Which plant's soil absorbs the most heat?
 By: Meghana

To answer this question, I planted a sunflower, a bean plant, and a radish plant. I planted each plant in a different cup and took the temperature of each plant's soil every day. All of the plants stayed underneath a grow light and I watered them almost everyday with water that was the same temperature. After that, I took all of the temperatures and averaged them to the nearest whole number. The sunflower absorbed the most heat. The bean plant and the radish plant were both tied for second place.

 Which landscaping materials absorb the most heat?

For this question, I put sand, dirt, leaves, rocks, and water in a different cup. All of the cups stayed underneath the same grow light. I took the temperature almost every day and recorded it. At the end, I took the temperatures for each material and rounded it to the nearest whole number.

The results are as follows:  About Global Climate Change: Global climate change is often referred to as global warming. People started to think about the Earth's climate in the 1800s. It was brought to our attention during World War II. The soldiers' weapons were being greatly affected by the temperature, so the United States started to do some research. People started to actually be concerned about global climate change in the 1980s.

Global warming is said to have happened for many reasons. Scientists divide them in to two groups, man-made and anthropogenic causes. Man-made reasons do the most harm. Anthropogenic causes are the natural causes that are causing global warming. One example of an anthropogenic cause is methane gas. Methane is a greenhouse gas. Greenhouse gases are gases that are traps heat into the Earth's atmosphere. Methane comes from the arctic tundra and wetlands. Pollution is the biggest man-made cause. Burning fossil fuels is the largest source of pollution. Examples of fossil fuels are coal and gasoline. Cars burn fossil fuel, so it is recommended that you carpool and use public transportation. Of course, that is not possible for everyone to do. Trees give out oxygen, so it is not good to cut down too many trees. If you do cut down trees, you should always plant a new one. People are usually cutting down trees ,and they use the property to build a new building.

Overall, global warming is affecting the Earth and we need to start to take action. You can solve global warming by: Of course, it is very difficult for our lifestyles to meet what I have typed above.

To answer my question, I modeled global warming and the greenhouse effect taking place. I placed two cups of potting soil under direct light and monitored their temperature and tested them. I placed a glass jar over one of the cups and the temperature increased. Then, I sprayed water on the inside of the jar and it cooled the temperature down. The water vapor represented the atmosphere which traps heat. The potting soil represented the Earth, and the light as the Sun.
