Ideas for Spirit Week

All right, at my school, we have two spirit weeks run by the student council (or at least we used to, things are changing now). There are about 260 students in the school (7-12). But anyways, since we don't have a football team - we wait until February to have Homecoming, and instead, to support Girl's Basketball (in the fall) we have Halloweek! Here's the sum of the past year's events for both weeks - hope you can use some of the ideas!

Halloweek: The week of Halloween of course!
Each day we would have a dress up day, these days include:
Green & White Day (school colors)
Grandparents Day (dress up as old people :))
Halloween Costume Day (sometimes we awarded prizes for the most creative, etc.)
Summer Fun Day (usually we have snow by this time so it's quite interesting)
Twin/Triplet/Quadruplet Day (students try to dress as much like another)
Sports Day (wear school attire- basketball jersey, cross country...)
Cartoon Day (dress up like your favorite cartoon)
Rock Star/Diva Day (dress up like rock stars, divas...etc.)
Whatcha Lookin' At Day (dress kooky - mismatching socks, just different stuff)
Semi-Formal Day (Wear dressy clothes)
Class Color Day (Each class had their own color- we usually did this on Friday when we had our games assembly because it would look soo cool!)

We always have class competition - one class wins spirit week (with the most points) and they get a pizza party. We tried many different ways of 'counting' dressing up, but then decided at random we'll select one student from each class, if they are dressed up the class gets points, but if not, then they don't.
We also have other activities throughout the week. These include:

Mural Design- We required each class to create a mural/poster that promoted school/class spirit. We had set rules and things they should include. (E.g. My class theme was "Jeffers Sophomores Soar Above the Competition" and on the poster we had a basketball player shooting over a rival school to a basket) We hung these posters in the gym for the remainder of the season.

Window Design- Sort of another poster, but this one had to include Halloween. My class design was "Scare away those Cats and Dogs" because we played the Bulldogs and then the Panthers that week. And had a ghost saying boo to a cat and dog.
Both the Mural and Window Posters we judged by a panel of parents and the highest rated posters were given more points and so on.

Pumpkin Carving Contest- Student (Classes) were not allowed to carve pumpkins on school grounds, but did them at home. We put candles in them and displayed them during a home basketball game that landed on Halloween.

Scarecrow Contest- Groups of students from any grades or students alone could create a scarecrow (following guidelines). The scarecrows were also judged and the top three winners received money.

Penny War- Each class had a bucket/pail for money. Covers were put on so classes could not see how each class was doing (made it more interesting). Pennies were good for a class, and opposing classes would put silver into other classes canceling out the pennies. (E.g. the juniors had 20 dollars in pennies in their jar, but had 16 dollars worth of silver, their net total would be 4 dollars.) In the end the class with the most earned points (well all the classes did but they got the most points.) The winning class also received 1/3 of the total money, 1/3 went to the student council fund, and 1/3 went to a charity of the student council's choice.

Pack the Gym- To get more people to the games, we had a thing called Pack the gym - the class that had the largest percentage of their class there was awarded the most points. Sometimes we did things if it was a home game like pack the gym with white - whichever class had the largest percentage of their class there wearing white got the points.

Candy- Guess how much candy is in the jar - $.10 or $.25 for each guess. The winner got the money and the candy.

Dance- we always end our week with a dance. Our dances are well known and we have guest passes for students that have friends at other schools that want to come.
