Engineering and Design.
๐ฏ Your mission
Set it up. Test it. Be amazed.
โก The twist
Every solution creates a new problem. That's good โ that's the next project.
Mind = Blown
๐ The Saturn V rocket burned 20 tons of fuel per second at liftoff.
Make a hypothesis first
Predict: which design will hold the most weight?
What You'll Learn
Models help scientists represent complex systems. Physical models (like a globe), mathematical models (like equations), and computer models all simplify reality to make it easier to study.
Key Words
- experiment
- data
- observation
Materials Needed
- plastic wrap
- cardboard
- tape
Safety First
- Do not mix unknown chemicals together.
Steps
Review the background information on Engineering and Design before starting.
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?
Look for patterns in your observations.
Make a graph or chart showing your results.
