Method Steps and Choosing Equipment
A class is testing how the height of a ramp affects how far a toy car rolls. The steps below are out of order. Number them 1 to 8 so another student could follow the method and get the same results, then answer the equipment questions.
- 1.Number this step: Change the ramp to the next height, keeping everything else the same, and repeat the runs
- 2.Number this step: Write the question and a hypothesis about how ramp height will change the distance the car rolls
- 3.Number this step: Repeat the run twice more at the same height and record all three distances in a table
- 4.Number this step: Calculate the mean distance for each ramp height
- 5.Number this step: Set the ramp to the first height and measure that height with a ruler
- 6.Number this step: Plot a graph of ramp height against mean distance and write a conclusion based on the evidence
- 7.Number this step: Measure the distance from the end of the ramp to where the car stops
- 8.Number this step: Release the car from the top of the ramp without pushing it
- 9.A stopwatch reads to 0.01 s and a wall clock to 1 s. Which gives the more precise measurement?
- a) the stopwatch
- b) the wall clock
- 10.Which piece of equipment measures 25 mL of water most precisely: a beaker or a measuring cylinder?
- a) beaker
- b) measuring cylinder
- 11.What safety equipment must be worn when heating liquids in the laboratory?
- 12.Which instrument measures how long something takes?
