Light propagates, or travels, in waves. Waves have two main properties: frequency and wavelength. When you know one, it’s pretty easy to calculate the other.When light waves overlap they create interf ...
A pulley is a mechanical device that can be used to lift heavily objects more easily. Pulleys consist of a wheel that rotates on an axle—which is a rod through the center of the wheel—and a rope, cabl ...
The hype with the ShamWow is justifiable, as it is said that these ShamWows are made of a blend of rayon and polypropylene, which makes it super absorbent, but lightweight. Cotton is known for being v ...
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 ...
This project models a real world scenario and ecological issue: eutrophication, which results in bodies of water that are depleted of oxygen and are in a sense “dead”. The goal of the project is that ...
Bread is the “staple of life.” Most breads are made with yeast, which is a sturdy fungus that interacts with the grain and sugar to create carbon dioxide, which causes the bread dough to rise. The stu ...
Crickets chirp at regular intervals. The length of the interval depends upon the temperature. This project is not necessarily to demonstrate that this is true- it is- but to quantify exactly how accur ...

Electric energy is carried by current, which is the flow of electrons, which are the negatively charged sub-particles of atoms. This transfer of electrons from one place to another powers our lights, ...
Carbon dioxide is a greenhouse gas. Because carbon dioxide concentrations in the atmosphere have been increasing rapidly since the Industrial Revolution, the gas is of primary concern to the of globa ...
