Monday:
1. took notes over natural selection and speciation
2. wrote scenario over speciation
Homework: Work on ECA packet - due next week
Learning Goal: Apply what you have learned about natural selection.
Bellwork:
If two populations of the same species of insects have been geographically isolated from each other for an extended period of time, they will MOST LIKELY exhibit a. increased rates of genetic mutation b. very few differences in terms of appearance c. evolution into two different species that can mate and interbreed d. different traits that allow each to better survive in its particular environment
Tuesday:
Students will take notes over Genetic Drift
Homework: ECA Packet
Learning Goal: Students should be able to explain how genetic drift affects populations.
Bellwork:
All of the scenarios are examples of evolution, with the EXCEPTION of the a. loss of hind limbs by whales b. gradual loss of toes on the feet of horses c. change of a caterpillar into an adult butterfly d. change of bones in ostriches, from hollow to solid Wednesday: Students will take notes over disruptive, stabilizing, and directional selection Homework:ECA packet Learning Goal: Students must be able to identify disruptive, stabilizing, and directionsal selection. Bellwork: What is the term given to organisms, such as kudzu or zebra mussels, that when introduced into a new ecosystem, thrive and reproduce quickly often causing native species to become extinct? Thursday: Students will take notes over Hardy-Weinberg Homework: ECA packet Learning Goal: Students should be able to name 5 reasons when the Hardy-Weinberg principle doesn't work. Bellwork: In a field of sunflowers, there are varying heights. A plant that is too short may not be able to compete with other plants for sunlight. However, extremely tall plants may be more susceptible to wind damage. Combined, these two selection pressures select to maintain plants of medium height. The number of plants of medium height will increase while the numbers of short and tall plants will decrease. This is an example of __________ selection. Friday: Students will take a practice quiz over the ECA. We will review this in class. Homework: ECA review packet - due next week (the day of the test)! Learning Goal: Get ready for the ECA Bellwork: none
