Step 3: Make a Hypothesis (claim)
Evidence for a conclusion (claim) comes from...
Engineering Design Process
Step 2: Generate Concepts
Step 6: Conclusion (Final Claim)
Step 2B: Do Research
Step 1: Make observations about the natural world
Step 2A: Ask a Question to Research
Iterative
Evidence for a conclusion (claim) NEVER comes from...
Scientific Method
The controlled variable for "How does the lever length effect the speed of the car"
Step 5: Analyze the Results of the Lab
Step 4: Perform an Experiment to answer the question
The independent variable for "How does the lever length effect the speed of the car"
The dependent variable for "How does the lever length effect the speed of the car"
Process that repeats itself over-and-over again
Changed the lever length on a mousetrap car and time which one went faster: longer or shorter lever (Step of the Scientific Method)
How does the lever length effect the speed of the car as it travels 2 meters (Step of the Scientific Method)
My opinions on what I think the answer is
Data or observations only from an experiment or the environment
mass of the car
Stepwise iterative process used to innovate a mousetrap car
After performing the lab we examined the data we collected to see which lever length went faster over 2 meters (Step of the Scientific Method)
Learned about the differences between mass and weight by reading/watching videos and discussing (Step of the Scientific Method)
We reviewed what we learned by watching and recording data from our previous experiments on mousetrap cars (Step of the Scientific Method)
Answered the question "How does the lever length effect the speed of the car" before performing the experiment (Step of the Scientific Method)
Stepwise iterative process used to research how the mousetrap car works
When we performed the lab on Lever Length vs. Speed this is research for what step of the engineering design process
speed of the mousetrap car
lever length
Answered the question "How does the lever length effect the speed of the car" based on the lab results only (Step of the Scientific Method)
