Overview
In this unit students will learn that in any particular environment, the growth and survival of organisms and species depend on the physical conditions.




Questions to Ponder
  • What are some ways that you are similar to other people in your family?
  • What are some ways that organisms use their differences to survive?
  • What is some evidence that organisms on our planet have changed over time?
  • What do you think might change about humans in the next 1,000 years to make us better adapted to our environment?





Moths_1.png
Peppered Moth Simulation



Objectives:
  • Describe the importance of coloration in avoiding predation
  • Relate environmental change to changes in organisms
  • Explain how natural selection causes populations to change
PurposeIn this lab, you will simulate how predators locate prey in different environments. You will analyze how color affects an organism's ability to survive in certain environments.
Materials1 sheet of 8 1/2" x 11" white paper1 sheet of 8 1/2" x 11" black paperTweezersClock with Second Hand or stopwatchaprox. 15 black circles (made with hole punch)aprox. 15 white circles (made with hole punch)

Procedures
  1. Read all procedures and copy the data table below.
  2. Place a sheet of black paper on the table and have one person spread all of the circles (white and black) over the surface while the other person isn't looking. The person not looking is the "predator."
  3. The "predator" (eyes open now) will then use tweezers to pick up as many of the circles as they can in 15 seconds. Count how many of each circle you collected. Use the data table to record how many of each type of paper circle the people in your group collect.
  4. Repeat this trial on the same black paper background for everyone in the group and then do the same thing using the white paper background. Record all information on your data table.

Analysis
  1. Go to the following link to answer the questions as a group: Peppered Moth Simulation Questions
  2. Add the the following terms to your notes on Evolution:

    • species
    • traits

Here is a great site that reviews the peppered moth concepts.



Oyster Farming Simulation
In the Peppered Moth Simulation we observed how species can change as a result of changing conditions in their environment. When better adapted organisms out-compete other organisms it is often referred to as Natural Selection. In this next simulation we will look at how humans can have a direct affect on a species and whether they survive or not. This is called Selective Breeding.
  1. Watch the following slideshow about The History of Chesapeake Oysters:
  2. Read the Oyster Disease Article:
  3. Use Bubbl.us to create a graphic organizer about the reading
  4. Now you will learn about how oysters are bred. Download Oyster Farming simulation and complete as a group.
  5. Now, you need to come up with a plan to help the oysters in Chesapeake Bay.Download and complete the Oyster Management Plan.
  6. Add the the following term to your notes on Evolution:
      • selective breeding




World Domination Rabbit.png
Natural Selection Simulation
  1. Use this worksheet to guide your work
  2. Go to this site to explore natural selection by controlling the environment and causing mutations in bunnies.
    • at the Phet site, click on Run Now to begin the simulation.
    • start by adding a friend and changing the variables such as hair color, teeth, etc.
  3. After about 5 minutes of exploring the program, go back to the worksheet and answer the first three questions.
  4. Now, complete some experiments by changing only one variable at a time. Record your observations next to each of the variables on the worksheet.
  5. Answer this question.
  6. Add the the following terms to your notes on Evolution:
    • adaptation
    • variation
    • mutation

Thingdom
Selective Breeding Simulation
In this simulation you will be responsible for a Thing. You must adopt, care for, and make baby things as you learn about the concept of Selective Breeding.

Procedures
  1. Read all procedures.
  2. Go to this link for the form to fill out as you play.
  3. Click here to begin the simulation. Be sure to take time to read everything on each screen and follow the directions.
  4. Finish filling in all of the answers on the form. Be sure to double check your work before you click submit!
  5. Add the following term to your two column notes on evolution:
    • selective breeding

Here is another Selective Breeding simulation.

Iguana_1_1.png
Darwin's Observations


  1. Add the following terms to your notebook:
    • Evolution
    • Natural Selection
  2. Check out this site to learn all about Charles Darwin and his amazing voyages and discoveries.
  3. Check out this site to learn about some of the other science that Charles Darwin worked on.

Summary of Evolution Concepts


Plant Scavenger Hunt
Objectives
Students will:
  • Understand how a plant’s structure can reflect adaptations to its environment
  • Be introduced to the structure and function of leaves and roots
  • Observe and begin to recognize several woodland plants

Purpose
  • Students will search for certain types of plant adaptations.

Materials
  • notebook


Procedures
  1. Watch the following slideshow to learn about the different types of environmental conditions to which plants may need to become adapted:





Notes_1.png

Evolution

Key words
Definitions, facts, examples
Selective Breeding
· Selection for specific traits imposed by humans, either deliberately or otherwise, upon wild or domesticated plants and animals
· Farmers breed animals with most desirable traits
· Ex. Breeding sheep with the finest wool
Traits
· A characteristic that an organism can pass along to its offspring through its genes
· Ex. – stem height or seed color
Species
· A group of similar organisms that can mate with each other and produce offspring
· There are 1.7 million different species of organisms on Earth
Adaptation
· A trait that helps an organism survive and reproduce
· Ex. – talons of a barn owl
Evolution
· The gradual change in species over time
· A theory (a well tested hypothesis) proposed by Charles Darwin
Natural Selection
· Individuals that are better adapted to their environment are more likely to survive and reproduce
o Overproduction – organisms produce more offspring than can survive
o Competition – fighting for resources
o Variation
Variation
· Differences between individuals of the same species
· Can be helpful or harmful to an organism
· Ex. Brown and white fur of a rabbit
Mutation
· A sudden change in an organism’s DNA
· Can be helpful or harmful to organism
