Science Fair Project Idea
Farmers face a variety of challenges in their efforts to grow crops. One of the chief challenges is the presence of unwanted plants (weeds) that compete with the crop plants for water, nutrients, and light. If the weeds are not suppressed, they can reduce or completely eliminate the amount of food derived from the crop at harvest. In this biotechnology and plant science fair project, you will simulate the competition between crop plants and weeds, and determine whether the use of an herbicide,… Read more

Science Fair Project Idea
Antlion larvae are known for their predatory ways. In sandy areas, they dig pits to trap ants or other crawling insects that happen to stumble in. This project shows you how to create a mini-environment for antlion larvae to test their preferences for pit-building sites. Read more

thumbnail If you have a garden, you probably know about snails (or their shell-less relatives, slugs). You may even be looking for a good way to keep them from getting into your garden and eating up the results of all your hard work. In this science project, you will take a scientific look at one method of discouraging this garden pest. Read more
Zoo_p019

- Less Details
Time Required Average (6-10 days)
Prerequisites None
Material Availability You should only do this science project if you live in an area where you routinely see land snails or slugs. Land snails and slugs are most likely to be out and active when it is damp out (such as in the early morning or after it has rained), or you may find them hiding under plant leaves.

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

Science Fair Project Idea
You might not know it, but a lake without algae would be a very dull place. If there were no algae, there would be no small animals feeding on the algae, and there wouldn't be any fish eating the small animals that eat the algae. You might conclude that since some algae is good, more algae is even better, but algae growth has a down side. If there is too much algae, they can deplete the oxygen in the water, killing off other species in the water. What is one culprit that leads to algal growth?… Read more

Time Required Very Long (1+ months)
Material Availability You will need access to a pond or a lake from which to collect water. Students who do not have access to a pond or a lake might want to look at some of the variations, at the end of the project, which use purchased algae cultures.

Safety Adult supervision is recommended.

thumbnail Every day farmers around the world apply commercial fertilizer to their fruits and vegetables to improve plant health and yield. But applying commercial fertilizer is expensive and not economically possible for some farmers in developing countries. What if they could find a way to fertilize plants cheaply? It turns out that human urine is rich in the nutrients that plants need to grow. Could urine serve as a fertilizer substitute? Find out for yourself in this plant growth science project. Read more

Science Fair Project Idea
thumbnail Interested in helping the environment, and don't mind getting dirty? In this project you get to mix it up with earthworms, soil, and various types of organic kitchen scraps. The basic idea is to set up small earthworm colonies to compost different types of food waste. You test the soils in each type to see how diet affects both the earthworm population and the nutrients they put back into the soil. This project takes a little time, but it's worth it. You'll help the environment and learn… Read more

thumbnail Native plants are important for both ecological and medicinal reasons. However, most native plants are not very well studied. One way to know more about these plants is to understand which other species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a native plant and use this information to determine its evolutionary relationship to other species of plants. If the plant you chose has not been sequenced before, you can… Read more

Time Required Long (2-4 weeks)
Prerequisites High school biology class; familiarity with using the PCR machine and gel electrophoresis equipment, and/or using the equipment with a mentor.
Material Availability You will need specialized pieces of equipment, including a PCR machine (thermocycler) and a gel electrophoresis apparatus. If your school does not have this equipment you might want to seek out a mentor at a junior college, university, or biotechnology company. If you have the resources you can do the DNA sequencing yourself, otherwise you can send the samples to Dr. Baysdorfer at California State University, East Bay, see Experimental Procedure for more details.
Cost High ($100 - $150)
Safety This project uses ethidium bromide, which is a carcinogen. Always wear gloves and safety goggles when handling. Dispose of the ethidium bromide according to your school or institute's hazardous waste protocols. If you have concerns, ask your teacher or mentor for advice.
