LAVA LAMPS we were making lava lamps

in the lava lamps oil stays above the water because the oil is lighter than the water or, more specifically, less dense than water. The oil and water do not mix because of something called “intermolecular polarity.” Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together (drops.) This is similar to magnets that are attracted to each other. Oil molecules are attracted to other oil molecules, they get along fine as well. But the structures of the two molecules do not allow them to bond together.

In the lava lamps the ingredients are:               we were learning about the science behind lava lamps 

- oil                                                                   i found it hard to... learn the difference  stuff in the pill

-water                                                                i found it easy... to put in the pill to cause it to fizz

-food colour                                                        next time i will... add more water
