Hands on science.

On Tuesday the 24th of November 2015, 3M went to the Hands on Science Workshop. We did four experiments . The first experiment was, using a themomerter. Next we used baking powder and citric acid to make bubbly sounds and a gas. We than got two cups to put hot water in one and cold water in the other.

Than we put food dye in both of them so we could see which one would will go to the bottom first IMG_1016IMG_1015

and the first one was the hot water. The last thing we did was we got a candle and had wire to put a little windmill and the fire on the candle made it spin that was it.
