SCIENCE IN THE SUN: Alexa Moscatello measures the temperature of soil

Understanding energy

Fourth-graders in Laura Offerding and Alyssa Perez’s class recently explored energy transference by conducting simple experiments. The students collided marbles rolled at different speeds to observe the effects and transference of kinetic energy from one to another.

They also measured the temperature of soil that had been placed in the sun, comparing the temperatures to soil left in the shade. This demonstrated how solar energy is transferred into radiant energy and, through photosynthesis, will be converted into chemical energy stored in plants. They made the connection that when humans ingest vegetables and fruits, we store the energy as chemical energy again and then use it for motion, growth and metabolic processes, and heat. So in a way, the sun is in all of us.

Understanding that energy cannot be created or destroyed, only transferred into other forms, is a fundamental concept in physical science, an important unit in the fourth grade science curriculum. The students will soon go on to explore open and closed circuits, and examine how the chemical energy stored in batteries is converted to electrical energy that powers lightbulbs in the circuits.

To conclude the unit, the students will look at renewable and nonrenewable energy sources.
