Tentative Weekly Agenda and Homework 10/21 - 10/25


IN38 Activity 10: Energy and Matter in Food Analysis Questions Due Tuesday 

Complete 1-2 in your Notebook IN38 

  1. 1. Why do living organisms need
  2. a. food?
  3. b. energy?
  4. c. matter?
  2. 2. Describe what happens to matter, such as a protein or a carbohydrate, after it is eaten. Be sure to include 
  • each step as the body uses the protein or the carbohydrate.
  • where each step occurs.

Complete 3-4 on  a separate page to be collected 

  1. 3. Based on what you have learned in the “Cellular Respiration” activity and this activity, draw a diagram (or create another type of model) to show what happens to the food an animal eats. Your model should show the movement of matter and the release of energy stored in food. You can copy the partial diagram from the textbook onto a sheet of paper to get you started. 

4.  Use your answer from Analysis item 3 to explain how matter is neither created nor destroyed in the processes shown in your model.  


Tentative Agenda/HW for 10/14 - 10/18


(Separate Sheet of paper to turn in) Due THURSDAY, will be graded  

Analysis Question #4 A54 

Prepare a written analysis of your data. Your analysis should include 

  1. a statement of the problem you were trying toresolve.
  2. an analysis of the results, which should include
  • a copy of both datatables.
  • a summary of the results shown by the data in your data table.
  • answers to thesequestions:

––What was the purpose of Cup 2? 

––What differences did you observe between yeast in the presence of glucose and starch?


3. a conclusion that

  • responds to the question, What evidence do you have that yeast cells are alive?
  • describes any problems you may have had with the investigation.
  • describes any additional questions related to the problem that you would like to investigate.


Tentative Schedule and HW for 10/7 - 10/11


TENTATIVE Weekly Agenda and Homework 9/30 - 10/4


(IN30) Finish Analysis Questions A-40 


1. What did you learn about the diet of owls from investigating an owl pellet? Include information about the type and number of organisms in an owl’s diet. (Remember that an owl ejects a pellet within 12 to 24 hours after eating.) 
2. Begin constructing an owl’s food web. You will return to this food web in later activities. 
  1. a. The organisms that you uncovered in your owl pellet are likely to be voles—small rodents similar to mice. Owls also eat other small mammals, such as shrews, and insects. Use this information about an owl’s diet to develop a food web. 
  1. b. Voles eat mostly plant material, such as grass, seeds, roots, and bark. Shrews eat insects. Add these relationships to your food web. 
  1. c. Another kind of owl, the great horned owl, sometimes eats other owls. It also eats small mammals like voles. Add the great horned owl to your food web, and explain how it impacts the rest of the food web. 
  3. 3. Consider your food web when responding to the following items: 
  1. a. What would happen to the food web if a disease caused the populations of voles and shrews to die off? Explain your reasoning. 
  2. b. How would this die-off affect the flow of energy in the ecosystem? 
  1. 4. All living things have a place in a food web. What would your personal food web look like? 


Tentative Weekly Agenda and Homework 9/23 - 9/27


(IN28) Finish Analysis Questions for Homework (A-33 - A-35 or pg  53-55 online)

Answer Analysis questions #1 - #6

See attachment for Number 6, part b


(IN26) Answer Analysis Questions from page A-26 

1. Based on your investigation, which type(s) of material provide a good habitat for blackworms? Explain how your results support your claim.  
2. Based on what you now know about blackworms, in what type of environment do you think blackworms live? Explain your reasoning. 
3. Adaptive features can include behaviors as well as other characteristics. What blackworm behaviors did you observe that might help it survive in its habitat?
4. What do you predict will happen if blackworms were introduced into a different ecosystem?  
5. As you read in Activity 1, “The Miracle Fish?” the government introduced Nile perch into Lake Victoria in the 1950s, but their population didn’t start increasing until the 1970s. Based on what  

you learned in Activity 5, suggest a reason for this observation. 

Hint: Think about the ecosystem and how it may have changed 


Tentative Weekly Agenda/Homework for 9/16 - 9/20


(A-24) Finish Analysis Questions #1-5 (IN24) 

  1. What was the most common biotic component in your group’s transect? 
  1. What other biotic and abiotic components did you note? 
  1. Describe the relationships you see between the most common type of organism and other components of the environment? 
  1. What questions would you like to ask about the environment? 
  1. How would you test the above questions? 


(IN22) Answer Analysis Questions #1-4 (A-19 or pg 38 online) 

  1. 1. How did the samples vary across the groups in your class? Why do you think this is?  
  1. 2. How did the average number of native plants, non-native plants, and grasshoppers differ in the two prairie locations? 
  2. 3. a. When you compared the two prairie transects, what patterns did you detect? 
  1.      b. What factors or relationships might be the cause of these patterns?
  1. 4. Based on the data, does the current process for restoring the prairie seem to be working? Explain your reasoning.  


Finish creating your procedures and data table for Taking Look Outside (A-22-A-23 or pg 41-42 online) 

  1. Record your procedures for your investigation on IN25. Must be approved by Ms. Colgan before you can collect
  1. Create a group data table in which to record patterns you find in your quadrat. Your table should contain rows for each quadrat sampling point and columns for each component you will investigate.
