Colorful Milk and the States of Matter

Colorful Milk 2

This week, Dora and I “studied” the states of matter. It is a subject that is covered in the ages 3-6 Montessori “curriculum”/album that I have. I think I’m going to wait on the rest of physical science until she is older though. It really seemed to go over her head. I tried demonstrating with melting ice in a jar, which I then heated until it formed steam, but she clearly didn’t grasp what I was teaching. The one thing she did grasp, is that water makes things stick together, such as hair and paintbrush bristles. I have no idea why this was the one thing she hooked onto during the week, but she has been spraying her hair with a water bottle all the time so that she can show everyone how the water makes it sticks together. For this unit, we did the famous colorful milk experiment that you see all over the internet these days, but which I personally had never heard of until I started reading blogs. You add several drops of food coloring to a dish of milk and then drop a bit of dish soap in the milk (you can also touch the milk with a q-tip that has been dipped in soap). The soap instantly sends the food coloring flying in all directions. (Here are some good “officially scientific” directions and explanations from Steve Spangler.) The picture above shows the milk after we dropped the soap in, below is the before shot.
