Teacher
After
activity:
3. Does the size of the different molecules affect its purpose or the amount
of energy needed to make it
4. What do all the molecules have in common What makes them different
from each other
What the teacher will do:
a. Ask the following questions.
1. How many valence electrons does each carbon atom have (4 electrons
or bonding sites)
2. What gives carbon the ability to form chains that are almost unlimited in
length (The amount of bonding sites on each atom.)
3. Many of the molecules in living cells are so large they are called
___________________. (Macromolecules)
4. ______________________________ is the process that forms large
organic molecules. (Dehydration Synthesis)
5. When two or more _________________ join together, a polymer
forms.(Molecules)
6. Create a table in which you compare the components and functions of
the following macromolecules: carbohydrates, lipids, nucleic acids, and
proteins. (Answers will vary.)
Extension:
Use this link to show the students the conceptual drawings of each of the different types
of macromolecules and review how the structure of each is different. (There is extra
information in the Powerpoint so focus on the four categories the students will be
responsible for.
