Landscapes and Water Usage *
AbstractSome plants use a lot of water, and some are very drought-tolerant. Drought-tolerant grasses are good for water conservation because they require less water to grow and stay green. How much less water do they need? Which types of grass are drought-tolerant? You can buy different types or brands of grass seed at your nursery that claim to be drought-tolerant. Grow them in a container and then starve for water after they are established. Which brands die out first? You can conduct a similar experiment using sod, or lawns that are already established with different species of grass. Just make sure to get permission from the owner first! Then you can mark off your study area with stakes and starve the area for water. Which types of lawns are the most drought-tolerant? What about other landscape plants? Are native plants more drought-tolerant than exotic plants? You can actually calculate the amount of water that each type of plant needs, then compare the water needs of different plants. How much water can drought-tolerant plants save annually? Can you extrapolate this to estimate the amount of water that can be saved by an entire community? A city or regional park? Can you propose some good plants for landscapers to use that will save water? (National Arbor Day Foundation, 2006; WMC, 2006; NPS, 2006)

Ask an ExpertThe 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.

Landscape ArchitectHave you ever visited a new city and marveled at how nice looking it was? Perhaps the streets were wide, the public places were well organized, and the parks and gardens were green and had lots of attractive plants. Well, what you experienced was a well-balanced and designed landscape plan put together by a landscape architect. Landscape architects design everything that is outside of buildings. Their goal is to make a design that is functional, but one that is well balanced with nature and in which people feel happy and comfortable. Landscape architecture is the perfect blend of engineering, art, and nature. Read more
Soil and Water ConservationistSoil and water are two of Earth's most important natural resources. Earth would not be able to sustain life without nutritive soil to grow food and clean water to drink. Soil and water conservationists foster the science and art of natural resource conservation. The scientists work to discover, develop, implement, and constantly improve ways to use land that sustains its productive capacity, and enhances the environment at the same time. Soil and water conservationists are involved in improving conservation policy by bringing science and professional judgment to bear in shaping local, state, and federal policy. Read more
Plant ScientistWith 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. Read more
Environmental ScientistHave 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. Read more
