Speedskating

We're Sarah, Lisa, Ned, and Eric, and we're short-track speedskaters who want to melt the competition! We know that every fraction of a second counts, so we can't slow down at all while racing. That's why we're investigating how we should perform our turns: Should we enter the turn in a tight, medium, or wide radius to maintain speed?

How would you investigate this question?
What equipment will you need to measure a skater's speed around a turn? Develop a way to set up a test area on an ice rink. Think about the number of trials you should have the skaters do in order to get a meaningful result. Describe your ideas in your notebook. Then discuss them with your teacher, or go to Speedskating to learn how Sarah, Lisa, Ned, and Eric did their speedskating investigation.
