How do we smell?

Watch TedEd video “How do we smell?”

In your journal, write a hypothesis for the question: How do our olfactory receptors distinguish between different smells?
Read “The Role of the Active Site” and revise your hypothesis.

Model Olfactory Receptors
1. Work in pairs to create a model of olfactory receptors that meet the shape and chemical property requirements of the provided “smell molecules” (puzzle pieces).
2. Using your model, create a stop motion video to explain how the olfactory receptors work using the terms: functional groups, receptor, active site, chemical properties (of amino acid R-group).

Protein Folding

Goal:

Model how the intermolecular forces between amino acids cause proteins to fold in predictable shapes. Hypothesize how the structure of the folded protein might contribute to its function.

Agenda:
Warmup
ACT Reading
Protein Folding Activity
Revised CER

Warmup
Create a new journal entry entitled "Protein Folding."
Copy down WHAT we are learning today.
Write a CER to answer the question: What structural features of a polypeptide most contribute to protein folding? Explain.

ACT Reading
Read and answer the questions to this ACT practice passage.

Protein Folding Activity
Follow the directions in this document to complete the protein folding activity. Then answer the following questions in your science journal:

1. Take a picture of your folded protein and explain how you arrived at this shape.  Use the words secondary and tertiary and include a discussion of R-group properties (such as charge etc.)
2. What step needs to occur next before the protein can be considered “complete”?
3. Imagine for a moment your protein has a “job.”  Be creative and explain how it’s shape might help it do it’s job.  Refer back to the 9 types of proteins  for ideas.

Revised CER
Use what you learned in the protein folding activity and the ACT reading to revise your CER from the beginning of class.

Protein Structure Basics

Goal:
Identify the characteristic structural features of proteins at the primary, secondary, tertiary, and quaternary level.

Video Notes Worksheet - Open in Notability

Warmup
Create a new journal entry entitled "Protein Structure Basics."
Copy down WHAT we are learning today.
Write a CER to answer the question: Considering what you learned in the last two lessons, do you think all proteins have similar or different structures? Explain.

Video Notes
Use this Bozeman Science video  to complete the Video Notes Worksheet.

Similarities/Differences
Work on whiteboards in table groups to outline the ways that all protein structures are the same and how their structures are different. Then use this information to revise the CER you wrote at the beginning of class.

Socrative
Login and take the quiz.

Types of Proteins

Goal:
Describe the 9 different functions of proteins in the human body.

Agenda:
Warmup
Protein Slides
Protein Game

Warmup
Create a new journal entry entitled "Types of Proteins."
Copy down WHAT we are learning today. Hint: It's written on the whiteboard and at the top of this blog post.
Write down everything you know about proteins.

Protein Slides
In your groups create a google slides presentation entitled "Types of Proteins." Share it with your table-mates and me.
​Use this website as a starting point. Create 1 slide for each type of protein that includes:

1. ​Name of Class of Protein
2. Role of that type of protein in the body
3. Example of what your specific protein does
4. Visual representation to help you remember

Protein Game

Work with your elbow partner to complete the protein scavenger hunt. Winner gets stickers! Finishers get stamps!
