# Creating and Interpreting Graphs Webquest for Mr. McCalls's Intro to Physics and Intro to Chemistry Classes

## Introduction

This webquest is provided so that students can be allowed to have more practice with graph creation and interpretation. The webquest will involve filling in answers into a word document by finding them within this website plus creating graphs from information gained from other students in the classroom. Click on the Task tab to better understand what is expected from this webquest.

## Task

The task of this webquest will require the completion of a microsoft word document by searching this website to find the answers to the questions on the document. During the completion of the word document students will write in notes, answer questions, and ask other students questions to obtain data for creating graphs. After the microsoft document is completed the students will create a bar graph, line graph, and circle graph. Please, click on the Process tab next to begin the webquest and follow the instructions. Good Luck!

## Process

- Go to my website www.physcimhs.weebly.com by clicking on the following link My Website
- Click on
**Intro to Physics** - Click
**Chapter 1** - Download the webquest on the page entitled
**"Creating and Interpreting Graphs Webquest"** - Open the document, Print it, and begin reading the instructions to complete the document
- Make sure you staple the pages of the document together.
- Follow the instructions on the document to answer the questions present in the document (The answers for the document will be found within this webquest as follows)

**Scientists and Data:**

Scientists use **Charts, Tables, and Graphs **to organize their data when reporting results for Scientific Experiments.

The three different types of graphs used by Scientists are a Circle Graph, Line Graph, and a Bar Graph.

The **Circle Graph** is mainly used for comparing the relative parts of something to a whole, such as the percentage of people who vote during presidential elections and percentage of those who do not vote. The following is an example of a circle graph:

The **Line Graph** is used for determining the relationship between two variables, such as whether or not studying for

an exam affects the grade obtained. The following is an example of a line graph:

The **Bar Graph** is used for comparing variables to one another, such as comparing whether Tennessee or Kentucky have the highest number of people living within the border of the state. The following is an example of a bar graph:

The two variables placed on graphs are the **Independent Variable** and the **Dependent Variable**. The Independent Variable is always placed on the x-axis. The Dependent Variable is always placed on the y-axis.

When creating any graph you always label each axis with a title and units and provide a title for the graph.

When a change in the Indepdent Variable involves the same change in the Dependent Variable the relationship is called a **Direct Proportion**. The product of the two variables in a Direct Proportion is always constant. The **Temperature and Pressure of a Gas** is an example of a Direct Proportion because an increase in one makes the other increase. The following is an sketch of a Direct Proportion:

When a change in the Independent Variable involves the opposite change in the Dependent Variable the relationship is called an **Inverse Proportion**. The **Pressure and Volume of a Gas** is an example of an Inverse Proportion because the increase in one cause the other to decrease. The following is a sketch of an Inverse proportion:

8.Turn in the webquest to Mr. McCall when you have finished filling in the document and created the appropriate graphs.

## Evaluation

Your Grade for this assignment will be based on your completion of the document and the creation of one line graph, one bar graph, and one circel graph.

Make sure that you turn the webquest document in to Mr. McCall, with all the required parts, to get the highest possible grade for this assignment.

Follow on to the Conclusion Tab of this Website to end your assignment.

## Conclusion

Congratulations! You have finished the Creating and Interpreting Graphs Webquest. You have done a Fantastic Job. Make sure you turn in the document to Mr. McCall.

## Credits

All creation credit for this Webquest goes to Mr. McCall.
