Class Prac

Today we discovered that black cans trap heat more than white cans and I thought that it was quite interesting.

    It was interesting becasue near the start the white can was hotter than the black one. At the end the black can turned out to be hotter.

    Unfortunately, in this prac, we did not get to test out the siver can. Did you know that silver actually reflects more light than white?

    Black and dark colours -- absorb
    White and shiny -- reflect
    Clear and transparent -- transmmit.
