ASSIGNMENT

If you have already written the definition in your notebook, jump directly to part 2.

Part 1 : Search and write the definition of the vocabulary in your notebook

Part 2 : Go to https://www.explorelearning.com/index.cfm?method=cResource.dspView&ResourceID=630

Don’t forget, if the time’s up, you can still have access to the simulation by using an incognito window in your browser. If it still does not work, try another browser on your computer.

1. Explore the simulation. Try to understand how it works by clicking on every buttons.
2. Complete the Gizmo Warm-up below. Write your answer in your notebook.

Gizmo Warm-up: Using the Graphing Skills Gizmo

1. The Graphing Skills Gizmo starts with a bar graph on the right and a data set on the left. Practice using the Gizmo by doing the following:
   •   Write a title.
   •   Label the vertical and horizontal axes.
   •   Change the scale of the vertical axis.
   •   Drag the bars up and down.
2. Use the Graph type dropdown list to select other kinds of graphs. Practice with each type of graph:
   •   On the Line graph drag the points up and down.
   •   On the Pie chart change the size of each slice by dragging the edges.
   •   On the Scatter plot drag points from the data table to the graph.
