EARTH DAY SCIENCE LESSONS AND PROJECTS for ALTERNATIVE ENERGY
Alternative energy science projects explore wind power, water power, solar power, and biomass power with Earth Day hands-on demonstrations for teachers of Prek-K-6 students in classes or homeschools.

Almost all our non-nuclear energy comes from the sun, either directly from solar panels, or indirectly, from the power of falling water, the force of wind, or the heat from chemical reactions involving the growing things we call biomass. Gas, coal, and oil are products of biomass created by the sun that have have been buried, partially decomposed, for millions of years.

Solar Power and Biomass
Science Lesson Plan Demonstration

When air near the earth is heated by
the sun, it rises high into the sky and
cold air from elsewhere pours in to replace it. This pouring air is wind, and
it is powerful enough to drive a sailing ship across the sea or turn the mighty
blades of a generator in a windfarm.
Every day, the sun draws billions of gallons of water up from the sea into
the air where it condenses into clouds.
In time these clouds shower the water back to earth, where it flows down
again to the sea. Mill wheels placed alongside that flow can produce
wonderful, clean energy,
as can generators below high dams.
Here is an easy demonstration of how sun creates biomass. The sun enables plants like corn and soybeans to grow and produce oils that in turn can be
used to fuel machines producing alternative energy. Unlike gas and oil
and coal, these sources of energy are renewable with every growing season.

Science Lesson Plan Demonstration

One problem with traditional energy sources like coal, oil, and gas
is that they produce gasses and tiny particles that can foul the air
and produce smog
when tiny droplets of water condense around them.
