Acid rain and the survival of fresh water guppies (Poecilia reticulata)Featured science projectScience project video
The mortality rate of fresh water guppies (Poecilia reticulata) increases as the acid level in the water increases.
Difficulty: Elementary school
The concentration of lead content in drinking waterFeatured science projectScience project video
This experiment was performed to ascertain the concentration of lead content in the tap water of new houses (less than 10 years old) as compared to houses which are more than 50 years old. These older houses should still be using lead pipe plumbing.
Difficulty: Middle school
Boatyards and marine pollutionFeatured science projectScience project video
This science fair project is performed to compare the level of marine pollution (specifically, copper leaching) at a boatyard with pollution in other locations. The testing was done at an independent lab using water samples obtained from a boatyard, a marina, a beach and tap water.
Difficulty: Middle school
Effect of oil spills on aquatic plantsFeatured science projectScience project video
This science fair project was performed to find out how oil spills will affect aquatic plants. Testing was done using hydrilla plants in water with and without a layer of oil covering the surface.
Difficulty: Middle school
The effect of nitrate levels in water on the growth of plantsFeatured science projectScience project video
This science fair project was conducted to ascertain the effect of water nitrate levels on plant growth. This will help us better understand how to use fertilizers to help plants grow better.
Difficulty: High school
What are the effects of urbanization on inshore plankton?
This lab activity in counting plankton, reinforces the use of the microscope. Differences encountered in count may lead to an exercise in graphing the observed results and stimulate discussion concerning plankton count variation from selected collection sites.
Difficulty: High school
How does acid rain affect our environment?
Demonstrate phenomenologically the effects of acid rain on our environment and perform long-term "real-time" experiments.
Difficulty: Elementary school
How to effectively keep our water supplies clean through filtration.
Students will see the techniques that are used to filter our water. Students will gain an idea as to various pollutants which can contaminate our water and an appreciation of the need to keep our water supplies clean.
Difficulty: Middle school
What is the effect of water pollution on wildlife and human habitats?
There are a wide variety of pollutants that can affect water and the plants and animals that live in the water. This pollution can be divided into three groups: chemical pollution, thermal pollution, and ecological pollution. Since not all pollution is human produced students need to understand that there are sometimes "natural" reasons for some pollution.
Difficulty: Elementary school
Which method is the most effective for treating water for chemicals, heavy metals and bacteria?
The purpose of this experiment is to determine which method of water purification, filtration, distillation, or solar pasteurization, is most efficient by treating tap and river water for pH, chlorine, total hardness, nitrate, phosphate, ammonia nitrogen, copper, and iron. These processes will also be tested to determine their effectiveness of removing E. coli B that has been previously introduced
