1.  Proteins are made of building blocks called amino acids. Use four different color blocks and arrange them in as many different combinations as you can. How many did you get? That’s just a small fraction of the number of possible combinations available when cells make proteins.

2.  Pair up with a friend. When your friend is not looking, write down a sentence with no spaces between the words. Then cut the sentence into chunks six letters long. Trade pieces with your friend and see if each of you can put the other person’s sentence puzzle back together. How is this like the process of studying proteins?
