we got a new packet this week.
it was about heat and energy.
we also did a lab involving the 3 different phases of water: gas, liquid, and solid.
first, we got a piece of ice and putted it in the beaker.
then , we started heating it up until it became liquid, then gas.
we had to measure the temperature every minute for 15 seconds.
the temperature increase then decreased a little then increase.
it was not very stable.
we made elephant toothpaste!
i forgot what it was made from. but the result was some very hot yellow foam.
it cooled down fast though.
that was about it for this week.
