Molecules and Marshmallows!
Using toothpicks and two sizes of marshmallows, the students made as many creations as they could. After a while of creating they drew pictures of their favorite ones. We then placed a rule on our creations. Each large marshmallow can only have three toothpicks coming off of it. The students could still create many different structures. We then moved to two toothpicks per large marshmallow, finally moving to only one toothpick. Afterwards we discussed how each time we put a constriction on how the structures could be assembled, our possibilities for creating were constricted as well. This drove the point home that each atom having a certain amount of bonds allows certain molecules to be formed. There is order instead of chaos.
opposed to room temperature water, which we observed last week. The students helped put
together our experiment making sure the variables were all equal to make the experiment true.
Ahead of time I had put ice in one bowl of water and heated another bowl of water. We put one cup of cold water in one cup and one cup of warm water in another. We put yellow food coloring
in two droppers and blue food coloring in two others. On the count of three one drop of yellow
and one drop of blue were dropped into each cup. The students observed that the colors mixed much more quickly in the hot water than the cold. We concluded that the molecules in the hot
water must move more quickly as well. We drew pictures of each cup showing the mixing of the
colors, along with a drawing depicting the movement of the molecules in each temperature of
