Human Impacts on Earth.
๐ฏ Your mission
Play with the model. Break it. Understand it.
โก The twist
Every species solves the same problem differently.
Mind = Blown
๐ณ Trees can talk to each other through underground fungus networks.
Make a hypothesis first
Before you watch: what do you think it'll do?
What You'll Learn
Engineers must consider constraints (limitations like cost, time, and materials) and criteria (requirements the solution must meet) when designing solutions to problems.
Key Words
- criteria
- iteration
- wavelength
Steps
Read about Human Impacts on Earth and write down three key facts.
Conduct a design challenge: build a car powered only by a balloon. Measure how far it travels and iterate on your design at least twice.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
Check Your Understanding
