Science with Trish

    Yesterday me and my class went to science in Room 19 we learnt about density by making rainbows with blue made with a sugar base,green with less sugar,oil and red with no sugar at all.This was the order we did it in ... blue, green, yellow, red then we did it the other way round when we did it this way it made the exact same rainbow by density so think it like this we have a balloon it is very light because it is filled with gas we also have a marble since it's solid the balloon is lighter that means the marble is denser.
