Weed Science looks at one of the most important environmental issues in Montana. Weed science is the study of how unwanted plants grow, interact with other plants and animals, and respond to management. Through this project, develop knowledge and understanding of natural resource ecology and the interaction between nature, agriculture and recreation. Learn how to make a plant press, the science of weed control, various methods for controlling weeds, the impact of invasive plants, and how to monitor changes in the land. Study how weeds use different dispersal methods, learn why weeds are fierce competitors, and explore careers.

Weed Science, Level 1

Beginners will learn about weeds with fun and hands-on activities. You will begin by making a plant press and collecting at least 25 weeds. You’ll also learn about how weeds reduce wildlife habitat, develop alternative uses for weeds, learn about weeds in your garden and explore the roots of weeds.


This level has 14 activities that must be completed before moving on to Level 2, in addition to one “more challenge” option. Work at your own pace, but complete the level in three years. Additionally, it is recommended to build the plant press during the first year and collect at least 25 weeds by the time you finish the level.
