Unit:
Author:
Debbie Abel
Intended Grade Level(s):
4th
5th
Subject Area(s) Covered:
Science
reflection/absorption
electromagnetic radiation
solar energy
Estimated Activity Length:
50 min
Learning Goal(s):

Students will learn that reflectors can be used to increase solar oven temperatures by concentrating solar energy. Students will use their observations from the prior lesson to make claims based on the concepts of reflection and absorption within a solar oven system. Students will use their observations from reflection and absorption experiments to determine how to best capture reflected solar energy.

Students will see a demonstration and conduct a simple experiment on reflecting sunlight.  During this demonstration, they will determine the purpose of the reflectors on a solar oven’s design and make observations about their functionality. They will use what they learn to build their solar ovens. View full description >>

Intended Grade Level(s):
4th
5th
Subject Area(s) Covered:
Science
absorption/reflection
electromagnetic radiation
solar energy
Estimated Activity Length:
50 min
Learning Goal(s):

Students will learn that darker colors absorb more sunlight and get warmer. Students will understand the relation of absorption to thermal radiation emission. Students will conduct an experiment that isolates color as a variable to test.

Students will conduct experiments using different colors of paper.  During this process, they will make observations about the functionality of different colors when incorporated into design in relation to reflection and absorption.  Students will use what they learn to build their solar ovens.

Intended Grade Level(s):
4th
5th
Subject Area(s) Covered:
Science
solar energy
electromagnetic radiation
energy transfer
Estimated Activity Length:
50 min
Learning Goal(s):

Students will learn how a professional solar oven works. Students will make scientific observations about the functionality of a solar oven. Students will practice prototyping through their own sketches of a solar oven.

Students will view a professional solar oven in use and hypothesize how it works.  They will do this through observing the oven in action as it cooks an egg, then recording their observations.  This will be recorded in their energy notebooks. View full description >>

Subject Area(s) Covered:
Science
Energy
solar energy
photovoltaic effect

electromagnetic radiation
greenhouse effect
absorption
reflection
conductivity
energy transfer
photons
electrons
Estimated Activity Length:
1 hour
Learning Goal(s):

Students will be able to describe, in basic terms, the way that electricity is generated from a solar cell. Students will be able to determine that energy from the sun is being converted directly into electricity. Students will understand that this electrical energy that is produced in this energy transfer is able to perform the work required within a small load.

Students will learn the basics of how a solar cell generates electricity and observe the effects on a small electrical load attached to a solar module under a variety of conditions. They will build upon
