๐ŸงชLab Brief #78

Engineering and Design.

๐ŸŽฏ Your mission

Run the sim. Spot the pattern.

โšก The twist

Every solution creates a new problem. That's good โ€” that's the next project.

๐Ÿคฏ

Mind = Blown

๐ŸŒ‰ The Eiffel Tower can grow 6 inches taller in summer because metal expands when hot.

๐Ÿ”ฎ

Make a hypothesis first

Predict: which design will hold the most weight?

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

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?
