The Mandella Environment

Enter subhead content here

Monday: A Day

Aim: Beaks of Finches: Adaptation, hinder or help?

Do Now: Lab folders: Record Lab #22. Beaks of Finches

Procedure: Students will simulate natural selection by using different tools to see which are best adapted for the task of picking up seeds and transporting them from one container to another. They will use different tools (representing beak variation in finch species) to pick up seeds, which represent food on different islands. Follow procedure of lab. This is a state required lab. Students must complete Lab skill packet and the final lab report.

Homework #21: Chapter 27 in UPCO Book Page 465 Part A, C, D, and E all questions.

Tuesday: B Day

Aim: How do sceintists explain the variety of living things on earth?

Do Now: Using the overhead display a picture with lizards in various environments. Ask students what they think will happen the lizards in each picture. Procedure: The do now will bring about a discussion focused on camouflage. Have students discuss what camouflage can do for an organism. Define adaptation and ask students if the term fits the idea of adaptation.

Homework #22: Chapter 27 in UPCO Book Page 465 Part A, C, D, and E all questions.

Wednesday: A Day

Aim: What adaptation aided or hindered a finch?

Do Now: Lab teams will get together to continue working on their lab #22. Lab folders: Record Lab #22. Beaks of Finches

Procedure: Students will complete their lab reports.

Homework #23: Regents Review books. Reread pages 73 and 74 Answer questions 6-12.

Thursday: B Day

Aim: What is a source for new traits that help living things survive? How can new species appear on earth?

Do Now: What are your traits controlled by? Is this the same for all animals?

Procedure: Today we will discuss both mutations and species formation. Mutations are natural events that appear in every living thing. These changes in genes may be helpful, harmful or have no effect at all on a species.  We know that mutations come from a change in the DNA code.  Gene mutations can cause the appearance of an animal to change and cause harm to an animal. Page 609. What will the color of this deer do? Have studnets look at several mutations in animals and write how the mutation can be harmful or helpful to that organism.  Species formation. Define species ( a group of living things that can breed with others of the same species to form fertile (able to reproduce) offspring.  Use the overhead transparency to show students a scenario of rabbits being separated. Ask them to explain how species A could turn into both  species C and D. Did the environment play a role in their changes? How? Now explain how the finch species evolved into many different species on the Galapagos Islands. Why would their beak formation evolve?

Homework #23: Complete the study guide worksheet. Questions 6-10 all parts.

Friday: A Day

Aim: Who is Charles Darwin?

Do Now: Look at Page 613 of the Glencoe text.  Do humans evolve from primates or is it believed that we evolves from similar ancestors?

Procedure: Spend some time to give a brief history of the origin of living things according to LeMarck's theory. (Display photos of animals blending in with their surroundings.) How do traits help an organism survive in its environment?  Natural selection. How does it work? Charles Darwin Englishman 1850's. traveled around the world and collected data to support his theory of natural selection. Nature acts as a selecting agent of an organisms traits. Organisms better adapted survive and reproduce more successfully. Also Alfred Wallace) Copy Darwins theory from UPCO books and distribute to student's for notes. Discuss each step of his theory. 


Have a great weekend!
