LESSON 8 Fill It Up

Lee Yah found two jars with unusual shapes.

Help Lee Yah make a plan to find out which jar has a greater volume.

Use a container, a graduated cylinder, an eye dropper, and some water. Pretend that the container is one of Lee Yah's jars. How can you use the graduated cylinder and the water to find the volume of the container?

  1. Draw a picture of your plan on a piece of paper.
  2. Follow your plan. What is the volume of the container?

There is more than one way to find the volume. Think of another way to use the graduated cylinder and the water to find the volume.

  1. Draw a picture of a second plan on the other side of your paper.
  2. Follow your plan. Did you get the same volume as before?
  3. Which plan do you think gave you a more accurate volume? Why?

Use the Fill It Up Lab pages in the Student Activity Book to measure the volume of at least three containers. Later you will use this information to estimate and find the volume of a Mystery Jar.
