= **The assignment.** =
 * On MyOn read the following: **
 * **Lions and Tigers and Graphs! Oh, my!**
 * 1) **Read the book all the way through once and take the quiz at the end.**
 * 2) **Read the book through again slowly to find the answers to the questions below.**
 * 3) **Write the answers in complete sentences next to each question.**


 * After reading the story, answer these questions: **
 * 1) What is a graph? A graph is a way to organize different kinds of data.
 * 2) What is a **pictograph**? a graph shown through pictures
 * 3) What is a **tally chart**? It's a chart that shows the frequency of something happening
 * 4) What does **compare** mean? to
 * 5) What are the **axis** on a graph? the up/down lines on the bottom or the side
 * 6) Which is the **x axis** and which is the **y axis**? X axis is the one on the bottom that goes left to right, Y axis is the one that goes up and down on the left.
 * 7) What does the **title** of a graph tell about the graph? It tells you the purpose of why the data was collected and tells you what data is collected.
 * 8) What is another name for a **circle** graph? Pie chart
 * 9) What does the **key** of a graph tell about the graph? It color-coordinates things with colors, so its easy to identify which data is which.
 * 10) What is a **poll**? Its a survey of options
 * How do you know which type of graph to make? **
 * 1) What is the purpose of a **line graph**? To show the progression of something, either good or bad
 * 2) What is the purpose of a **pie chart**? To show the entire group of something.
 * 3) What is the purpose of a **pictograph** or **bar chart**? To compare one thing or a group of things to another, all with the same purpose.
 * 4) What is the purpose of a **tally char**t? To show the frequency of an event.
 * Science Graphs **
 * 1) Write a description of the data you are collecting for your science fair topic. I have to put a certain percentage of sugar into my control, water, and shine a laser pointer through the solution and putting the measurements through the Snell's Law equation, and have the answer compared to the other results with different percentages of sugar in the water.
 * 2) What type of graph will you create? Line graph
 * 3) Explain why you will use that type of graph. I'm going to have the y-axis the predicted range of the results and percentage of sugar in water on the x-axis, 10%, 20%, etc., and put the dot of data where specified and then 'connect the dots' and see how much it refracts inward or outwards. Each trial will be colored coded so there's no confusion of which trial's which.
