Global warming, ozone depletion, skin cancer risk . . . all of these themes appear frequently in the news. Yet, there are many misconceptions about them. This unit allows students to explore the science behind energy use and changes in the atmosphere. At the same time, students learn basic physical and earth/space science concepts related to light and electromagnetic radiation, the atmosphere, fossil fuels and combustion. Students also learn about the carbon cycle, the role of carbon dioxide in living systems and the important role of skin in protecting living organisms. Finally, students have opportunities to integrate their knowledge through explorations about the greenhouse effect, climate and alternative energy sources. Overviews of the science content covered in each section of this guide can be found in the one-page Physical Science, Life Science, and Environment and Health Basics overviews. The introduction to each activity also provides a summary of science concepts covered.
This pre-assessment is designed to allow you, the teacher, to estimate students’ existing knowledge about these topics before beginning the unit. It also can be used for self-assessment by students once the unit is completed.
Objectives and Standards
Allows teacher to estimate students’ prior knowledge related to the atmosphere, carbon cycle, skin and skin cancer risk, and climate change.
Materials and Setup
Materials per Student
Copy of “Do You Know” student sheet
Have students work individually to complete the pre-assessment.
Procedure and Extensions
Initiate a class discussion about sources of energy and energy use. Ask questions such as, What is the source of energy for your family’s car? What about for your computer? Where does the energy we need come from? To build awareness, have students make a class list of the many different ways in which they rely on energy each day.
Follow by asking, Do you think our uses of energy affect the environment? Tell students that they will find answers to these and other questions over the next few weeks.
Give each student a copy of the pre-assessment. Have students complete the pre-assessments individually. Tell students that they will not be graded. Rather, they will use the pre-assessments to gauge how much they have learned over the course of the unit.
Collect completed pre-assessments and save them. Students will refer back to their answers at the conclusion of the unit.
Handouts and Media
Students learn about Earth's atmosphere and the greenhouse effect, identify where children live based on their clothing, make a sundial, and model Earth's atmosphere.
Students investigate different sources of energy and how they can affect the atmosphere and global ecology. (11 activities)
Riff and Rosie, Mr. Slaptail and their neighbor, Beulah Diggerpaw, have an adventure while learning about energy use.
