An inquiry-based, thought experiment to guide individuals to attain the concept of the "mole" in chemistry and how to use it in basic calculations.

1. The Mole Chemistry

2. First Something Familiar What do the following items have in common?

4. What common traits did you notice?

5. Look at these next photos and see if any would belong in the same category as the last set of photos Think about whether or not they have the same traits as you found to be common in the last set

7. Hopefully, you found that none of the photos represent a dozen Thus, they are NOT like the preceding photos that depicted “dozen”

8. Now, Something Not Familiar What do the following items have in common? Use your note-taking template to list some common traits for the examples you see

9. 32 grams of Sulfur Examples of the Mole

10. What common traits did you notice?

11. Take a Look at the Following Examples There will be columns, just like on your note sheet, that have positive and negative examples List common traits you see in the positive examples and find reasons why the negative examples are unlike the positive ones

13. Let’s share some ideas aloud…

15. Now, Take a Look at these Examples Like the last set, find traits that are similar and unlike between the groups Look for attributes that may not have appeared in the last set and compare to your working definition

21. I’m here to tell you all about moles! What they mean, how to use them and how to calculate them. Check out my diagram below, then we’ll discuss more in detail. Mr. Mole Moles Number of Particles Mass X X X X

22. Let’s Try Some Problems Involving Moles

25. Now that you’ve got down the mole concept and you’ve seen it in action, let’s to the independent practice! Rock ON
