
i think it did that because of the carbon dioxide the gas made the dye start floating
I was learning about making lava lamps
we also learnt some stuff about molecules
I found it easy to adding the water and oil
I enjoyed adding the aspirin
I found it hard to putting the dye in.
Next time i will
