Understanding Chemical Reactions and Smells

The screencast provides an overview of the 'Smells' unit in the Living by Chemistry curriculum, detailing its four sections and highlighting three challenging lessons. It covers the structure and interactions of molecules, including functional groups and chemical reactions. The video also discusses resources and safety considerations for lab experiments.

What is the primary focus of the first section in the Smells Unit?

• Alchemy and its applications

• The history of chemistry

• Molecular covalent substances and their smell

• Chemical reactions and their outcomes

In Lesson 2, what do students discover about their ability to predict smells?

• It is highly accurate

• It is somewhat limited

• It is completely inaccurate

• It is not based on any rules

What do students learn about in Lesson 10?

• Functional groups

• Chemical reactions

• Electron domains

• Ball-and-stick models

What is the focus of Lesson 15 in the Smells Unit?

• Macroscopic interactions

• Chemical reactions

• Functional groups
