Absent Students
Today we worked on our earth's interior models. Please work on this.

Handouts
You did not receive any handouts today.

Homework
Earth's Interior Model (see Handout 79) due in class on Friday, February 27th. No corrections are offered and no unexcused late work will be accepted.

Absent Students
Today we finished handout 78 and began handout 79. You need to:

1. Complete handout 78 (contact a friend for the answers).
   
2. Complete steps 1 and 2 of handout 79.

 - Handout 79: Modeling Earth's Interior

Homework
- Investigation 3.3 reflection corrections due tomorrow by 8am to Schoology.
- Bring colored pencils and a ruler to class tomorrow.

Absent Students
Today we did an activity where we tried to figure out what was inside a plastic egg without opening it (Handout 77). Then, we read background information on how we know what's in earth's interior (pp. 72-73 in the XPT book). Finally, we took some notes from a animated slide show that described the four layers of earth's interior (handout 78, page 1 only). Here's what you need to do:
 - Download handouts 77 and 78.
 - Read pages 72-73 in the XPT book.

Handouts
You received two handouts today:
 - Handout 77: Lesson 5 Getting Started
 - Handout 78: Earth's Interior

Homework
Investigation 3.3 reflection corrections due Wed., 2/25 by 8am to Schoology.

Absent Students
Compare your answers to handout 75 to the class answers (below). Then, completed questions 1-3 on handout 76. Use the link to the USGS site (below) to look at earthquake patterns. Click on the gear in the upper right and select 30 days, 2.5+ earthquakes so you can see the pattern.

Homework
Investigation 3.3 reflection due to Schoology by 8am, 2/20. See Schoology for full details and requirements.

Absent Students
Finish handout 73. Read step 8 on page 43 in the XPT book for information on how to use the graph on page 41. You must have the data table on page 2 of handout 73 completed. If you have a compass at home, print page 3 of handout 73 and complete it. Or, if you know how to draw circles of a certain radius on your iPad, do that with the digital form of handout 73.

You did not receive any handouts today.

Homework
Write a summary/procedure on how to find the epicenter of an earthquake. Full requirements listed in Schoology (see XPT Investigation 3.3 Reflection). Upload your product to Schoology by Friday, February 20th at 8am.

Absent Students
Today we discussed how to find the epicenter of an earthquake, reviewed handout 71, and started handout 73. Here's what you need to do:

1. Think about what information you need to find the epicenter of an earthquake. Think back to handout 72!
2. Read pages 38-39 in the XPT book.
3. Finish handout 71.
4. Complete all of question 3 on handout 73. Use pages 40-41 in the XPT book to help.

Instructions to the Students
Hello possums!

As I'm soaring through the air at a whopping 830 km/h to the AAAS conference, you'll be learning how to find the epicenter of an earthquake. I need you to download handout 72 below to Notability and then return to this page. Go ahead. I'll wait.

Okay, so now that you've got the handout, here's what you're going to do. You will open the link below. Read all of the information on the page before continuing to the next step. This site will teach you how to find the epicenter of an earthquake. It will do all of the math for you (yay!), but you have to provide it with the correct data for it to do that.

Please take your time with this activity and read everything carefully. Small errors in your measurements will not help you. Seriously. This site is picky! And for good reason: you need to make accurate measurements in science. If any of your measurements are too far off, the site will let you know, but only at the end of the process. Then, it will make you start over again! So, take your time, measure carefully, and input the accurate data.

Your goal is to find the epicenter of one earthquake. However, if you still have time remaining, continue practicing locating the epicenter! Part of the lesson 3 reflection will be telling me how you find the epicenter. The more you practice, the more you'll become familiar with the process.

If you finish all four locations before the end of class, please work on corrections, do homework for another class, or go learn more about some historical earthquakes.

Have a great 3-day weekend and I'll see you all on Tuesday.

Mr. Ower
