Description
Download IRIS one-pager, "How are earthquakes located?"  Download interactive Flash animation that uses a simple model using the arrival times of P and S waves to learn the location of an earthquake epicenter. Although computer algorithms using P wave arrivals are used by scientists today, this method is valid for introductory lessons. Download PDF background information and links to short video lectures that help understand the method.

“Worksheet that briefly looks at the economic and environmental impact of drinking bottled water over tap water. Bottled water companies haul billions with marketing campaigns that describe the stuff as pristine, natural and being better than tap water.”

Save Class Time:  Become a Video “Stringer” Ever show a YouTube video? Several in a row? If that takes time (which it does!), then this link is for you:.  Learn how easy it is to string a short or long series of videos together. Now there’s no waste of class time or your time – your clips will play AUTOMATICALLY from video to video. Show a non-example, then a good example in order to distinguish and clarify your learning objective – however you want to string videos together. Have fun!

Create a Valley Glacier

Description
Where in a valley glacier does the ice flow fastest and where does it flow slowest? Make gawk that will represent an alpine (valley glacier) and Use the gak to predict where in the glacier ice flow will be fastest and slowest.

Materials: Gak recipe, Glue, Borax solution premixed and in beakers for easy pouring, graduated cylinder, spoon, zip lock baggies, wet erase markers, plastic cups, blocks, tape (to hold it to cup)

Procedure:
Part 1 -  Mixing the Glacial Gak
1) 50 ml of glue has been pre-measured into the baggie.
2) Measure 30 - 35 ml of water with a graduated cylinder.
3) Add the water directly to the baggie that contains the glue and stir well.
4) Measure 30 ml of Borax solution into a graduated cylinder.
5) Add directly into the baggie and stir vigorously until it gets together.
6) Close the bag tightly and knead the glacial gak inside the bag with your hands.

Part 2 -  Use the gak to make a model of an Alpine Glacier (Valley Glacier)

Roll up your sleeves and take the glacial gak out of the baggie and knead in your hands until smooth.  Put back into the baggie.
The plastic cup represents a valley in which the glacier is flowing down.  Put the ‘glacier’ (glacial gak) into the plastic cup as shown by your teacher previously.
On the surface of the ‘glacier’ a little bit back from the leading edge, draw 5 dots with a wet erase marker about an inch in from the front and connect points with a line that will
represent metal stakes in the ice (see figure)
Draw a second line of 5 dots further back (about 3 inches in)
on the glacier (see figure)
Prop the back of the cup up on a block so that the front of the cup (valley) slopes downward and gravity can help the glacier flow forward.
Tape the cup to the block and observe the glacier flowing slowly downhill.

Finding Inner Peace
Suggested by
Tim Wozniak
Description
“I am passing this on to you because it definitely works, and we could all use a little more calmness in our lives. By following simple advice heard on the Dr. Phil show, you too can find inner peace. Dr. Phil proclaimed, "The way to achieve inner peace is to finish all the things you have started and have never finished."

So, I looked around my house to see all the things I started and hadn't finished, and before leaving the house this morning, I finished off a bottle of White Zinfandel, a bottle of Bailey's Irish Cream, a package of Oreos, the remainder of my old Valium prescription, the rest of the cheesecake, some Doritos, and a box of chocolates, and a half bottle of scotch and of course a couple of shots of tequila.

You have no idea how freaking good I feel right now. Pass this on to those whom you think might be in need of inner peace.”
