G7 Week 10

Last week in science!

Monday, November 5th

Today in science: Students finished ‘mining’ a BBC documentary to both deepen and sharpen our knowledge and understanding of soil. More specifically, they finished watching “Deep Down and Dirty – The Science of Soil” to help answer three key questions:

1. What is soil?
2. How is soil formed?
3. What is important about soil? In other words, why does soil matter?

In addition to these three key questions, students were also asked to collect vocabulary words used throughout the video to help them learn the language of soil science. The vocabulary words we collected can be seen in our Notes Portal. To facilitate our ‘mining’ of this BBC video, we will used this document.

Homework: There is no science homework tonight.

Tuesday-Friday, November 6-9th

Today in science: The main themes for these lessons were “soil formation” (otherwise known as pedogenesis) and “physical weathering.” Here is a copy of the notes used by Dr. M at the start of this sequence of lessons. Mainly through the use of highlighted notes posted to the Notes Portal, students were asked to illustrate eight types of physical weathering on a large piece of A3 paper provided to them by the teacher. These notes contain many links to videos aimed at helping students imagine and understand each of the eight types of physical weathering we’re studying. The eight types are:

1. gravity
2. ice wedging
3. temperature stress
4. abrasion by stream/river
5. abrasion by wind
6. abrasion by waves
7. abrasion by glacier
8. salt

Prior to making their drawings on the A3 paper, students were strongly encouraged to list the key words and phrases for each type of physical weathering process and create symbols for each of them on a smaller piece of A4 paper. This step was meant to help students improve the quality, accuracy, and clarity of their final A3 drawings.

Homework: Students have been asked to complete all eight of their physical weathering drawings before the start of Monday’s science lesson.
