After rotating through the stations, answer these questions with your group.
- Did more cubic inches or cubic centimeters fit in the cardboard box in Station 1? Why?
- Did it take more feet or meters to measure the indicated length in Station 2? Why?
- Based on your work in Station 3, do you think it would take more quarts or liters to fill a bucket? Explain your reasoning.
- Use the data from Station 4 to put the units of weight and mass in order from smallest to largest. Explain your reasoning.
- Based on your work in Station 5:
- About how many teaspoons of salt would it take to fill the graduated cylinder to 100 milliliters?
- If you poured 15 teaspoons of salt into an empty graduated cylinder, about how many milliliters would it fill?
-
