Station 1 The verbs in the box on your paper can be used to describe changes commonly seen on graphs. Examine the words. (Look them up if you don’t know what they mean.) 1. Circle the verbs that mean to go up. 2. Underline the verbs that mean to go down. 3. Put a star next to the verb that means to go up and down. 4. Use an arrow to indicate the word that means to reach its highest level Put a triangle next to the word that means to stay the same for a period of time. ___________________________________________________________ Use the “Number of Tadpoles in Pond” graph and the words in the box to help you complete some of the sentences. In some cases, there is more than one correct answer. 1. In the year 1990, tadpole populations began to ____________ rapidly. 2. Tadpole populations reached a ______________________ in Between 1992 and 1993, populations of tadpoles _________________. 4. Tadpole populations __________________after Between 1995 and 1999, populations __________________________. 6. How many tadpoles were in the pond at its highest point? ___________ 7. How many tadpoles were present in the pond in 1998? ___________ 8. Between 1998 and 1999, tadpole populations ____________ somewhat.

In what year did Ms. Smith and Mr. Jones sell the same number of houses? Using Graph #2 A. What is the dependent variable? B, What happened to the plant between weeks 4 and 5? C, Between which two weeks did the plant show the most growth? Using Graph #3 A. What is the number of deer in 2000? B. How often are deer being counted? C. Do you think the title of the graph is valid? Why/Why not? Using Graph #4 A. Tell what the bar graph measures. B. On average, how many hours a day is the computer used on weekdays? C.

**Station 3 Tiger Shark Population School Subject Survey**

The population of tiger sharks off the coast of Florida was recorded over several months. Graph the tiger shark populations below using a line graph. Your graph paper has been set up for you. ________________________________________________________________________________________________ School Subject Survey Bob asked classmates what their favorite school subject is. Make a bar graph of the results shown below. Your graph paper has been set up for you. Favorite Subject Number English 12 Science Math History P.E. Resource 23 18 9 2 10

**Station 4 Analysis Questions What is the dependent variable? (y-axis)**

pH of water Number of tadpoles 8.0 45 7.5 69 7.0 78 6.5 88 6.0 43 5.5 23 Design a line graph of the data and then answer the following questions. Analysis Questions What is the dependent variable? (y-axis) What is the independent variable? (x-axis) What is the average number of tadpoles per sample? What is the optimum water pH for tadpole development? Between what two pH readings is there the greatest change in tadpole number? How many tadpoles would we expect to find in water with a pH reading of 5.0?

**Average thickness of the annual rings in cm.**

Station 8 Age of the tree in years Average thickness of the annual rings in cm. Forest A Forest B 10 2.0 2.2 20 2.5 30 3.5 3.6 40 3.0 3.8 50 4.5 4.0 60 4.3 The thickness of the annual rings indicate what type of environmental situation was occurring at the time of its development. A thin ring, usually indicates a rough period of development—lack of water, forest fires, or a major insect infestation. On the other hand, a thick ring indicates just the opposite. Construct a two-line graph of the above data. Answer the questions that follow. (Use 2 colors!)
