Lesson 1 - Monday, Sep 29
Housekeeping: Students
1. QW#4
2. Returning to INV#1, we began by examining data–including both student drawings and photos–collected during last week’s Crystallization Lab. Dr. M expected students to have formatted all investigation data prior to the start of today’s lesson, but was disappointed to see that many students had not done so despite a request last Thursday/Friday to do so.
3. In B period, we examined Student 8B’s well-formatted photos and attempted to formulate conclusions about the effect of the temperature at which magma is allowed to cool on the size of the crystals formed. After doing so, however, we realized we had made our class conclusions from the results of only one student’s data!!! We determined that we needed to examine ALL B period student’s data in the next lesson to see if the class data converges on a single, clearly visible conclusion.
4. In H period, we examined Student 2B’s drawings AND Student 8B’s well-formatted photos and attempted to formulate conclusions about the effect of the temperature at which magma is allowed to cool on the size of the crystals formed. When doing so, however, we realized that we don’t really know how a ‘properly’ formed salol crystal might appear on a glass slide. We then consulted an ‘expert’ slide and realized something total unexpected but very important: By using microscopes to examine our crystals we prevented ourselves from seeing the full crystals and thus prevented ourselves from describing the actual relationship between cooling temperature and crystal size.
Homework: Any student who hasn’t formatted their investigation data in their Science Notebook should remember to do so prior to the start of the next science lesson.
Lesson 2 - Tue, Sep 30 (B) & Wed, Oct 1 (H)
Housekeeping: Dr. M asked students to add three high-quality images showing the ‘ideal’ results of magma (salol) cooling at three different temperatures (cold, room, and hot) to the INV#1 entry in their Science Notebook.
1. By using a combination of some images of three different iron crystals, students’ thoughts about QW#4, and three high-quality images showing the results of the magma (salol) crystallization investigation, Dr. M asked students to begin creating a new, updated version of our Unit 7.1 model. We did this by drawing our ‘new’ version of the Earth on a blank sheet of A4 paper.
2. B & H periods also received their graded RA 5 (Moving rock) assignments as they were done on a (paper) handout.
Homework: There is no B period homework tonight, but Dr. M asked H period students to complete the remaining part of their “Rocks & Minerals” Flow Chart (which students should already have half-completed in Notability). For H period, this assignment is due on Friday and students have been asked to submit a copy of their completed Flow Chart to the Google Science Classroom.
Lesson 3 - Wed, Oct 1 (B) & Thu, Oct 2 (H)

The DRIVING QUESTION of our current unit is: How does the Earth recycle and remake the materials of our planet, from the deep core to the surface we walk on?
