6. A few weekends ago, the 7th grade science teachers went to Citifield to catch the Mets game. They arrived early and grilled up some yummy chicken wings to enjoy before the game. As you know, chicken is made of Protein. Let’s create a model of the chicken protein together now

7. Lego Protein Model Challenge
Step 1: Eating Protein
Create a model of the chicken muscle using the small amino acid code segment ARG – CYS – GLY – GLN – ILE – VAL
HOLD UP YOUR MODEL WHEN YOU ARE FINISHED

8. Lego Protein Model Challenge
Step 2: Digestion
Since you aren’t a chicken, you can’t use this protein molecule as it is when you ingest it. Water and enzyme action allow you to digest it; in other words, break it down into small amino acids.
HOLD UP YOUR AMINO ACIDS WHEN YOU ARE FINISHED DIGESTING THEM.

9. Lego Protein Model Challenge
Step 3: Assembling YOUR Protein
You need to replace red blood cells, which contain oxygen grabbing protein called hemoglobin. Create a model of hemoglobin using your amino acid blocks.
CYS – ILE – GLN – ARG – GLY – VAL - LYS
HOLD UP YOUR PROTEIN WHEN YOU HAVE FINISHED.

10. Data Table 1: Positive vs Negative for Protein Procedure A: Testing Known Substances
