5 & 9 & 11 & 15 May Science 7 Reading article and watching video about Galapagos finch evolution

This is a very interesting video–let me know if you like the technique: https://www.youtube.com/watch?v=R9irpz6ZZk8

Hint: Refer to the last paragraph of Origin of Species that we read at the beginning of the semester. You wrote a blog post about your thoughts.

5 May Reading and Video–context for Assessment

You will receive a paper packet. Be sure your name is written on it. DO NOT TAKE IT FROM THE CLASS. Turn in the packet at the end of class. You will use this on 9 and 11 May. The summative product is due at the beginning of class on 15 May (paper AND digital copy). There can be no late submissions as we are at the end of the semester. Plan now to turn your work in on time!

finches  (Read pp. 121-124. Read about activity pp. 125-134–do not conduct this activity–just prepare your mind. Read about activity pp. 135-140–do not conduct this activity–just prepare your mind. Read about activity pp. 142-144–do not conduct this activity–just prepare your mind. )

We will watch this video together on 5 May. Take notes and be sure to ask questions.



9 May Conducting experiment

Carry out the bird beak simulation (see handout or link above). Additional instructions will be given in class. Collect all data.

As individuals:

Make a visual display of the data (be sure to following good graphing practices–choose a scale that covers all the data, that makes the graph as large as possible AND that is convenient). Label axes with variable name and unit. Include a title. Graph first in pencil and make sure it is correct before using ink. Write a summary of the simulation explaining the procedure, the data, and the way natural selection of beak size is modeled. Be sure to connect the data to your ideas. Also describe which parts of the simulation correspond to reality and which parts do not. Also make a statement referring specifically to the standards. The visual display and written portion are due at the beginning of class on 15 May. They should be submitted in hard copy AND uploaded correctly in your digital science notebook. You must do original work.

Natural Selection and Adaptation SA

  1. Students will carry out a simulation related to the natural selection of bird populations in the Galapagos. The simulation will generate quantitative data based on bird beak size.
  2. Data is collected from the bird beak simulation and analyzed.
  3. Analysis is made and conclusions drawn with respect to structures, environmental effect on bird populations, adaptations, and natural selection.
  4. Product: 1. Visual presentation of the collected quantitative data and analysis. 2. A brief summary of the simulation, collected data, and the cause and effect relationship between beak size and natural selection of bird populations.

The learning standards to be assessed:

Science and Engineering Practices

  • Developing and using models
  • Using mathematics and computational thinking

Cross Cutting Concepts

  • Cause and effect
  • Structure and function

Disciplinary Core Ideas

  • Natural selection and adaptations
