Plant Growth
• Examine cards that were given to your group.
• Discuss any similarities and differences• See if you can make any connections• All plants are growing…so what is
different about them?

Homework Follow-Up
• Take out the article, Functions and the Volume of Vases and turn to Figure 1
• In your table group, discuss verbal descriptions for each of the graphs
• Compare answers with another table group

Filling a Container
• Examine the container that has been given to your group.
• Do you expect the relationship between the height of the water in the container and the amount of water in the container to be linear or non-linear?

Filling a Container
On your handout…• Sketch a picture of your container.• Sketch a graph that represents how you
think the height of the water will change with each cup poured in.

Filling a Container
Now for the experiment…• Add a fixed amount of water to the
container. Measure the height of the water and record the data in the table given.
• Repeat this process until the container is full.

Filling a Container
• Accurately graph the data collected on grid paper.
• Compare the sketch of your predicted graph with the actual graph that you obtained from your data.

Filling a Container
• Work with your group to draw your graph on poster paper.
• Draw a cross section of the container next to the graph.
• Prepare to share your graph with the whole group

Filling a Container
Follow-Up Questions• Is the relationship linear? Why or why
not?• What is the domain and range of the
function?

Filling a Container
Follow-Up Questions• Suppose the bulges of your container
were replaced by narrow parts, and the narrow parts were replaced by bulges. Draw the new container and a graph that would represent the height of the water as a function of the number of times the water was added.
