Liquid Chalk

 After we played with our solid chalk this week we were wondering if we could make a liquid chalk.  By combining water, corn starch, and food coloring we made Liquid Chalk.  We discovered it was very difficult to write with our liquid chalk.  We used sponges, sticks, leaves, and anything else we could find to write with our liquid chalk.  Some friends discoved that by adding more water the liquid chalk was easier to draw with.  Check out our discoveries here, Liquid Chalk.

Frozen Watercolors

We started our exploration or water this week with watercolor paints.  Yesterday we made our own liquid watercolors and painted with them. Then we predicted what might happen if we put our liquid watercolors in the freezer. When we got to school today we found out they had frozen and turned into a solid! We had a lot of fun painting with our colored ice cubes.

Liquid vs. Solid

This week we learned all about liquids and solids. We discovered that solids hold their shapes like a block or a pencil. We learned that liquids fill the shape of their container like glue, or water. In our experiment we found that water, apple juice, lotion, and kinetic sand were all liquids. We discovered that blocks and pencils are both solids. Our discussion about kinetic sand was awesome! It had to be a liquid because we could not hold it in our hand and it changed shape on its own. We then discovered that if we just had 1 little piece of the sand it would keep its shape so, each individual piece of sand is a solid.
