Length and Measurement Lab

Subject Area

Grade(s)

Overview

The Length and Measurement Lab will provide students with hands-on experience in measuring the length and mass of objects using the Metric System. During this lab, students will be given a set of manipulatives (colored rods) and asked to find the length in centimeters. Then, they will convert that measurement into millimeters. The final task will require students to use a balance to record the mass in grams of each colored rod.

This learning activity was created as a result of the Girls Engaged in Math and Science (GEMS) Resource Development Project, in partnership with Dothan City Schools.

    Select and use an appropriate unit of measurement for a given attribute (length, mass, liquid volume, time) within one system of units: metric - km, m, cm; kg, g, l, ml; customary - lb, oz; time - hr, min, sec.

    Knowledge

    Students know:
    • units of measures for given attributes vary in size and are related by multiplicative comparison.

    Skills

    Students are able to:
    • Select and use appropriate units of measure for a given attribute.
    • Convert larger units of measure to smaller units of measure within the same measurement system.
    • Record measurement equivalents in a two-column table.

    Understanding

    Students understand that:
    • There is an appropriate unit of customary measurement and metric measurement for a given attribute.
    • Multiplicative relationships exist between customary units of length, mass, liquid volume, and time.
    • Multiplicative relationships exist between metric units of length, mass, liquid volume.

    Learning Objectives

    Learning Objectives

    • Students will measure the length and mass of objects using the metric system and record the data in a table.
    • Students will use their understanding of the metric system to convert centimeters into millimeters.

    Activity Details

    Students will work through the Length and Measurement Lab Slideshow throughout the course of the activity.

    Engagement/Background:

    1. The teacher will use slides 2-6 to introduce length and mass and how to read a ruler in centimeters and read a digital balance. 

    Independent Work:

    1. Students will be provided with 7 colored rods, a ruler, and a digital balance (1 per group, depending on how many balances).
    2. They will use the ruler to measure each colored rod and record the length in centimeters on the data table. Students will convert this measurement into millimeters and record it on the same table. The data table can be printed from the slideshow and copied for each student, or the teacher can share the slideshow with students, and they can type their responses on the slide. Students will use the balance to determine the mass of each colored rod and record the result on the same data table.
    Assessment Strategies

    Assessment Strategies

    The students will be assessed by completing the length and mass problems on slides 8-10 of the Length and Measurement Lab Slideshow. The students can answer the questions on paper or the teacher can share the slideshow with the students, and students can type their responses on the slide.

    Acceleration

    Students can use the following online activity to enhance their skills in converting measurements in the metric system.

    Intervention

    Students struggling to correctly use the measuring tools will be put into a teacher-led small group.

    Approximate Duration

    Total Duration

    16 to 30 Minutes

    Background and Preparation

    Background / Preparation

    Students should have a basic understanding of a ruler and how they are used to measure the length of objects. The teacher should provide background knowledge on the scientific base unit used to report length and mass (meters and grams). The instructor can use slide 4 to explain mass and how to use a balance to measure the mass of an object.
