Project Idea
thumbnail Whiteflies are a group of closely related insect species whose larvae live on plants. Like aphids, they suck nutrients from the plant's circulatory system. What is the most effective method for fighting a whitefly infestation in your garden? This project has some ideas for you to try. Read more

Project Idea
thumbnail Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more

Project Idea
Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… Read more

Safety Use caution when using a blade to cut open seeds. Adult supervision is recommended.
Project Idea
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… Read more

Project Idea
Mushrooms are not plants, but are fungi. Fungi include mushrooms, molds, and lichen. They do not produce seeds to reproduce like some plants. Fungi produce spores, like more primitive plants do. The spores of a mushroom are contained in the tiny folds around the stem underneath the mushroom cap. Different species of mushrooms have different types of spores, with different colors and different patterns of folds. You can make mushroom prints by removing the stem from a mushroom and placing the… Read more

Time Required Very Long (1+ months)
Prerequisites None
Material Availability This project requires access to a place where mushrooms grow wildly (and you have permission to harvest them) or the purchase of a mushroom growing kit from an online vendor.
Cost Low ($20 - $50)
Safety Do not eat any mushrooms that you find growing in the wild.
Project Idea
thumbnail We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day…", or the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many? Because we humans understand how important rain is to our well-being. Rainfall, as part of the water cycle, brings water back to Earth that had previously evaporated or transpired from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain, it… Read more

Time Required Very Long (1+ months)
Prerequisites Before starting this project, check your local and state laws regarding the rules for collecting rainwater.
Material Availability Readily available
Cost High ($100 - $150)
Safety Wear safety goggles and equipment when working with tools. Minor injury is possible. Adult supervision is required. Do not drink the water collected in the project.
Project Idea
Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

Time Required Long (2-4 weeks)
Prerequisites None
Material Availability Duckweed can be purchased from plant nurseries, or you can also find it growing naturally in local ponds and marshes. If you find the duckweed in a local water source, make sure you get permission from the land owner or town before taking any.
Cost Low ($20 - $50)
Safety No issues
Project Idea
Do your parents like to garden? Then you might have a beautiful lawn surrounded by flowers, or a vegetable garden. Humans have been introducing plants to our landscapes for centuries, which has dramatically altered the natural habitat of many environments. Chances are, the landscape you live in is not a natural landscape. One movement is to restore these habitats by re-introducing native plants. Conduct a survey in your area looking for native and non-native plant species. You can take… Read more

Some 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… Read more

thumbnail Do you have bats in your neighborhood? Have you heard them "whoosh" by you, but not been able to see them? In this science fair project, you will be able to detect flying bats by listening in on the ultrasonic signals they produce to locate objects in their environment. The bat detector is a useful and fun tool for studying the biology of this nocturnal flying mammal. Read more

- Less Details
Time Required Long (2-4 weeks)
Prerequisites Provide a brief description of requirements: Since this project involves studying bats in their native environment, you should start this project only if you are confident you have bats in your neighborhood. Ask your science teacher if there are local bats that you can observe.
Material Availability You will need to purchase a bat detector for this science fair project. See the Materials & Equipment section for more details on where to purchase one.
Cost Average ($50 - $100)
Safety For this science fair project, you will be listening to bats as they fly near you. You will not be touching them or disturbing them in any way, so there are no safety issues. However, if you do see a bat on the ground, do not touch it because bats can carry dangerous diseases.
