September 22-26 - The Hole in the Ozone Layer Week

Here is a link to information about the big hike on October 5 -> Big Hike!
Unfortunately, the site doesn't open on some mobile devices.

(We are starting Unit 2 today.) Classes are a bit shorter today due to early release (every Monday). Benson will go over the lab that we did on Friday and then we will discuss several factors that influence the flight of a baseball or football. If you were gone, carefully read this web page and pages 479-480 in your text (honors pages 466-467). Honors students: MESPOWs for this week are #1 and #29. Read them both carefully and choose one to do with the WS.

Students will listen and take notes as Benson explains "The Hole in the Ozone Layer". If you were gone, get a copy of the notes handout and copy the notes from a classmate, read this web page and watch the video of the week below.

Benson will show students a demonstration, and then students will continue to take notes and learn about the hole in the ozone layer. If you were gone, copy the notes from a classmate and read this web page and be sure to select the arrow to watch the change over several years.

We will do a quick review and then students will do an introductory lab activity to help them understand experimental design.

We will have a notebook entry and then Benson will explain the UV Bead Project. Watch this video -> How the Sun Sees You Students will have time to start working on their projects. Here is a description of the project-> UV Bead Project

Question(s) of the week: What causes the hole in the ozone layer to appear over Antarctica every September through November? Why does the hole affect the rest of the world?
