Enzyme Lab Day 2 - Assign IV's and read procedures

Assembly Schedule today for Forecasting Fair

(17th is the last 'B' day tutorial before end of semester!)

Great to see you! (unplanned absence on Tuesday)

Check on last class period's tasks...

If you didn't yet complete Unit 2 Vocab or the Enzyme notes from 1/7 - do it ASAP! You'll be lost moving forward if you don't. Seriously.

Read through Unit 2 Task 2: Enzyme Lab (in Classroom) 
Attached to this task are Slides to use for doing the lab and 
'Enzyme Inquiry Lab Template' as the lab write-up after doing the lab.

Assign Independent Variables to groups:
pH, temperature, substrate concentration, enzyme concentration 

Read over procedures carefully together with your group! This is a fairly complicated lab - you must follow directions exactly.

This will help you be more prepared to conduct the lab next class

Recap of project progress; Enzyme Lab Day 1 (Introduction & Notes)

😃Welcome back from break! ❆
Share a rose & thorn with your table while you get settled in..
Unplanned absence - family illness. Sub: Mr. Starke!

WARM UP/Revive your winter break brain:
What are the four types of biomolecules? 

(ask for hands and write on board - check notes for answers)

1.First, check for completion of Unit 2 Vocabulary (show electronic or hard copy for a checkmark)

2.Next, check in on progress... (read below aloud to class)

The Unit Essential Question we're working on is:

Why are captive elephant reproduction rates lower than wild elephant reproduction rates?

What we've done so far:

-Demonstration on the types of biomolecules present in different types of food

-Biomolecules compare/contrast of structure and function

-Research on rhino diets and the role diet plays in the differences in wild/captive reproduction

-Background research on the standards of care for elephants in captivity and AZA diet standards (hand back notes/KWL from 12/20)

In all of this research you should be asking yourself:
Can we apply this to our elephant issue? How?

Check our project progress with these slides and get student group input on the following questions (ask out loud; answer with lab groups):

Do wild elephants' diets differ from captive elephants? How?

Does that impact reproduction? How do you know?


3. Begin Enzyme Lab - Day 1 (3 days total)

Take notes on the information below!

Essential Question: What is an enzyme, and how do they function to break down substrates?

enzyme - a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction

Enzymes are proteins that help speed up reactions in cells. The way they work is similar to how other cell signaling and molecular interactions work: there is a chemical pairing that leads to different outcomes depending on structure. 

They are essential for respiration, digestion, muscle and nerve function, and thousands of other functions. 

Some examples of enzyme functions in humans:

The digestive system - enzymes help the body break down larger complex molecules into smaller molecules, such as glucose, so that the body can use them as fuel.

DNA replication - each cell in your body contains DNA. Each time a cell divides, that DNA needs to be copied. Enzymes help in this process by unwinding the DNA coils and copying the information.

Liver enzymes - the liver breaks down toxins in the body. To do this, it uses a range of enzymes.

Watch Video: Amoeba Sisters - Enzymes (5:46 mins) and take notes

Enzyme Slides HERE (get a chromebook & watch w/group, take notes)

Be ready to discuss next class:
So what's the connection to our elephant project?
HINT...Phytoestrogen (mentioned in Rhino Diet articles) is a hormone signal protein and binds to receptors much in the way that an enzyme binds a catalyst.

If extra time, work on any missing work!

Continue Unit 2 Task 1 work; background research on elephants in captivity

Happy Friday before Winter Break! Almost there...😄
Share a rose & thorn from this week with your table!

Today is the shortest day of the year! Tomorrow is the Winter Solstice video, Nat Geo video

All work from Unit 1 (Tasks 1-8) are due today! Please come to tutorial at 2:30 today for help if needed.

So far in Unit 2 (Biomolecules) you should have completed the following:
-Compare/contrast biomolecules activity (Task 1)
-Guided Reading CER on Rhino Diets (Task 1)
-Group Contract with roles (hard copy turned in to me)
-Vocabulary terms (due on 1/7)

Last class you decided on roles within your groups that you will assume throughout our Elephant Project

(Ms. Ferro's role is Institute for Conservation Research Principal Investigator in Reproductive Endocrinology)

We can keep track of the questions we're answering with each activity/lab by following the Elephant Project Progress Tracking document

TO DO today with your table group:

1) Read the following information for background research on elephant reproduction in captivity:
-Smithsonian Article: Great Expectations
-AZA (Association of Zoos & Aquariums) has standards of care and management for animals in captivity. HERE are the AZA standards for elephants - read through it and look specifically for information about diet, taking notes.

2) With your table group, create a hypothesis about what role diet might play in the difference in reproduction that we observe between wild and captive elephants

3) Create a KWL chart of your understanding of the issue thus far. What did you already know, what do you want to know, and what have you ultimately learned about elephant reproduction in captivity?

Turn in your notes, hypothesis, and KWL chart when finished.

If extra time, work on other Biology work!

End class with a 5 minute Elephant 101 video

Have a wonderful Winter Break! ❆⛄🙌🎄😴🍪

-Synergy has been updated and is current
-Hard deadline for all fall work is the last day of class before winter break: December 20th

OK...science!

Essential Questions we've asked this year in biology:
How has the land in Portland Metro area changed over time?
How do certain factors affect arthropod biodiversity at Tabor?
How can we conserve urban biodiversity as the Portland Metro Area’s human population continues to grow?

In biology textbooks, ecosystems and biomes are generally described in 'ideal' terms, without including humans as a participant in ecosystem function and processes. As we have learned throughout our studies this fall, humans in Portland and around the world are influencing ecosystem function and stability. (I'm looking at you, climate change.)

As the final assessment for our ecosystem unit, you will complete an 'Ecosystem Stability & Change' project.Through this project, each person (or pair of people) will be responsible for exploring and explaining the specific ways in which humans are impacting particular global ecosystems, moving them away from the textbook model. (we will spend the next 4 class periods on this)

In Google Classroom:
First, browse through the list of articles that highlight ecological issues caused by humans in different areas of the world. Claim a topic by signing up on the document shared with your class period (work independently or in pairs).
Then, complete the article summary document.

You will also analyze the trophic levels and food webs associated with your ecosystem (Wednesday) and present a brief description of your ecosystem/issue (Friday).
The final unit assessment will be on Tuesday, Dec. 10th
