  • Survival of the Fittest Lab

    Objective: To simulate the process of natural selection using various backgrounds anddifferent colored beans.

    Materials:20 black beans20 white beans20 kidney beansBlack construction paperGreen construction paperWhite construction paper

    Procedure:1. Place all of the beans onto the white construction paper.2. Both students in the group will close their eyes for 15 seconds. After 15 seconds,

    open your eyes and pick up the first bean that you see and place it aside. Closeyour eyes and count to 10. Open them and grab the first bean you see. Do this 10times.

    3. When you are done, count the beans remaining on the white paper. Record theinformation in your data table. Then count the beans that you picked off of theconstruction paper. Fill in the numbers in the data chart provided.

    4. Now place the beans onto the black construction paper. Repeat steps 2 and 3.5. Place the beans onto the green construction paper. Repeat steps 2 and 3.6. Clean up your work area and answer the questions below.7. Make a comparative bar graph to show how your results differed for each trial.

    Answer the following questions:1. On the white construction paper, which bean survived the best? Why did this

    bean survive the best?2. On the green background, which bean survived the best? Why do you think

    this bean was a survivor?3. On the green background, which bean survived the worst? Why didnt this

    bean survive?4. What would eventually happen to the population of the beans that did not

    survive? Why?5. On the black background, which bean survived the best? Was it the same or

    different than the bean that survived on the green background? Why do you thinkthis is so? Explain.

    6. How does this lab simulate the process of natural selection?
