# Lesson 7 Introduction to Liquid Volume

• Let’s learn about liquid volume.

## Warm-up Notice and Wonder: The Bowl and the Jar

What do you notice? What do you wonder?

## Activity 1 Liquid Volume Estimation Exploration

Your teacher will give you two containers labeled “A” and “B,” and another container labeled “unit.”

1. How many units do you think container A will hold?

Record an estimate that is:

too low

too high

2. How many units do you think container B will hold?

Record an estimate that is:

too low

too high

3. Use the unit container to compare the liquid volume that containers A and B hold. Which container holds the greater volume? How do you know?

## Activity 2 Liquid Volume in Liters

How many liters of water will fit in the large container?

Record an estimate that is:

too low

too high

## Problem 1

For each item, decide whether it holds more than a liter, less than a liter, or about a liter.

1. a bathtub

2. a cup

3. a swimming pool

4. a small pot for a plant
