Your teacher will show you two rods. Does it take more green rods or blue rods lined up end to end to measure the width of a piece of printer paper?
Station 1
Each large cube is 1 cubic inch. Count how many cubic inches completely pack the box without gaps.
Each small cube is 1 cubic centimeter. Each rod is composed of 10 cubic centimeters. Count how many cubic centimeters completely fill the box.
Station 2
Your teacher showed you a length.
Use the meter stick to measure the length to the nearest meter.
Use a ruler to measure the length to the nearest foot.
Station 3
Watch the video.
Count how many times you can fill the quart bottle from the gallon jug.
Count how many times you can fill the liter bottle from the gallon jug.
Station 4
Use the applet to record the weights of different objects in different units.

Record their weights in ounces, pounds, grams, and kilograms.
Station 5
Count how many level teaspoons of salt it takes to fill the graduated cylinder to 20 milliliters, 40 milliliters, and 50 milliliters.
Pour the salt back into the original container.
After you finish all five stations, answer the following questions with your group.
Which is larger, a cubic inch or a cubic centimeter? Did more cubic inches or cubic centimeters fit in the cardboard box? Why?
Did it take more feet or meters to measure the indicated length? Why?
Which is bigger, a quart or a liter? 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.
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?
How many milliliters per teaspoon are there?
How many teaspoons per milliliter are there?
