In your IAN start a new unit called UNIT 7: Graphing Biological Trends & Systems On the first page of this new unit, list the following terms and write 3 sentences using at least 9 of these terms. Variable Line Graph Chart Bar Axis Horizontal Vertical Plot Trend Data

2
Graphing Review, Types of Graphs and How to Read a Graph

3
Graphing is a method of taking a large amount of information and presenting it in an easily readable format. You must be able to identify, create and read a simple 2-D graph. You must understand and be able to determine the different variables involved in creating a 2-D graph. You must be able to compare and contrast the different types of variables and different types of graphs in this unit.

4
In your IAN notebook, you will create the a foldable to help you create and read graphs in this unit. Take the 8½” x 11” sheet of paper you are given and turn it Landscape Style as shown.

5
Fold the left and right side of the paper into the middle like you are creating “Doors”.

6
Flatten your page out again, and on the middle top paste the graph you were given.

7
Divide the inside of each door into 3 sections.

8
Write the follow terms at the top of each box on the doors. After writing each term, define these terms in the box. D ependent Variable R esponse Variable Y - Axis I ndependent Variable M anipulated Variable X - Axis

9
Dependent Variable – the possible outcome of the experiment; the effect. Response Variable – What did I measure? What was the effect of the change? Y – Axis = The Vertical Axis on a graph. Manipulated Variable – What did I change in the experiment? What will happen if this changes? Independent Variable – the variable that you have control over, what you can choose and manipulate. X – Axis = The Horizontal Axis on a graph.

10
Label your graph paper as shown below. Write the bulleted list directly under the graph. Also show the Y – Axis and X – Axis on the graph. D ependent Variable (D.V.) R esponse Variable Y - Axis I ndependent Variable (I.V.) M anipulated Variable X - Axis Graph Title Name of D.V. goes here. Name of I.V. goes here. Start each axis with zero. Each axis should be divided into even increments. Label all parts of the graph. Label the units of each axis. Write the list below here! Y - Axis X - Axis

11
Write the term Control Variables and its definition at the bottom of the middle section as shown. D ependent Variable (D.V.) R esponse Variable Y - Axis I ndependent Variable (I.V.) M anipulated Variable X - Axis Graph Title Name of D.V. goes here. Name of I.V. goes here. Control Variables: All variables that could affect the experiment, but are taken out of the equation because they remain constant. (Must stay the same!) Write the Term and Definition below here! Start each axis with zero. Each axis should be divided into even increments. Label all parts of the graph. Label the units of each axis.

12
Close the doors to your foldable and draw the lines shown on the two doors to separate them into 3 sections each. Then write the letter shown on each section. DRY-MIX is the acronym we will use to remind you about graphing! D R Y M I X This side of the foldable gives the definition for the Dependent Variable, explains it is the Response to a change in the experiment, and shows it is located on the Y-Axis. This side of the foldable gives the definition for the Independent Variable, explains that it Manipulates a change to the experiment, and shows it is located on the X-Axis.

13
Now paste your foldable with the DRY-MIX side up in your IAN. You should be able to open the doors and read everything that is inside! D R Y M I X

14
A Y vs. X graph means that the variable Y depends on the variable X to determine the location of each point on the graph. We call this a graph of “Y as a function of X”, which means “Y depends on X”. Now let’s look at the types of graphs you can create with this basic graphing template! In each example, write down the Dependent Variable and the Independent Variable on your copy.

19
In your IAN, you will create a graph of your own test scores for this year in IPC. First, determine what variables you will need to create your graph. What is the dependent variable? What is the independent variable? Next, determine the scale and divisions for each of your axes. (HINT: You can use the lines in your notebook to help you.) Last, draw your graph in your notebook. Label and scale your axes, plot your data points, and write the title for your graph. (HINT: Leave room for future test scores so you can update your graph.)

20
What does this graph tell you about your test scores in this class? How does this information help you in this class? How does this information help your teacher with your instruction? How does this information help your parents with your learning? What else can this information tell you?

21
A scientist plants two rows of corn for experimentation. She puts fertilizer on row 1 but does not put fertilizer on row 2. Both rows receive the same amount of water and light intensity. She checks the growth of the corn over the course of 5 months. What is a constant in this experiment? A. Amount of water B. Corn without fertilizer C. Corn with fertilizer D. Plant height Justify your answer: _________________________________________________
