Day 3

  1. Students will break into their groups of three to complete the experiment designed on Day 2. Be sure that the materials the students will need are available.

  2. Students will test the hypothesis and gather data for the entire hour.
  3. Collect your materials and go outside to do the experiment.
Day 4
  1. The class will discuss the data and make graphs together.

  2. Students will attempt to draw conclusions which will then be discussed in class.

  3. Additional resources for class 4

    Students will analyze the data by graphing the three columns of data versus time. For example, if the data in the table from Day 2 were collected, the graph below will be created by students. In this example, the program WORD was used to graph the data.


    graph of leaves taken per minute

    The graph gives students a visual representation of the change in number of leaves taken per minute in each ten-minute set. Students will be asked:

    • Does the number of leaves taken per minute increase or decrease with time for each trial?

    • Do the number of leaves taken in each trial increase at the same rate?

    • Why are more leaves taken with each trial?

    The first two questions will be easy for students to answer. The third question will take time for students to understand but will help them to read a graph and to see the types of information they can get from a graph. After students graph their data, have the students answer the following questions about their experiment for their conclusions.

    They will be instructed to:

    • Use only the data they collected to answer the following questions.

    • Don't use any previous opinions, don't make up information and don't use other students' data to help answer these questions.

     

    QUESTIONS:
    1. Did your data support your hypothesis or not?

    2. Summarize your results.

    3. Why do you think your results came out the way they did?

    4. If you had to do the experiment again, what would you do differently so that you could more accurately answer the question in your problem statement or test your hypotheses?
