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.

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.

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 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
