InterActions in Physical Science

The class then tried to decide on a single best value for its measurement. They wondered what to do about team C’s value because it was so very different from all the other measurements. Team C admitted they were careless in how they made their measurement.

Do you think team C’s measured value should be included in determining the best value for the class? Why or why not?

Participate in a class discussion to talk about the answers to the questions.

My Ideas

The key question for this activity is:

When you measure something, can you obtain an exact value?

1. Based on what you learned in this activity, answer the key question.
2. Suppose you repeated the experiment in this activity. What would you do differently, so you could report the best value for the time?

Scientists have agreed on ways to answer questions like these, based on performing many experiments. The ways that scientists make and interpret measurements are given in How to Make and Interpret Experiment Measurements in the Appendix.

Follow along as your teacher reviews the information with you.
