1. Scientific Method

2. steps Question Background research/ observations Hypothesis Experiment
Analyze data
Conclusion
Communicate results

3. Controls Controlled Variables stay the same throughout the experiment.
Control group- stays the same; compare different independent variables to it
Example: How does the amount of water affect plant growth?
C.V. = type of plant, location of plant, type of water
C.G. = plant with no water

4. Independent variable
ONE thing that I change in the experiment. What do I do different each time I conduct the experiment? Example: How does the amount of water affect plant growth? I.V. = amount of water

5. Dependent variable
What’s observed and changes depending on the independent variable Example: How does the amount of water affect plant growth? D.V. = plant growth

6. Engineering design process

7. Steps Identify the problem Research Design Build prototype Test
Evaluate
If it doesn’t work, go back to step 3
If it works, communicate results
