UPCOMING EVENTS:

IDAHO FUTURE CITY COMPETITION – JUDGES NEEDED!!
Idaho’s Future City Competition is in the full swing of things and they are happy to say that they had 26 schools sign up to participate. The students are working hard on their projects and their submittal deadlines are getting nearer. They are looking for model and presentation judges to help score these portions on the day of the competition, January 10, 2009 (approx. 8-noon).

Click here for a description of what you can expect to do as a model or presentation judge. Please contact Erika Stoddard, 334-8552, if you can help. If you’d like more information on the competition in general you can find it at www.idahofuturecity.org or www.futurecity.org.


ISPE ENGINEERS – IT’S NOT TOO LATE TO PARTICIPATE
Inspire the next generation of engineers! Calling all NSPE engineers! If you missed the recent webinar "Engineer Your Outreach with Design Squad" presented by WGBH and NSPE, it's not too late to participate! A recorded version of the webinar, complete with PowerPoint presentation and videos, is available for viewing or downloading at

https://wgbh.webex.com/wgbh/lsr.php?AT=pb&SP=EC&rID=1141042&rKey=55639A624D736365

This free interactive webinar will give you all the tools you need to start up or spice up your outreach for National Engineers Week and beyond.

• Learn about Design Squad, PBS' popular engineering reality competition series.

• Find out about Design Squad's outreach campaign and FREE resources that you can use to get kids ages 9 and up excited about engineering and the design process.

• Get great tips on how to talk to kids about engineering.

• Hear firsthand from engineers about how they're using Design Squad in their outreach.

NSPE also offers resources, materials and advice on getting your Design Squad or other outreach started. Contact Stacey Ober at sober@nspe.org or Kim Granados at kgranados@nspe.org for more information.

MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's edition of the Friday Update!

Thanksgiving
George’s little brother is making a picture of a turkey to put on the refrigerator. His turkey has 5 tail feathers and he intends to paint each feather a solid color. If George has 4 colors of paint available to him, in how many ways can he paint the 5 tail feathers?
--------------------------------------------------------------------------------
Marvin’s family is having Thanksgiving dinner at their house. There will be a total of 9 people present for dinner. Marvin and his cousin, Geoff, are best friends and are insisting on sitting next to each other at the table. If everyone sits at a big, round table, in how many distinct orders can the 9 people sit? (Note: an order that can be created by rotating another order is not considered distinct.)
--------------------------------------------------------------------------------
Lillian’s favorite Thanksgiving dish is mashed potatoes. Her favorite mashed potato recipe is as follows:

7 c. cubed potatoes
6 cloves garlic
½ c. low-fat milk
¼ c. parmesan cheese (grated)
2 T. butter
½ t. salt
1/8 t. pepper

If Lillian follows the proportions of the recipe and uses all 16 cups of cubed potatoes that she has, how many cups of parmesan cheese (grated) should she use? Express your answer as a common fraction.

Answer to the last MATHCOUNTS problem:
((11 × 10^-6) – (20 × 10^-9))/(20 × 10^-9) × 100 = 54,900%

--------------------------------------------------------------------------------

The time between 10am and 11:40am can be divided into 5 20-minute segments. Thus, at 11:40 there would be 4(2⁵) = 128 = 1.28 × 10² viruses.

--------------------------------------------------------------------------------

In order to determine how many viruses fit on a pinhead we can divide the area of the pinhead by the area of a virus, but first we must put them in terms of the same unit of measure. Let’s convert diameter of each to meters.

1 millimeter(1 meter/1000 millimeters) = 1.0 × 10^-3 m

250 nanometer(1 meter/1 × 10⁹ nanometers) = 2.5 × 10^-7 m

Now we can find the area of each using A = πr²

(0.5 × 10^-3)²π = 2.5 × 10^-7π sq meters

(1.25 × 10^-7) ²π = 1.5625 × 10^-14π sq meters

Now we divide the area of the pinhead by the area of a virus.

(2.5 × 10^-7π sq meters)/(1.5625 × 10^-14π sq meters) = 16,000,000 viruses
