Mr. Nelson         Biology I         50 Minutes

Objective: The student will identify the particular uses for bar graphs, line graphs, and pie charts (Biology, 1.d)

Bell Work: Review of the previous days lesson.

Materials: Paper, writing utensil, white board markers, graphing worksheet.

Set: Instruct the students to write down each of the following, pause after each one: 4 months of the year. The numbers 1 through 5. Their family tree. A mock bracket. Call on students to come up and put their lists on the board. Notice how each bit of information is written in a different way. Depending on our data, we may need to use a different technique to best model the data. Usually with numbers, we write them up to down. Many people write the months from left to right. Family trees are best represented their own unique way… etc. In the same way, data we collect in science are best represented in different ways. There are many ways to visually represent data – it all depends on what you are doing. Today we will be talking about three main ways to represent data – state objectives.

Procedure:

1.    Overhead on different graphs or simply go over how to draw each graph on the whiteboard. 

    a.    Cover the placement of the independent, dependent, key, title

    b.    Cover why each graph is used (bar = comparison, line = time relationship, pie = percentages

2.    Cover the “brief narrative” What is a brief narrative? When would you use it?

3.    Assignment – worksheet on creating graphs. Answer any questions the students have.

4.    Collect assignment.

Closure: Verbal review of graphs. Independent variable, dependent variable, etc. Remember don’t let graphs confuse you because they are new. This is especially helpful for ACT and state tested material. Field any questions, preview the next lesson.

Assessment:

Objective: The student will identify the particular uses for bar graphs, line graphs, and pie charts (Biology, 1.d)

Formal: The student will complete a short worksheet (M) in which they will demonstrate knowledge on the uses for bar graphs, line graphs, and pie charts (C). The worksheet will be graded and recorded in the grade book (D).

Informal: The teacher will verbally review (M) with the students as they progress through the lesson on bar graphs, line graphs, and pie charts (C).
