Solar Cooking (Lesson Plan)

Solar Cooking (Lesson Plan)

(Warming Up to the Properties of Solar Radiation & Its Uses in Our Homes)
Suggested Grade Level  6-8

Overview 
Students experiment with a virtual solar cooker to discover the mathematical relationships among reflection, transmission and absorption. They won’t stop there, though! Students then apply their knowledge to building and testing a solar cooker of their own invention. In an extension, students investigate how these principles can be used as sustainable energy sources for homes in Pennsylvania through passive solar heating. Approximately two to three (2-3) 50-minute class periods are required for this lesson.

Solar Cooking

Background: The sun gives us energy. It provides the earth with heat and light. It helps grow food, makes
weather, and keeps living things alive. We can use the sun’s energy in many ways. When we burn wood in our fireplaces, we are
releasing the sun’s energy. The wood stores the energy from the sun and releases it as heat. We can use the sun’s energy to
cook food.

School Science Project for Energy

Solar energy can be used to heat our homes, heat water, cook our food, and power our lights.

These science projects will help you learn about solar energy and how it works. The first three projects focus on different ways to use solar thermal  (or heat) energy. The fourth project focuses on solar electric energy.
Each project is broken into several parts:

• Z The purpose of the experiment
• Z The materials and equipment you will need to do the experiment
• ZWhere to find some of the materials
• Z How to assemble and conduct the experiment
• ZWhat you may see during the experiment
• Z How the specific energy type works.
• Some of the experiments may require help from an adult.

Solar cookers require direct sunlight to function properly. Shadows, clouds and inclement weather limit their effectiveness. In general, you can solar cook when the length of your shadow on the ground is shorter than your height. This is an indicator that the sun is high enough in the sky to cook.

You can typically solar cook two meals per day — a noontime meal and an evening meal. The sun is most intense between 10am and 2pm, which is when breads and pastries should be baked.


Global Sun Cooker

Light-Weight, Easy-To-Carry: The Global Sun Oven weighs 9.5 kg, folds up like a suitcase, and is equipped with a handle for easy transport.

One-Piece Collapsible Reflectors: Set up for use or taken down for storage in a matter of seconds. The reflectors literally fall into place at an angle that allows you to maximize the power of the sun. The reflectors are made of highly polished, mirror-like anodized aluminum that can be cleaned quickly and easily with glass cleaner, and they will never oxidize or rust.

Spill-proof Levelator: There is never any need to worry about your food spilling in a Global Sun Oven. While cooking, your food rests on a shelf that self-adjusts to always stay level as you refocus.

Self-Contained Leveling Leg: As the sun is at different points on the horizon the Global Sun Oven can readily be adjusted to follow it. A simple adjusting leg allows you to choose from 9 angled positions. All that is required is to watch the shadows created by the oven. When the shadows are even on all sides, the cooker is directly focused. A good rule of thumb is to plan to readjust every 30mins to maintain maximum heat.

At noon, the sun is high in the sky and moves quickly past the maximum focus point, creating the need to refocus more often. Later in the day, you will not need to refocus as often. Many meals can be cooked without refocusing. Global Sun Oven users often will put their ovens outside, focused for the mid-day sun, with their dinner in it when they leave for work in the morning.

Dark, thin-walled pots with lids work best. Dark pots change the light from the sun into heat energy. Lids are important because they hold steam in the pot. Shiny aluminum pots and pans cause light to be reflected out, thereby reducing the oven's temperature. Add 10-15mins of cooking time for each time the oven door is opened.
