Warm-Up: copy this data table onto the BOTTOM HALF of p 31 Unique things about glider Things glider has in common with all others Date Session # Activity Page # 1/9,12 Sorting Finches 29 1/13-14 Principles of Evolution Stations Review 30 Evidence of Evolution 31 Evidence of Evolution Notes 32 h/w: Read pages in 28B-34B textbook Answer questions 5-15 on page 37B

8.L.4 Understand the evolution of organisms and landforms based on evidence, theories and processes that impact the earth over time. 8.L.4.1 Summarize the use of evidence drawn from geology, fossils, and comparative anatomy to form the basis for biological classification systems and the theory of evolution

TLW analyze evolutionary relationship between organisms by comparing and contrasting structures, reviewing notes and answering analysis questions.

Review Stations p.30 You will silently move through the stations. You may use your notes. For each station Identify what principle of evolution is being illustrated Explain your reasoning There are 6 stations

Fly Away You will have 3 minutes to design and construct a paper airplane glider of that will stay in the air for 5 seconds and travel at least 20 feet. BE CREATIVE: the challenge is to create designs that are as different as possible but still meet the criteria.

Compare & Contrast Structures Similarities Differences

Contents, Covers and the stories they tell Part 1 Carefully examine the bone structures on Lab Sheet 1. (Note: bones are not drawn to scale.) All are forelimbs of mammals. Look for key structural features that give tell-tale clues about which mammal the bones are from. Bone Set Key Structural Features Proposed Animal Source A B C D Five separate digits or fingers; hand-like structure; long, thin upper and lower arm segments Human E

Contents, Covers and the Stories They Tell Part 2 complete this on page 31 Examine the skin- and/or fur-covered limbs on Lab Sheet 2. On page 31, describe the relationship between each limb structure and its normal function. Example 1 mole The mole’s forelimb is a structure with short, strong levers and sharp claws for digging. (since is lives underground) Continue with the other mammals and similarly describe the relationship between the structure and function of their forelimb.
