You want An unusual in tf2 Do this question!Have 2 toy cars a stop watch. Put a line of tape at the starting line and finish line put a car on the start line have your stop watch push the car and time it, do that a second time with the other toy car do that 3 times for each car, record the time it took for the car to get to the finish line for each car, so (EXAMPLE:) car A took 4.362 seconds to get to end line car B took 3.685. 1. Write your hypothesis here.

2. What is the independent variable (the variable that was changed) in this investigation? How was it measured?
Include the units in your answer.

3. What was the dependent variable (the variable that changed because of the independent variable) in this
investigation? How was it measured? Include the units in your answer.

4. How many trials did you perform in this investigation?

5. Calculate the average time for Vehicle 1 from the information in your data table. Show all work.

6. Calculate the average time for Vehicle 2 from the information in your data table. Show all work.

7. Calculate the average speed for Vehicle 1 from the information in your data table. Show all work, including the
formula used.

8. Calculate the average speed for Vehicle 2 from the information in your data table. Show all work, including the
formula used.

9. Write an equation to represent the relationship between the independent and dependent variables in this
investigation.

Conclusion:
10. Make a conclusion based on the data from your experiment. Compare your conclusion to your hypothesis.
Did your experiment support your hypothesis? Consider whether your conclusion is the only explanation for
the data collected or if there are alternate explanations. Make sure to mention any scientific laws or theories
that would apply.

Follow-up Questions:
1. If your experiment did not seem to match the expected results, what did you learn from the experience?

11. Instantaneous speed is the rate of motion of an object at a particular moment in time. What change(s) to the
experimental procedure would be necessary if you wanted to gather data on instantaneous speed?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
