Lesson Total number of panels needed for a home.
Experiment with data, and who knows? Perhaps one of your students will come up with a groundbreaking efficiency formula!

Lesson Plan: Design and Build

Objective: Foster innovation by designing a model that utilizes solar energy.

Unleash the creativity! Let students design their solar power-based applications, from simple solar-powered phone chargers to more complex models like automated solar-driven irrigation systems for gardens. This project can be a competition for the most innovative design.

Lesson Plan: Solar Oven S'mores

Ages: 7-10 years
Objective: Teach students about solar energy

Materials Needed:Pizza box, black construction paper, aluminum foil, plastic wrap, tape, a stick to prop the lid, and marshmallows, chocolate, and graham crackers for the s'mores.
Process: Have students line the bottom of the pizza box with black paper, cover the flap with foil, and seal the window with plastic wrap. Place the s'mores inside and angle the box towards the sun. The solar oven demonstrates how solar energy can be converted into thermal energy—delicious thermal energy!

Lesson Plan: Water Purification Station

Ages: 8-12 years
Objective: Demonstrate solar water disinfection.
Materials Needed: Clear plastic bottles, dirty water (safe to handle), sunlight, and time.
Process: Fill bottles with water and place them in direct sunlight for several hours. Solar UV radiation helps kill pathogens, showcasing an important use of solar energy in improving health and environment.

Lesson Plan: Sun Tracking

Ages: 10-14 years
Objective: Observe and record the sun's path.
Materials Needed: A sundial or a homemade version with a stick and markers.
Process: Students set up the sundial and mark the shadow's position hourly. This helps students understand how solar panels can be optimized by angling them towards the sun’s path.

Lesson Plan: Balloon Pop Challenge

Ages: 11-16 years
Objective: Explore solar thermal energy.
Materials Needed: Black and white balloons, string, sunny day.
Process: Inflate one black and one white balloon. Hang them in direct sunlight. The black balloon absorbs more light and heat, popping first. This experiment helps understand light absorption and its consequences.

Lesson Plan: Solar-Powered Cars

Ages: 12-16 years
Objective: Harness solar energy to power a vehicle.
Materials Needed: Solar car kits or materials to build DIY solar cars.
Process: Students build cars powered by small solar panels. Races can be organized to test whose car is the fastest, teaching about the practical application of converting solar energy into kinetic energy.

Lesson Plan: Photovoltaic Power

Ages: 10-16 years
Objective: Illustrate how solar panels produce electricity.
Materials Needed:** Small solar panels, multimeters, various resistors.
Process: Connect the solar panel to the multimeter. Experiment with different resistors to see how they affect the electrical output.

Lesson Plan: Solar Art

Ages: 7-12 years (teacher demonstration/close supervision)
Objective: Create art using sun-sensitive paper.
Materials Needed: Sun-print paper, transparent objects/leaves, sunlight.
Process: Arrange objects on the sun print paper and expose it to sunlight. The area under the objects stays light, while the exposed areas darken, creating beautiful prints.
