Grade 4 students master the law of conservation of energy and identify the sun as the original source of most energy on Earth. This worksheet traces food, gasoline, and wind energy back to sunlight through clear chains. Multiple-choice questions and fill-in-the-blank items help learners explain why energy cannot be destroyed, only transformed. Strong NGSS 4-PS3 alignment makes this worksheet a capstone challenge for the energy unit.
Style:
Energy: Forms and Transfer
Part A: Multiple Choice
Circle the best answer for each question.
1. Why do scientists say energy is conserved in every system?
A) It disappears when used
B) It only changes form, never created or destroyed
C) It doubles each time it transfers
D) It can be made from nothing
2. What is the original source of the energy in the food you eat for lunch?
A) Wind
B) The sun
C) Ocean tides
D) Rocks underground
3. A car burns gasoline to move. Where did the energy in gasoline first come from millions of years ago?
A) Lightning storms
B) Sunlight captured by ancient plants
C) Volcanoes
D) Earth's core
4. Wind turbines spin to make electricity. What is the original source of wind energy?
A) Earth's gravity
B) The sun heats air unevenly
C) Ocean salt
D) Underground water
Part B: Fill in the Blank
Write the correct answer on each line.
1. The law that says energy is never created or destroyed is called the law of conservation of energy.
2. Almost every energy chain on Earth begins with the sun.
3. When energy transforms, the total amount in the system stays the same.
4. Plants capture sunlight and store it as chemical energy in their leaves and seeds.
5. Even though some energy turns into heat or sound, it is not lost; it is just transferred to the surroundings.
