Finals Days (Jan. 22-24); ELISA Lab

Finals Schedule:
Wednesday, January 22nd (Ferro not here)
Periods 1, 2, 4
Thursday, January 23rd
Periods 5, 6, 8
Friday, January 24th
Periods 3, 7

Grading update: all Task 2 CER's that were turned in by 1/22 have been graded and are in Synergy, as well as all revisions that you asked me to re-grade on 1/21

A word of warning: you may not copy and paste lab write-ups from your lab partners. Moving forward, this will affect your grade. Your conclusion and other 'explanatory questions must be in your own words. This is the assessment by which I evaluate your learning.


Today: Begin ELISA Lab 
Here we will learn the background information we need about normal elephant reproduction

Posted in Google Classroom (Unit 2 Task 3)

Students will explore how the San Diego Zoo Institute for Conservation Research has contributed to the recovery effort of the vulnerable African
elephant. Reproductive endocrinology research will be highlighted, with students exploring and utilizing a
mock competitive ELISA as a tool to diagnose reproductive state of our female elephants. After conducting their
investigations, students will analyze, graph, and share their results, culminating with applying their knowledge to
make recommendations for a mock managed care breeding program.

What's "ELISA?" explanation here

All Periods Schedule; Work Time

Period 5 12:06-12:48
Period 6 12:55-1:37
Period 7 1:44-2:26
Period 8 2:33-3:15

What are we doing today? → Structured work time: see below

First, an update on grading:
-All Semester 1 work due by Friday 1/24 at 3:15pm
-You are welcome to keep turning in revisions until then, 
but you must let know either in person or via email if you want your revision grade to show up in Synergy
-I have not yet graded your Task 2 C/E/R

On your finals period we'll be continuing our Elephant Project

Now, please grab a Chromebook & open Synergy and Classroom

1. Did you turn in Task 2: Enzyme Lab C/E/R? 

If yes, move to table 6, 7, or 8 and use your time to work on other classwork.

If no, move to table 1, 2, or 3 and finish it this period! 

2. Did you finish all other biology work? 

If yes, move to table 6, 7, or 8 and use your time to work on other classwork.

If no, move to table 1, 2, or 3 and work on tasks.

Work/Makeup Day on labs



Today is the last B day tutorial before the semester ends!

Please check your biology grade in Synergy and let me know if you have any questions or turned in anything new.

Your Enzyme Lab write up is due TODAY! (Task 2) 
Work with your group and submit it when done.

Let's look at the conclusion question together:

Write a conclusion that answers your research question above. 
(What is the effect of (independent variable) on the activity of catalase as measured by the height of the foam?)

How does this relate to how proteins function in elephant cells?
How are estrogen receptors and estrogen similar to enzymes? You may need to draw upon research from other activities in this unit to connect this. 
Additional info on estrogens HERE


Include a Claim (answer to your question) Evidence (interpretation of information in graph and table) and Reasoning (how this connects to your understanding of cell biology and our Elephant Reproduction investigation).








It's Self Care Week ๐Ÿ’›
How can you better take care of yourself?
Let's go for a walk! ...

Continue Enzyme Lab work (Task 2 C/E/R)

Unit 2 Task 2: Enzyme Lab C/E/R due this Friday
This is your last grade of the semester - can't be late!

You have all period today to work on it with your lab group

Share your data, but you have to do your own writeup

If you need help with the 'Desmos' graphing section of the C/E/R, click HERE 

Work hard & stay focused!

Enzyme Lab Day 3

This week: tutorial Thursday & Friday ❆❆❆
Grades are being updated by Wednesday (per. 5 is done except for Task 8)

Do Enzyme Lab!
(Periods 7 & 8: can I please have 2-3 lab assistant volunteers to help me with glassware, etc. after the lab?)

Safety:
-clear desks of everything except writing utensil
-clear floor of tripping hazards
-pull hair back
-no loose clothing
-food and drinks away
-you must wear protective eyewear and gloves for this lab

You'll need 2 people per group to have a camera accessible

Handouts: procedures sheets, data sheet

Each group needs 2 rulers

Practice using a pipette with a small beaker of water before doing your investigation with solutions!

PLEASE follow directions exactly, the potato catalase solution is difficult to make and we can't waste any to start over

Each of you should take an active role in your group's work
-remember that you signed a group contract. Be accountable!

HAVE FUN! ๐Ÿงช๐Ÿงช๐Ÿงช

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)

๐Ÿ˜ƒWelcome 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!
