Invasive species are organisms (either plant or animal) that have been introduced into a new, non-native area and spread rapidly in the new environment due to a lack of regulation by predators. Frequently, invasive species will out-compete native species for resources which can put native species at risk. This is an especially big problem for threatened habitat and endangered species, which are already at risk. Survey your area to document cases of invasive species invading a local environment. Experiment with different methods to control an invasive species (pulling invasive plants vs. using herbicides, using insecticides vs. selectively culling destructive invasive insects, trapping small animals vs. introducing native predators). You can also experiment with invasive species to document the rate of invasion, called encroachment, into a new environment. (Douce and Moorhead, 2006; NPS, 2006)
The Ask an Expert Forum is intended to be a place where students can go to find answers to science questions that they have been unable to find using other resources. If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot.

Have you ever noticed that for people with asthma it can sometimes be especially hard to breathe in the middle of a busy city? One reason for this is the exhaust from vehicles. Cars, buses, and motorcycles add pollution to our air, which affects our health. But can pollution impact more than our health? Cutting down trees, or deforestation, can contribute to erosion, which carries off valuable topsoil. But can erosion alter more than the condition of the soil? How does an oil spill harm fish and aquatic plants? How does a population of animals interact with its environment? These are questions that environmental scientists study and try to find answers to. They conduct research or perform investigations to identify and eliminate the sources of pollution or hazards that damage either the environment or human and animal health. Environmental scientists are the stewards of our environment and are committed to keeping it safe for future generations.
Zoologist and Wildlife Biologist
Ever wondered what wild animals do all day, where a certain species lives, or how to make sure a species doesn't go extinct? Zoologists and wildlife biologists tackle all these questions. They study the behaviors and habitats of wild animals, while also working to maintain healthy populations, both in the wild and in captivity.
With a growing world population, making sure that there is enough food for everyone is critical. Plant scientists work to ensure that agricultural practices result in an abundance of nutritious food in a sustainable and environmentally friendly manner.
Park rangers are the law enforcement officials of our state and national parks. They protect and preserve parklands, keeping park resources safe from people who might try to damage them, deliberately or through neglect, and keeping people safe from dangers within the park. To achieve this goal, park rangers work in a wide variety of positions, including education and interpretation for park visitors, emergency dispatch, firefighting, maintenance, law enforcement, search and rescue, and administration. There is a large global shortage of park rangers in developing countries.
