A Peek Inside the Lesson
This is the real lesson text your child hears, read aloud by a friendly voice.
Natural resources are things from nature that people use: water, soil, trees, sunlight.
Renewable resources can be replaced, like trees we replant, or never run out, like wind.
Nonrenewable resources take millions of years to form, like oil, coal and natural gas.
When we use nonrenewable resources, they are gone. So we must use them wisely.
Many countries now build solar panels and wind turbines.
