Name Estimate and Measure Liquid Volume Essential Question How can you estimate and measure liquid volume in metric units? Unlock the Problem Lesson 10.7 Measurement and Data 3.MD.A.2 MATHEMATICAL PRACTICES MP4, MP5, MP6 Hands On Liquid volume is the amount of liquid in a container. The liter (L) is the basic metric unit for measuring liquid volume. Activity 1 Materials 1-L beaker 4 containers water tape 950 850 750 650 550 450 350 250 METRIC 1000mL 900 800 700 600 500 400 300 200 STEP 1 Fill a 1-liter beaker with water to the 1-liter mark. STEP 2 Pour 1 liter of water into a container. Mark the level of the water with a piece of tape. Draw the container below and name the container. STEP 3 Repeat Steps 1 and 2 with three different-sized containers. Container 1 Container 3 Container 2 Container 4 Math Talk MATHEMATICAL PRACTICES 8 Draw Conclusions What happens to the liquid volume when you pour the same amount of liquid into different sized containers? 1. How much water did you pour into each container? 2. Which containers are mostly full? Describe them. 3. Which containers are mostly empty? Describe them. Chapter 10 599
Compare Liquid Volumes Hands On A full glass holds less than 1 liter. A water bottle holds about 1 liter. A fish bowl holds more than 1 liter. Activity 2 Materials 1-L beaker 5 different containers water STEP 1 Write the containers in order from the one you think will hold the least water to the one you think will hold the most water.,,,, STEP 2 Estimate how much each container will hold. Write more than 1 liter, about 1 liter, or less than 1 liter in the table. STEP 3 Pour 1 liter of water into one of the containers. Repeat until the container is full. Record the number of liters you poured. Repeat for each container. Container Estimate Number of Liters STEP 4 Write the containers in order from the least to the greatest liquid volume.,,,, Math Talk MATHEMATICAL PRACTICES 1 Evaluate Was the order in Step 1 different than the order in Step 4? Explain why they may be different. Image Credits: (tr) PhotoDisc/Getty Images 600
