Washington State Mathematics Council High School Mathematics Contest - Team Project 2009 Grow Beasts!

This wiki space is meant to be a place where participants in the WSMC Team Project portion of this year's Regional and State Math Contests can communicate, share data, exchange ideas, consult with one another and so forth. Each team is free to create their own page or pages but there is also a common area where teams can post information or pose questions that may be of interest to all. The idea is to build the best possible mathematical models for the growth of the Grow Beasts.

Be sure to visit the [|contest Web site.] It contains a thorough explanation of the contest requirements and includes links to some important resources including the [|scoring guide]. It also contains instructions on how to register (Free!) your team for participation in the contest.

In order to use this wiki space, you must have a (Free) wiki space account. (Look in the upper left portion of this page for the link.) Then you will be able to request membership in this particular wiki space. If your name and e-mail address have been sent to Mark Roddy (mroddy@seattleu.edu) by your team coach, your request will be accepted soon and you will be able to edit the pages (and add new ones) in this wiki space. A beginning page will be added for each team in the contest. **Click [|HERE] for a pdf file with some directions for simple editing of wiki pages**. Please be aware that an automatic log is made of all edits made to this site. Inappropriate content will be removed and may result in a team's disqualification.

__**3-23-09**__ Our State Contest Grow Beast was grown in 500 ml of water and 22.5 milliliters of lemon juice.

__**3-20-09**__ The information on the Grow Beast for the state math contest team project will be published here (and on the contest Web site) at noon on March 23rd. The scores tied to the predictions will come from the accuracy of the predictions made with respect to the state contest Grow Beast. The predictions made with regard to the regional contest will not be a factor in the calculations for the state contest.

__**2-27-09**__ The Grow Beast is growing!

 * __2-23-2009__** The Team Project Grow Beast is in the water - salty water! He or she took the plunge at noon today into a solution composed of 15.6 cc of iodized salt added to 500 ml of water and maintained at a comfortable 25 degrees C (+ or - 2 degrees C). The Grow Beast went in at a svelte 4.7 cm but is slowly swelling and will continue to be allowed to do so for 96 hours from the time of immersion. Has anyone figured out why I used 15.6 cc rather than, say 15 or 16cc?

__**1-16-09**__ **VERY IMPORTANT!!** __**In order to accommodate WASL testing the date of the Regional Contest Grow Beast Growth** **has been changed from March 2nd to February 23rd. That means that you need to have your work in preparing the mathematical models done a week earlier.**__ - Mark Roddy

__**1-13-09**__ For salt, let's all use Morton's Iodized Salt, also widely available. If you can't find any, let me know and I will get some to you. - Mark Roddy

__**1-8-09**__ In the effort to control variables, we should all be using the same kind of lemon juice. Please use Sicilia Lemon Juice "Squeezed from Fresh Lemons - Not from Concentrate." I found that this is widely available, for example, at Safeway. The bottle looks like this and is generally found near the lemons in the produce section. If you can't find any, let me know and I will get some to you. - Mark Roddy


 * __1-6-09__** I made a few slight changes to the [|contest Web site], updating the text to clarify a few point regarding the models to be created and the way in which the report and predictions are to be made. Please take a look and let me know if you have questions. - Mark Roddy
