Renewable Energy: Sail Cars!

Answer: Energy is the ability to do work. Energy comes in many forms: chemical energy, electrical energy, heat energy, light energy, mechanical energy and nuclear energy. Question: What Is Energy?

“Energy is neither created nor destroyed.” The amount of energy in a system is conserved over time. Conservation of Energy

Examples of renewable energy: solar, biofuel, wind, geothermal, hydropower LIMITLESS Examples of nonrenewable energy: fossil fuels (coal, oil, natural gas) LIMITED Renewable vs. Nonrenewable

A type of renewable energy provided by the wind. Wind turbines  Brainpop: Wind Energy

Concentrated Solar PV Cells Solar Energy

Wind Turbines

Hydropower

Other Types of Renewable Energy Biofuels Supply Chain hydro/tidal biofuels geothermal

In groups of two, design a sail to propel your car forward using the wind from a box fan! Each group receives a base with axles and wheels. Use the given materials to design a mast and sail that propels your “sail car” forward. Be creative and don’t give up! Sail Car Challenge

Sail Types

 What are our constants?  car base – cardboard rectangle of the same size and shape  axles – coffee stirrers  wheels – Lifesavers® mint candies  What are our variables?  sail material  sail design  mast material  mast design  Can you think of any other constants?  Can you think of any other variables? Scientific Method
