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