Students will be able to describe and draw large molecules (polymers), such as proteins, nucleic acids, and starch, showing they are actually formed by repetitive combinations of simple subunits.

Students work in small lab groups (2-3 students) to complete a Slime Lab. They will use a solution of polyvinyl alcohol to make a gel (slime) by adding borax solution, which creates cross-links between chains. Students will then do some tests on their slime making observations of the properties of slime. Students will document the process of making slime in pictures with their cell phone and use these pictures to complete the lab assignment on Google Docs.

2 Direct Instruction

Students will watch a video I created and posted on www.sophia.org. After watching the video they will take a short quiz on Google Forms. This will give me an idea of what students need to cover in class.

3 Guided Practice

After guided practice students will work on a Molecule Building lab. Working in small lab groups, students will follow lab instructions to build 30 molecules with a molecule kit. When the group builds a molecule they will take a picture of it and add it to the Google Doc lab report.

4 Independent Practice

Free, Paid

Using the picture students took of their largest molecule (Glysine - NH2C2H3O2) students will use Thinglink to label all the bonds and groups of the molecule.

5 Wrap-Up

Activity: Creating

At the end of the unit students will work in small groups to create a Aurasma hotspot in the classroom. Students will draw and color a stick and ball diagram of an assigned molecule. They will then create a short (>1 min) video explaining the functional groups of the organic molecule. These drawings will be placed around the room for other students to review using the Aurasm app.
