__Title__: Constructing and Analyzing Data

__Description__:

In this lesson, students will construct a line graph. The students will determine the dependent and independent variables of the experimental data and analyze their relationship.

__Duration__: 39 minutes

__Learning Objectives__:

Students will learn how to plot data into a line graph. Students will analyze an experimental data and explain the components of a line graph.

__Standard:__

Performance Indicator MST1.C.SI3A: Students use various means of representing and organizing observations (e.g., diagrams, tables, charts, graphs, equations, matrices) and insightfully interpret the organized data.

__Grade Level(s)__: 9 or 10

__Materials__: graph paper, pencil, ruler, laptop, projector

__Step by Step Procedure__: a. Mini-Lesson What are the different kinds of graphs?

Describe the following graphs that you’ll see on the slides.

b. Learning Task

Read carefully the experiment on The Effect of Temperature on Water Flea Heart Rate. Click the worksheet

Explain the components of a line graph and the difference between dependent and independent variables.

Provide each student a graph paper and a pencil. Let them plot the data into a line graph and analyze the variables. They should answer the four questions in complete sentence(s).

Students worksheet

Have the students show their graph to their pair.

c. Summary

What does the x-axis represent in a graph? How about the y- axis?

What does the graph tell you about?
