Engineering and Design.
🎯 Your mission
Push the limits. See what changes.
⚡ The twist
Constraints make you more creative, not less.
Mind = Blown
🛠️ The first computer bug was a literal moth stuck inside a machine in 1947.
Make a hypothesis first
Before you test: how many tries until it works?
What You'll Learn
Accuracy describes how close a measurement is to the true value, while precision describes how close repeated measurements are to one another. A trustworthy result should be both accurate and precise.
Key Words
Tap a word to see its definition.
Steps
Look at the vocabulary words and write a definition for each in your own words.
Design an experiment to test a hypothesis. Identify your independent variable, dependent variable, and controls. Run the experiment and present results.
Observe what happens and describe it in detail.
Record your observations in your science journal with measurements and descriptions.
