FREE MATH LESSON - “Using a Graph to Find Area”

by Science Stuff

7th - 10th Grade

Purpose: In this activity, you will be using a sample of ordinary poster board with uniform thickness to study area. Since the thickness is constant, you can measure the mass and area of rectangular poster board samples and graph the data to find a relationship between mass and area (mass/area). Using the graph, you will then be able to find the unknown area of an irregularly shaped sample of poster board. This is an activity that can be used to teach basic graphing skills as well as the use of basic pieces of lab equipment - the ruler and the balance.

Materials needed: Balance , 4 samples of poster board of regular shape, 1 irregular sample, graph paper, ruler, pencil.

Your download will include Title, Purpose, Introduction, Materials, Safety Precautions, Procedure, Analysis Questions, Student Data Pages, Answers to all Questions, and Teacher Preparation Notes.
