Renewable Energy Technology (Part 2)

๐ŸงชLab Brief #34

Engineering and Design.

๐ŸŽฏ Your mission

Predict it first. Then prove yourself right (or wrong).

โšก The twist

The first design always fails. That's the point.

๐Ÿคฏ

Mind = Blown

๐Ÿ› ๏ธ The first computer bug was a literal moth stuck inside a machine in 1947.

๐Ÿ”ฎ

Make a hypothesis first

Guess: what's the weakest part of this build?

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
  • constraint

Materials Needed

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

Safety First

  • Do not mix unknown chemicals together.
  • Tie back long hair before starting 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?
