  19. Monomers and Polymers: In Our Own Words • Your Task: • Work with your partner from yesterday’s Hamburger activity to describe how monomers and polymers relate to each other. • (remember, this is a “part/ whole” relationship where monomers are part of the wholepolymer) • You can express this as: • A Written analogy w/ a picture • (i.e.: monomers and polymers are like _______ and _______, because _________) Or… • A rap/ song/ poem describing how monomers relate to polymers • Objectives for Class: • Identify the 6 key elements found in living things • Explain how monomers and polymers relate to each other

  47. Lab Skills Pre-Assessment: Making Data Tables Overview: • One important skill in designing and conducting lab experiments is to create a data table that serves as an organized way to collect the data from your experiment. Purpose: • To practice making data tables that are both organized and appropriate for a given experiment. • This is important preparation for our McMush lab at the end of this week, and will give your biology teachers valuable feedback about how well you are able to accomplish this task on your own. Instructions: • Read each experiment description, then draw a data table in the space provided.
