Grade Level: 7

Unit Topic/Theme: Evolution

Part One:

Know:

 fossil fossil record extinct homologous

 structure vestigial structure

Understand:

 fossil evolution adaptation descent with

 modification natural selection

 population variation artificial selection gene pool microevolution gene flow

Do:

 Students will understand that that evolution of plants and animals takes place over thousands of years.

 Students will understand that natural selection provides animals with certain characteristics a better chance at survival as compared to their non – gifted counterparts.

 Students will understand that the fossil record contains detailed information about life on earth.

 Students will understand that both genetic variation and the environment are factors that cause evolution and the diversity of organisms over time.

Students will be able to:

 Describe information the fossil record contains about life on Earth.

 Explain how similarities in structure and development among different species are evidence for evolution.

 Summarize Darwin's theory of natural selection.

 Compare and contrast artificial selection with natural selection

 Describe the two main points of Darwin's theory.

Part Two:

Day One:

For the first day, I want to get the kids interested in the topic of evolution. To do that, I plan to use a couple of my animals (possibly class pets) and use them in my opening in order to get their attention. I will then ask the students what they think they already know about evolution. I plan to bring in my crested geckos along with a snake and a taxidermy crow and use them to explain the common ancestor theory and vestigial structures as well as adaptations that certain animals have over others. After I get the kids interested, I plan to continue my power point and continue to bring in the animals when possible to help keep their attention (as well as possibly show them that reptiles are not the scariest thing in the world). For these power points, I plan to use a lot of pictures in order to help kids like

Sarah who have a reading disability as well as Ian who may not understand my entire lecture. I also plan to hand out the worksheet that will be due the day of the Lab (wed).

Day Two:

Probably the most boring day out of this lesson, I plan on using the majority of the day continuing the power point. During the middle of the power point or when the kid’s eyes start to glaze over I will stop and do the natural selection simulation with the kids. I will assign a think tac toe board to students who want to get ahead or need more of a challenge

(my two gifted learners). I will explain to the kids since it may be their first time how a think tac toe board operates and explain the rule and expectations (especially in private to my gifted kids… I expect you to at least to …) Finally, I plan to do thumbs up assessment to see where the students believe they are at.

Day Three:

For this day, I plan to walk in wearing my lab coat (a signal to my students that today is a lab day). I plan to start off class by collecting the worksheets that were due. I will then do a quick lesson over the peppered moth theory to give the kids an overview of what this lab is about. I then plan to separate up the kids into pairs of 2 –keeping Scott and Emma in the same working groups and do a higher leveled tiered assignment, along with the 5

“strugglers” all into different groups so they the groups are relatively evened out. I also plan to put Sarah and Ian in the same group so that I can assign them a different tiered lab so that they can still learn the material and so that I can help them when necessary. I will also pair up the remainder of the students so that they can no feel like this was chosen in a particular order. I will explain the instructions to the main class and allow them to start

working and then I will confront Ian and Sarah and give them their instructions along with

Scott and Emma. Throughout the class period I will be walking around assisting the students if needed. Before I end the time for the lab I will make sure all of the students have what they need so that they can finish the remaining questions for homework. At the end of the class- remaining 15 min or so- I will give them clean up instructions along with a short quiz – tiered to each of the student’s needs. I also plan before they are allowed to leave to do a quick thumbs up or down assessment to see where the kids are at with the topic.

Day Four:

After, an in class grading of the quiz from the day before, I plan to use as much time as needed to cover any topics or questions that the students have about the quiz or last few days. The remainder of the period will be used as a day to work on the think tac toe boards with me walking around to assist when necessary and answering any questions.

Part Three: Long Form Lesson Plan

Student Teacher: Nicole Perry

6/2/14

State Standard: California State Standards

Grade Level: 7 Date:

3. Biological evolution accounts for the diversity of species developed through gradual processes over many generations. As a basis for understanding this concept: a. Students know both genetic variation and environmental factors are causes of evolution and diversity of organisms. b. Students know the reasoning used by Charles Darwin in reaching his conclusion that natural selection is the mechanism of evolution. s when the environment changes and the adaptive characteristics of a species are insufficient for its survival.

Peppered Moth Simulation

Objectives:

Describe the importance of coloration in avoiding predation

Relate environmental change to changes in organisms

Explain how natural selection causes populations to change

Materials

Sheet of white paper and newspaper

Forceps

Clock with Second Hand

30 newspaper circles 30 white circles (made with hole punch)

Purpose

In this lab, you will simulate how predators locate prey in different environments. You will analyze how color affects and organism's ability to survive in certain environments.

Industrial Melanism is a term used to describe the adaptation of a population in response to pollution. One example of rapid industrial melanism occurred in populations of peppered moths in the area of Manchester, England from 1845 to 1890. Before the industrial revolution, the trunks of the trees in the forest around Manchester were light grayish-green due to the presence of lichens. Most of the peppered moths in the area were light colored with dark spots. As the industrial revolution progressed, the treee trunks became covered with soot and turned dark. Over a period of 45 years, the dark variety of the peppered moth became more common.

Procedure.

1.

Place a sheet of white paper on the table and have one person spread 30 white circles and 30 newspaper circles over the surface while the other person isn't looking.

2. The "predator" will then use forceps to pick up as many of the circles as he can in

15 seconds.

3. The number that are left are doubled to represent the next generation

4. This trial will be repeated with white circles on a newspaper background,

newspaper circles on a white background, and newspaper circles on a newspaper background. Record the data in chart below.

Part Five: Copy/Paste/Create two forms of assessment below.

Assessment #1 Informal thumbs up assessment

I use this couple of times throughout the week’s lessons. This particular method will allow me to be able to get a general understand of how my students are feeling throughout the week without making the kids groan about taking “another quiz”. After the second time I ask them if there is still a large number of students who still do not understand the material that is a huge indicator to me that I need to cover the material over again instead of just continuing on.

Assessment #2 Formal assessment: Labs

Labs are collected and analyzed in order to see if the students understand the material. It will also show the participation when they turn in the work (if both members have the same exact answers “red flag”) as well as me watching them in order to make sure it is not just one person.

I also have other forms of assessment listed throughout the week; those include think tac toe and a quiz.
