This week, since I had a good excuse, we did a fun chocolate investigation to study the changing states of matter. Here's how it went...
First, I had the kiddos observe their baggie of chocolate chips. They used a graphic organizer to draw the chips and circled to describe their state of matter. Then, the students "applied heat" by squeezing gently or lightly breathing on their bag for two minutes--for some reason the boys really loved breathing on their bags!
Next, they drew what their chocolate looked like and circled to show the state of matter.
Then, we put the chocolate baggies in the freezer for five minutes. (During this time, we watched a quick BrainpopJr. video on the Changing States of Matter). After the five minutes were up, we opened the bags to see that the chocolate had in fact returned to a solid shape--this time, the shape of the bag.
Afterwards, we discussed what they learned about temperature and its effect on the states of matter. Yay for this sweetie, sounding out temperature!

Have a great weekend!
