Compare the children's recorded measurements after they have completed the record sheet. Tell the children that one measuring worm equals 5 inches, so if an object is 2 measuring worms long you would count by 5 twice to get the correct number of inches. Have the children count along as you count by fives the number of inches the object measured. A funnel Bucket or large pan Suggested Books Allen, Pamela. Mr. Archimedes' Bath .
Procedure Show the children a container that is a quart and a container that is a gallon.
Ask the children which container would hold more and which would hold less. Explain to the children that just as an inch is used as a standard unit of measurement for length, a quart is used to measure the volume of something. Volume measures how much space something takes up. Have the children get into groups of four. Write each group's predictions on the board.
