About this worksheet
Five questions fill the single worksheet page of this 4th grade check, and page 2 holds the answer key. Students mark wind, coal, solar, oil, hydroelectric and natural gas with R or N, then pick the advantage and the disadvantage of solar energy from four choices each. Two short written answers ask what is burned in a coal power plant to make steam and why the supply of oil can run out. A photo of a coal plant sits beside question 4.
