Good morning!
This week we talked specifically about sound waves, which are longitudinal. Students watched several videos in class, linked below:

We also talked a lot about the shape of the ear and what each section (outer, middle, and inner) do for hearing.
These ideas will be on the quiz tomorrow (Friday) on Section 1.
Today, we started Section 2 including a directed reading assignment and vocabulary words in the foldable. Have a happy week!
