In the life cycle of a frog, what do the eggs hatch into next?
Tadpoles
Which gas do trees and plants take in (breathe in) to make food?
Carbon dioxide
Name two health or environmental problems caused by dirty smoke from burning trash.

What type of power plant uses moving wind to spin large turbine blades and generate electricity?
A wind power plant / Windmill (Wind energy)
If a mouse is trapped in a box with food and water, but no air holes, what will happen?
It will die because it does not have air to breathe.
What is one best way to protect a bird's life cycle when you see a nest in a tree?
Leave the nest alone and watch from a distance
Which gas do trees release (breathe out) that animals and humans need to breathe?
Oxygen
What is one action people can take to help reduce air pollution in a city or village?
Plant more trees, stop burning trash, ride bicycles, or walk instead of driving
How does wind help people in daily life?
It can make electricity, move sailboats, or dry clothes.
What is one action humans can take to help protect wild animal habitats?

Why are wind power plants usually built in large, open areas?
Open areas get lots of strong, continuous fresh wind to turn the generators.
Explain why plants cannot make food at night or in a pitch-black box.
Plants need sunlight (light energy) combined with carbon dioxide and water to produce food.
