Sinking in Ice


"This experiment will show you how dead plants and animals can end up frozen solid."
Fill a container half-way with water. Put in freezer until the water is frozen. Place a rock on the ice. Leave in freezer. On about two hours, check on the ice. You will see that the rock has begun to sink into the ice. The rock is embedded into the ice. When you apply pressure to ice, it begins to melt. This is differnt that all other substances, which when you apply pressure they tend to turn solid. Once the rock melted the ice by it's weight, the water was pushed up around the rock and then refroze. This process happened over and over again, the rock digging its way into the ice.

  1. Another excellent idea for a simple experiment. What do the numbers after the title mean? (e.g., 7.2)

  2. I am so glad you asked that question! I am afraid that I can't take credit for these ideas. I am just a collector of good ideas, not an inventor of them! A number of people are intimidated about the transition between Apologia's elementary science books and their middle-high school science texts, so I decided to post us doing the experiments to show them that they had nothing to be scared of. I post them on the label of the title of the book and the numbers on the headings are the chapter/experiment numbers. I hope that clarified things. Please write again if I have been too confusing!
