The study guide and podcasts are up for Lesson 6.
There are two podcasts for this lesson. The first is for page 72, which falls between the two investigations we will perform this week. The second covers the reading from pages 76-79. The study guide covers all of Lesson 6 (and both podcasts).
I do a little more guiding in these podcasts, because the material is a little more complex this time around. I also try to clarify when wording might be confusing in the text – for example, the text uses "lighter" in place of "less dense" and I do not consider them the same. I hope you find the explanations helpful!
