Peppered Moth Natural Selection Simulation Lab Purpose predators loca.pdf
- 1. Peppered Moth Natural Selection Simulation Lab Purpose predators locate prey in different environments. In addition, In this lab, you will simulate how you will analyze how color affects an organism's ability to survive in certain environments. Materials Sheet of white paper Newspaper Forceps (tweezers) Colored Pencils Stopwatch or Clock with Second Hand 30 newspaper circles (made with hole punch) 30 white circles (made with hole punch) Procedure 1. click on the following link to learn more about the Peppered Moth. https len wikipedia moth evolution circles 2. Place a sheet of white paper on the table and have one person spread 30 white and 30 newspaper circles over the surface while the other person isn't ooking. 3. The "predator will then use forceps to pick up as many of the circles as he can in 15 seconds and then record the data. 4. Repeat steps 2-3. person spread 30 white circles 5. Place a sheet of newspaper on the table and have one and 30 newspaper circles over the surface while the other person isn't looking. 6. The "predator" will then use forceps to pick up as many of the circles as he can in 15 seconds and then record the data. 7. Repeat steps 5-6. Lab Report: following After completing this lab you will create and turn in a formal lab report with the elements -observation (20 pts.) An introductory section that is written in paragraph form. Please include the following elements within your writing What is the purpose of this lab? Background research on peppered moths explaining their habitat and how and why their population has shifted. Hypothesis: Written as a statement. (What do you think will happen in your experiment after reading the purpose and the procedure?) Solution Peppered moths are two types; one has white and other has dark color. The color of white paper and newspaper is also different and they represent colors of moths and color of their liking perspective environment. White color of the paper should make attraction of predator for newspaper circles but not for white circles. It is because white circles in white background will less observable but the newspaper color (which is dull) is clearly visible in the white background. There’s the moth use to hide and predator use to capture. The phenomenon under newspaper background will show the inverse behavior from the white background condition (described above The purpose of this lab is to observe predator response according the color of the environment for two definite preys. The population of moths increases in their similar color environment. The dark colored moths like dark environment and white colored moths like white environment. Dark colored moths were not observable until year 1811 because of less pollution. The white colored moths are
- 2. always has hiding capacity in clean environment but they have to adopt by the falling of clean environment. This shows the evolution of moths according the environment. Hypothesis: If predator fails to select white and dark color circles more in their same color environment then the preys are using like color like environment phenomenon for their protection.
