Applied Science- Students Go Solar
Grade Levels- 5th-7th (California 6th grade Science Standards)
Unit Duration- 12-15 periods of 45 minutes.... can be extended considerably as desired.
Tools & Technology- Basic:Thermometers, cardstock, scrap cardboard, foil, tape, plastic wrap, overhead acetates.Internet Connectivity * Great if you can- diffraction grating, cardboard tubing, mirrors, penlights/lasers,....... handheld sensors for temp& light, cameras.
This unit on Solar Energy has been designed and used with students to meet the diverse needs of teaching fundamental science concepts about energy in earth systems, expository or "science" writing, meaningful uses of a range of technologies, and a high level of student interest and engagement. In addition, the extensions for science, math, language, and social studies are great.

Science, the big ideas- Energy from the sun powers our weather, which in turn affects climate, which is a key environmental factor for all living systems, both land and sea. Importantly for the full implementation of this unit, students can construct knowledge about light from the sun, and how it converts into heat- applied science in solar technologies- and into the food web through plant photosynthesis. The activities shown here, and the numerous extensions and resources supplied, are a great way to start the school year with an excited, skillful, and knowledgable group of scientists in your class.
Writing Skills- Two complaints often heard from high school science teachers are:
"Why didn't they teach any science?"
"Why can't these kids write an experimental conclusion that uses the data?"
Clearly the pressure to do the 3 R's has marginalized the time spent on science in many classrooms. However, it is sensible, and quite possible, to build expository writing skills in hands-on science units- teach the skill you expect students to demonstrate. The basic lesson set in this unit is meant to be assessed by a 3 paragraph essay that uses data and concepts from 3 activities to address the statement-" Some people say that energy on the earth all begins with the sun".
Technology- All of the core activities can be done with the minimum of teacher internet access, basic classroom supplies, and thermometers. However, many layers of richness in student inquiry and skills can be added with other technologies such as cameras, handheld sensors, and free or inexpensive science supplies ordered ahead of time. If targeted internet research for information and presentation is a goal, the resources are excellent for primary through advanced reading levels.
Math and Social Studies- A few suggestions for extensions are made, but your own creativity and needs will be your best guide.
