Standard deviation is a statistic that tells you how closely a group of numbers (for example, temperatures) are clustered around a mean value (average temperature). When the standard deviation is smal ...
The project is about measuring the effectiveness of a detergent containing a UV-absorbing compound in blocking UV-A radiation.The goal is to have the student conduct a controlled experiment to test cl ...
Cold water is denser than warm water. Water with a high salt concentration (salinity) is denser than water that has a lower salt concentration. Warmwater rises above densercolder water, and bodies of ...
Most plastics are not readily biodegradeable, especially when buried in the ground away from sources of oxygen. Many can be decomposed partially by photodecomposition in the presence of sunlight, howe ...
Soil temperature varies from one month to the next depending upon such factors as solar radiation, rainfall, seasonal swings in overhead air temperature, plant cover, soil type, and depth in the earth ...
The project measures the growth rate of algae supplied with supplemental carbon dioxide.The goal is to have the student conduct a controlled experiment to test a hypothesis about conditions affecting ...
This project will look at how fabrics block UV radiation by examining how fabric thickness, tightness of weave, weight, type of fiber, and color influence the transmission of UV radiation. The goal is ...
Observe trends in the properties of writing over the period of 5000 years and extrapolate to a future time. The goal is develop a hypothesis that can be used to predict future trends in writing .It i ...
Amphibian populations are in global decline. Because the skin of amphibians like frogs, toads and salamanders is extremely sensitive to environmental changes, there has been much speculation that the ...
The project compares the ability of selected to block UV-A radiation. The goal is to have the student formulate, test and revise a hypothesis about the ability of optically transparent to block UV-A ...
