Our warm up today was a review of natural selection and adaptation. Next we went over the natural selection homework and completed the notes we started last class on page 53. If you were not here, here are the notes. Next we completed a bird beak lab. Using 4 different types of beaks and 4 different food sources we competed for food. Some of you made adaptations with your beak by flipping it around, some of you died out because you couldn't pick up any food. After completing the lab, we graphed the results and completed the conclusion. If you did not finish the conclusion, here are the questions. 1. According to your results, out of all the beaks, which species has nature selected for? Which species has nature has selected against? 2. According to your results, which “worm” is nature selecting for? What species has nature selected against? 3. If we looked at this population of birds and worms in the next 5 years, how do you think the population will change? 4. How does this activity demonstrate the concept of natural selection? Finally, we completed an activity simulating natural selection using the Peppered Moths and Industrial Revolution. The website for this activity can be found here. Students clicked through the website and answered questions on the Peppered Moths on page 55 in their notebooks. Here is the handout from the Peppered Moth activity. Finish this up for homework, if we don't finish in class.
