Lesson 34 of 84 ยท Human Impacts on Earth

Experiment

Renewable Energy Technology (Part 2)

What You'll Learn

Renewable resources like solar panels and wind turbines generate clean energy. Human innovation in engineering continues to make these technologies more efficient and affordable.

Key Words

  • prototype
  • design

Materials Needed

  • paper clips
  • rubber bands
  • string
  • cups
  • aluminum foil
  • ruler

Safety First

  • Do not look directly at the sun or bright lights.
  • Clean up spills immediately to prevent slipping.
  • Use materials only as directed in the experiment.

Steps

Step 1 โ€” Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 โ€” Do

Build a simple seismograph using a pen, cup, string, and paper. Shake the table and record the marks. Can you detect bigger vs. smaller shakes?

Step 3 โ€” Observe

Draw a detailed diagram of what you observe.

Step 4 โ€” Record

Write a conclusion: what did your results show? Did they match your prediction?
