Human Impacts on Earth.

๐ŸŽฏ Your mission

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

โšก The twist

What the body does in one minute is wilder than any cartoon.

๐Ÿคฏ

Mind = Blown

๐Ÿ™ An octopus has 9 brains and 3 hearts.

๐Ÿ”ฎ

Make a hypothesis first

Guess: how does the body solve this problem?

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

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?
