Skills
- plan (fair tests to analyze a model or prototype) #dok2
- carry out (controlled tests with attention to variables and failure points) #dok3

Learning Targets
- I can plan a test where only one variable is changed at a time. #dok2
- I can carry out a fair test on a model or prototype to observe how it works. #dok3
- I can identify which parts of my model or prototype did not work as expected (failure points). #dok2
- I can suggest ways to improve a model or prototype after analyzing test results. #dok3
- I can control variables during an investigation. #dok2
Big Ideas
- Engineering design involves testing and refining prototypes through fair, controlled experiments.
- Testing models and prototypes with controlled variables helps identify improvements for better solutions.
Essential Questions
- Why is it important to control variables when testing a model or prototype?
- How can we set up a test to make sure it is fair?
- What can we learn from failure points in our prototypes?
- How do fair tests help us improve our designs?
- What steps should we take after a test shows that part of a prototype does not work as expected?
