Molecular Formulas

For our first lesson of Unit 2, students were asked to respond to the following entry task:

  • What do you think is happening when you smell something?
  • Why do you think we have a sense of smell?

After a class share-out, we worked through the Lesson 28 PowerPoint and then students all participated in an activity (guided by the  Lesson 28 Worksheet) where they smelled five different scents and then compared their observations as a class.  Based on the class results, students made connections between molecular formulas, chemical names, and scents (fishy, minty, or sweet).  Remaining class time was used to read and summarize Lesson 28 from the textbook.

Extend Your Learning!

While not necessarily related to smells, students are encouraged to check out the NASA InSight Mars Landing feed starting at 11:30 this afternoon.  InSight is scheduled to touch down on Mars at 11:47 AM PST (according to a recent article in Forbes).  On-demand video recordings will be available after the landing completes.
