September 26-30

IMPORTANT - Period 1-4-5 students have one week to come in (before school, at lunch, or after school) to make corrections on their tests. They can use their notes and handouts. Honors students can make corrections if their score was less than 70%, and can only raise their score to 70%.

Students will do a lab called "Burning Up the Atmosphere". Honors students: MESPOWs for this week are #1 and #29. Read them both carefully and choose one to do with the WS. If you were gone, periods 1-4-5 should do questions 1-10 on page 499 . . . periods 6-7 should read 472-477 and questions do questions 1-2 on page 478.

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). 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. Then watch this 4.5-minute YouTube video.

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?
