Matching Pairs Flashcards - MT Car Expt: Lever Length vs. DistanceOnline version assignment by Benjamin D Morgan 1 Dependent Variable 2 Step 3: Make a Hypothesis (claim) 3 Iterative 4 Evidence for a conclusion (claim) NEVER comes from... 5 Step 2A: Ask a Question to Research with a lab 6 Controlled Variable 7 Step 2B: Do Research 8 Step 1: Make observations about the natural world 9 If I think my data from the experiment is wrong then... 10 Step 6: Conclusion (Final Claim) 11 Independent Variable 12 Evidence for a conclusion (claim) comes from... 13 Step 4: Perform an Experiment to answer the question 14 If I think my data from the experiment is wrong then I NEVER 15 Step 5: Analyze the Results of the Lab Ignore the evidence (experimental data) and write what I think the correct answer is Looked at our experimental results of which car went farther: the shorter or longer lever I write a final claim based on the evidence anyway OR redo the lab again How does the lever length effect the distance of the car Reviewed the observations we made during our first experiment (how the mass effected the speed of the car) Learned about normal force, what it is, and how it acts on the MT Car A process that repeats a series of steps over and over Answer the question "How does the lever length effect the distance of the car" based only on our previous knowlege before performing this experiment Changed the lever length on a mousetrap car and then saw which went farther by measuring it Answer the question "How does the lever length effect the distance of the car" based only on the results of the lab we did with this assignment My opinions on what I think the answer is The variable that is made different in an experiment The variable that we measure in an experiment The variable that we keep the same in the experiment or it will effect/throw off the results Data or observations only from an experiment or the environment
