Engineering and Design.
๐ฏ Your mission
Predict it first. Then prove yourself right (or wrong).
โก The twist
The first design always fails. That's the point.
Mind = Blown
๐ ๏ธ The first computer bug was a literal moth stuck inside a machine in 1947.
Make a hypothesis first
Guess: what's the weakest part of this build?
What You'll Learn
The scientific method is a systematic approach to investigating questions. It involves making observations, forming hypotheses, conducting experiments, analyzing data, and drawing conclusions.
Key Words
- hypothesis
- variable
Materials Needed
- paper clips
- rubber bands
- string
Safety First
- Dispose of materials properly after the experiment.
- Handle glass items carefully to avoid breakage.
- Do not mix unknown chemicals together.
Steps
Read about Engineering and Design and write down three key facts.
Design and build a bridge from newspaper and tape that can hold a textbook. Test it and redesign to make it stronger.
Observe what happens and describe it in detail.
Record your observations in your science journal with measurements and descriptions.
