General
In this lesson, students conduct an experiment and make observations to learn how the sun warms the Earth’s surface, specifically water. The lesson also includes a printable worksheet where students can take notes and sketch what they observe!
Standards
NGSS:
K-PS3-1
Learning Objective
Students will be able to make observations to determine the effect of sunlight on the Earth’s surface.
Introduction
Ask students what they know about the sun. Explain that the sun is a star that gives off heat and light. Then explain that we live on the Earth’s surface or the outer layer of Earth. Finally, teach students about making observations. When we make observations, we use our five senses to notice details. Before beginning the experiment, explain that students will use their five senses to make observations. Review the five senses and explain that it is not always safe to use each sense when making observations during a science experiment so it’s important to be safe! Next, explain that scientists take notes to record observations and they may also sketch and label pictures.
Instruction
Students may work independently or in groups/pairs for this experiment. First, label the cups for each student or group. Each student or group will have two cups, one labeled “sun” and one labeled “shade.” Both cups should be filled with room temperature water. At this point, students should make observations and record what they notice on their worksheet. Then place the cup labeled “sun” in the sunlight and place the “shade” cup in a shady area. After a couple of hours, retrieve the cups and have students record new observations. What changes do they notice? Have students share their results with the class. After this, observe the picture on the board. Tell students to drag the magnifying glass to identify the warm cups of water. Slide the picture to reveal the answer.
Quiz
Students respond to ten multiple-choice and true/false questions.
Closing
Ask students why the sun is important to us and what effect it has on water. Then check understanding by having students drag the circle to respond to the multiple-choice question.
Instruction materials
The following items are needs to conduct the experiment:
- plastic cups
- permanent marker
- water
- windowsill (area exposed to sunlight)
- shaded area
The lesson includes a printable worksheet for students to record their observations.
