Day 1 Pre-Class Podia Problem: Describe Chemistry

In most pre-class assignments we will include a Podia question that may require numerical, text, and/or image-based responses. Each pre-class Podia question is based on the pre-class material and working through the pre-class material will help you formulate your response. Consider the problem and write down/draw out your solution in your class notebook.

Two days before the next whole-class session, the pre-class Podia question will become visible in Podia (within the “Whole Class” section), where you can submit your solution. [For example, the Podia question in a Wednesday pre-class assignment will open by Monday evening.]

When you come to the next whole-class session, the class leader will choose one or more student-submitted solutions and explain why they are (or are not) effective scientific statements. These questions are designed to hone your skills so that you can solve mastery problems you will encounter on exams.

Click on the relevant open Podia question and submit your answer there. Your submission to instructor-opened questions will be anonymous to your classmates, and you can only view your own submission. (If you make a separate post, you will not be anonymous.)

You may find Podia sign-in instructions here.

Your first pre-class Podia question is designed to help you learn how Podia works. Write a short sentence about chemistry. Accompany your sentence with an image (sketched by you) that you think is a good example of chemistry. See whether your class leader selects your submission as a good one to show (anonymously) to the class.
