__Essential Standards:__

Social Studies:

4.G.1.2 Explain the impact that human activity has on the availability of natural resources in North Carolina. <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">4.G.1.3 Exemplify the interactions of various peoples, places and cultures in terms of adaption and modification of the environment.

<span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Technology:

<span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">4.TT.1.3 Use technology tools to present data and information (multimedia, audio and visual recording, online collaboration tools, etc.).

<span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Mathematics (NCSCOS): <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Objective 4.01 - Collect, organize, analyze, and display data (including linegraphs and bar graphs) to solve problems.

<span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">__Procedures:__
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Inform the students that today they will begin to learn about conservation.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Give each student a cookie and a napkin
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Have the students stand. When you give a signal, they are to begin eating their cookie. When they have swallowed the last bit of cookie, they should sit down. Every 20 seconds count the students that that are still standing. (Once a student sits, he/she should remain in their seats until all the students are finished).
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Have students independently construct a bar graph representing the collected information using the worksheet provided. The teacher should circulate throughout the room checking for understanding and on task behavior. Once students have completed their work, the teacher should ask for 1-2 volunteers to share their work with the class (by displaying their graph on the Elmo). Be sure to check for understanding by asking:
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">What do each of the axes represent?
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">What do the bars in your graph represent?
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Distribute a second cookie. This time students can only take a bite when you say “take a bite” (every 20 seconds). The system is the same – students sit when finished and you tally the standing students every 30 seconds.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Have students construct another bar graph using the worksheet provided.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Compare the graphs: __Graph One__ represents unlimited consumption while __Graph Two__ represents conservation.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Is Graph Two like Graph One?
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">How are they different?
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">How long did it take for all resources to be consumed
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Discuss the term “conservation.” In the second cookie – eating exercise, conservation was practiced.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Does conservation result in preservation? Why not?
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">What good does it do to conserve?
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">What happens to the life expectancy of the resource when conservation is practiced?
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Provide the students with the following writing prompt. Students are expected to respond in with no less than two paragraphs:
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">How could conservation affect the natural resources of North Carolina?

<span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">__Differentiation:__ <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">__﻿__ <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">__Assessment:__
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">﻿ Although the bar graph will have been introduced in math, the outline and some of the labels have been added for students who are still picking up the concept.
 * <span style="color: #000000; font-family: 'Times New Roman',Times,serif; font-size: 110%;">For all students, present information in multiple fashions: say it, demonstrate it, write it.
 * <span style="color: #000000; font-family: 'Times New Roman',Times,serif; font-size: 110%;">Since some students may be unfamiliar or out of practice with bar graphs the teacher should provide clarification and aide if need be.

<span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Written work will be assessed using Rubric for Written Work
