Macromolecule Jigsaw
Download as PPT, PDF0 likes886 views
A polymer is formed from smaller molecules called monomers linking together. For example, individual BART train cars are like monomers - when joined together they form a full polymer train. Students were assigned different macromolecules to research - including the monomer, description, examples, uses by cells/organisms and key points. They had 25 minutes for research. Then students spent 20 minutes doing a gallery walk to copy down notes on each macromolecule from the other groups. They were to answer review questions and list the four main macromolecules, their functions, monomers, and the connection between polymers and monomers.

Macromolecule Jigsaw
- 1. Launch What is a polymer? What is a monomer? Come up with an analogy for the formation of a polymer from monomers. (example. One BART car is like a monomer. Together, many BART cars make a full train, which is like a polymer)
- 2. Jigsaw I will come around and tell your group what macromolecule you will be doing You have 25 minutes Take notes on the following: Name of monomer Description of macromolecule Examples Uses by the cell/organism At least 1 other key point
- 3. Gallery Walk You have 20 minutes to go around and copy down the key points and questions that pertain to each macromolecule
- 4. Practice: Answer all questions on the back
- 5. Summary Checklist List the four main macromolecules (polymers) Choose 1. List the function/use/example. Connection between polymers and monomers List the monomer for each macromolecule
- 6. Practice : Complete review sheet on back of handout On a separate sheet, answer the questions posed by each group
