At the middle school level, there are many academic clubs in which students can participate. Students
can choose clubs that focus on an area of interest.
Mathcounts Club
Mathcounts tries to increase excitement towards mathematic achievement. It hopes to provide students
with the foundation for success in science, technology, engineering and mathematics careers. Schools select
individuals and teams to participate in competitions. Local competitions are held in February with winners
progressing to state competitions and then on to the national level. Mathcounts works to challenge student's
math skills, develop selfconfidence and give rewards for their achievements.
Envirothon
The Envirothon program focuses on natural resources knowledge and exposes students to diverse
environmental issues, ecosystems (生态学). The ecology field competition for five-member middle school
teams offers competitions in wildlife, soil, forestry, and current environmental issues. Students work and
learn in middle school clubs and can compete at the local and state level.
Future Problem Solvers
Future Problem Solvers is an academic club that uses a six-step process to solve problems that may
happen in the future. Students who are in the talented and gifted program, who like to"think out of the box",
or who enjoy thinking about futuristic problems may like this club. Teams made up of four students read
future scenes and write up solutions in a booklet using the six-step process. Teams that score high enough
can go to the state competition and then to the international competition.
Builders Club
Builders Club is open to any middle school student who wishes to perform community service. Each
Builders Club is co-sponsored (共同捐助) by a Kiwanis club and the middle school. The members learn
by doing, and they learn organization, teamwork, and leadership. Builders Clubs can sponsor a "Teacher
of the Year" program, provide a recycling collection point, organize canned food and clothing drives to
support local shelters.
Middle school academic clubs offer students a place to explore interests or talents. The clubs they join
in middle school can help guide choices in high school and beyond.
