Read the lab procedure for a controlled experiment that looks at the effect of heat on the circumference of bicycle tires.


Step 1: Pump up six identical bike tires to the recommended air pressure.

Step 2: Place three tires under heat lamps, and keep the other three tires at room temperature.

Step 3: After four hours, measure the circumference of each tire.

Step 4: Record your results in the table.

Step 5: (?)


Which step should be next in this procedure?

Verified Answer :

Explanation :

To start any lab work initially, we have to know the theory behind the experiment. After then the experiment should be started. At the end, the readings must be taken carefully and some conclusion can be drawn.

Some of the steps are given :

Step 1: Pump up six identical bike tires to the recommended air pressure.

Step 2: Place three tires under heat lamps, and keep the other three tires at room temperature.

Step 3: After four hours, measure the circumference of each tire.

Step 4: Record your results in the table.

The fifth step should be :

Step 5: Write the result or conclusion that shows what you have done during the entire experiment.

Answer:

Step 5: Draw conclusions and write the final result

Explanation:

In controlled experiment, after all the steps of the experiment, the observations are written in the table.

In the given lab procedure for the effect of heat on the circumference of bicycle tires.  In step 5, the recorded result must be analysed and conclusion must be drawn and final result must be written.
