We got a new packet and it was about heat and energy. and also did a lab involving the three phases of water, which is gas, water, and liquid. We got a ice and put it in the beaker, then heat it until it became a liquid, then gas. We measured the temp every 15 secs and the temp changed often. The elephant toothpaste was such and exciting demo lab to see because we saw mr. olson mix a whole bunch of liquids together and saw the toothpaste form and heat coming out from it.
