Video Notes We will watch Part C of a series on the Galapagos islands Watch the clip, and write down EIGHT FACTS that you learn about the islands 4&
Let s share out Video Notes 5&
Do-Now Read the introduction! Look at the table of mice:! It shows the color, age, offspring, and speed of 4 different mice! Use the information to answer the questions on the front page! Remember: % = part/total x 100 Part B Count out 25 of each type of bean.! In your group, choose three members to be PREDATORS.! Pick one person to be the TIMER.! If you have an extra person, make them the REFEREE. 6&
Part B Each predator needs to take a different utensil: one will have a fork one will have a spoon one will have a knife chopsticks Part B During a timed period, the predators will try to capture ONE prey at a time! NO MASS CAPTURE - ONLY ONE AT A TIME! one hand holds the utensil and the other holds your bag/cup! You will place the prey in your capture bag or cup before capturing another! You must stop when time is up 7&
Part B After time is up, count and record (in the table) how many prey of each type is captured by each predator Trial One For the bottom box, fix the totals to account for the fact that we started with only 25 of each type, and no peas. 8&
Trial One Mix beans up across your area! Have predators ready! Make sure one hand is holding the bag/cup and one hand is holding the utensil AT ALL TIMES! Remember: you may only pick up ONE prey at a time! You will have 1 minute 1 minute 9&
Trial One Count and record how many of EACH TYPE of prey each predator captured Write the numbers in the data table Trial One Now, count up how many of each type of prey survived Then, add double the number for each type of surviving prey For example, if I have 10 white beans left, then I want to add 10 more Write the number of each prey you re starting with in Table 4 When finished, mix up all of your prey so they are randomized. 10&
Trial Two The least successful predator is now EXTINCT :( You will help referee now. Make sure one hand is holding the bag/cup and one hand is holding the utensil AT ALL TIMES Remember: you may only pick up ONE prey at a time You will have 1 minute Trial Two: One Minute 11&
Trial Two Count and record how many of EACH TYPE of prey each predator captured! Write the numbers in the data table Trial Two Now,&count&up&how&many&of&each&type&of&prey& survived& Then,&add&double&the&number&for&each&type&of& surviving&prey& For&example,&if&I&have&10&white&beans&leW,&then&I& want&to&add&10&more& Write&the&number&of&each&prey&you re&star`ng&with& in&table&4& When&finished,&mix&up&all&of&your&prey&so&they&are& randomized.& 12&
Trial Three The least successful predator is now EXTINCT :( You will help referee now. Make sure one hand is holding the bag/ cup and one hand is holding the utensil AT ALL TIMES Remember: you may only pick up ONE prey at a time You will have 1 minute Trial Three: One Minute 13&
Trial Three Count and record how many of EACH TYPE of prey each predator captured! Write the numbers in the data table! Write&the&number&of&each&prey&you&would&be& star`ng&with&in&genera`on&4&table&4& Post-Lab Double-check your totals with your group members Answer the post-lab questions on a separate piece of paper When finished, staple questions to the back of the lab Finally, work on your binder assignments 14&

Power Notes 10.4 Key Concept: Evidence of common ancestry among species comes from many sources Evidence of Evolution Main Idea: Evidence of common ancestry among species comes from many sources Four main sources of evidence for evolution: Fossils Geography Embryology Anatomy 19&
Fossils What are fossils? http://www.brainpop.com/science/ diversityoflife/fossils/ 20&
Fossils Transitional fossils show the change from one species to the next! Fossils show descent with modification! Fossils in older layers are more primitive + in upper layers are newer 21&
22&
Geography Island species resemble mainland species! Variation on different islands shows that the main species evolved into separate species 23&
Embryology Embryos = the first stage of development (pre-babies)! Embryos of vertebrates such as fish, birds, reptiles, and mammals look very similar! Embryos with similar features show that organisms may have shared a distant common ancestor Anatomy Two ways anatomy provides evidence for evolution: Homologous structures Vestigial structures 24&
Anatomy Homologous structures:! Features in different organisms that are similar in structure but have different functions! Imply a common (shared) ancestor Anatomy Vestigial structures! Remnants of organs or structures that no longer have a function! Implies that an ancestor used the structure 25&
NOT evidence Analogous structures:! Structures that have a similar function, but developed SEPARATELY! NOT evidence of a common ancestor!! Formed due to similar environments or selection pressures Examples Butterfly vs Bird wings Ant legs vs human legs Whale fins vs fish fins 26&
