KIA Elementary School Kobe’s G3 students are learning about “how the world works” as a flow of inquiry, covering “various types of energy,” “how energy changes,” and “how energy is produced. The central idea is “Energy can be converted from one form to another” Through experiments, we explore what kind of energy is at work and how energy changes.

First, we chose an experiment from the book “Energy Lab For Kids” to see what kind of experiment would be best to introduce to the children about the changes in energy. The teachers conducted preliminary experiments on their own to ensure safety and to figure out how to conduct the experiments efficiently with the children.

The first experiment was the movement of water. This was done during the introduction of the unit. We moved the water from a full bucket to an empty bucket. The bucket full with the water could only be moved up and down. I also told them that they could only use the long hose and the long tube. The children were very creative in using these tools. They connected them well to prevent spills. However, the water just wouldn’t move. After some trial and error, they began to realize that water goes from high to low. or “It’s too high and the water won’t go anywhere! It took about 15 minutes to successfully move the water. After returning to the classroom, we thought about why the water moved.

Now, here’s the main point. We placed a can of water on the flame to see how the temperature would change. We measured the temperature of the water in the can, and after it was exposed to the fire, we measured it again. I asked them to predict how it would turn out. I expected them to focus on the temperature, but they predicted that the can would cave in, or that the can would turn black. After the can was set on fire the temperature was measured.

As you can see in the picture above, it burned well. When they saw this, they said, “Oh~! “A meteorite! “It smells good!”

The temperature rose from 26 to 35 degrees Celsius. It turned out that fire could raise the temperature, afterall. I asked the students to think about how much the temperature would rise if we burned the three snacks. “One child said, “I think 62 degrees!” said one of the children. When I asked her why, she replied, “When I had one snack, the temperature was +9 degrees, so I thought three snacks would be three times that, or about +27 degrees…” She was very logical. I actually burned three of them and checked the change in temperature.

The result was 59.5 degrees Celsius and +35 degrees Celsius. The teacher said, “That’s close to the temperature we all expected. But it didn’t exactly triple…” One of the children said, “Maybe the snacks are all shaped differently, so the temperature didn’t exactly triple.” Then the class was convinced.

The students love the experiment at KIA Science Lab and wanted to do it again! In the future, we will use this experiment again to explore how energy changes.
