Our first experiment demonstrated that matter takes up space. In this experiment we filled a cup with water. We marked the level of the water on the outside of the cup. Then, we added five rocks, one at a time. After adding each rock, we stopped to observe the change in the level of the water. The children reached the conclusion that the rocks pushed the water level higher, because the rocks and the water could not be in the same place at the same time.
You may want to replicate our second experiment at home. Here are the steps we followed:
First, fill a large bowl with water.
Then, place a paper towel in the bottom of a cup.
Next, turn the cup upside-down and put it in the bowl.
After that, count to ten and take the cup out of the bowl.
Finally, look inside the cup.
The children are natural scientists. They worked together to complete the steps of both experiments, and they bravely entered into our discussion about the results. Throughout this unit we will be asking questions like: What do you think will happen? What happened? Why do you think this happened?
Stay tuned for more updates!
