“Number of Tadpoles in Pond”

Adapted from www.biologycorner.com

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. 5. 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 1992. 3.  Between 1992 and 1993, populations of tadpoles _________________.4.  Tadpole populations __________________after 1993.5.  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.

Design a line graph of the data and then answer the following questions.

Analysis QuestionsWhat 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?

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!)

Station 8

Questions:What is the dependent variable? What is the independent variable? What was the average thickness

of the annual rings of 40 year old trees in Forest A? Forest B?

Based on this data, what can you conclude about Forest A and Forest B?
