How much does a typical student know about endangered species?
We would like to do a survey research project on student knowledge about endangered and extinct animals. Our hypothesis states that the majority of the responses to the factual questions on the questionnaire will be correct.

How to build a homemade magnetometer to study how the earth's magnetic fields are affected by solar storms
Solar storms can affect the Earth's magnetic field causing small changes in its direction at the surface which are called 'magnetic storms'. A magnetometer operates like a sensitive compass and senses these slight changes. The soda bottle magnetometer is a simple device that can be built for under $5.00 which will let students monitor these changes in the magnetic field that occur inside the class

How to make your own comet
In ancient times, people did not understand the objects in the sky, how they moved or what they were. They did not know what a comet was, where it came from, or where it went. A large comet is a spectacular sight and inspired both awe and fear in primitive peoples.

How to calculate the distance of the sun and the moon from earth, by understanding eclipses
Hipparchus, who used an eclipse of the Moon to deduce the precession of the equinoxes (here), used a total eclipse of the Sun--probably in 129 BC--to estimate how far the Moon was. That distance had also been derived from a lunar eclipse by Aristachus--see here.

What sort of fabric would best keep an astronaut warm?
My hypothesis is that spacesuit prototype #3 will be the prototype that will conserve more heat than prototypes #1 and #2. Prototype #3 has 6 layers. It has foam, fleece, and camouflage for warmth. #2 has 5 layers. It has foam and camouflage for warmth. #1 has 7 layers. It has fleece, Aluminized Mylar, and camouflage for warmth.

How to build a sidereal pointer to help us to locate the position of a celestial body
In this article, we talk about the construction of a sidereal pointer. It is an instrument that allows you to localize each celestial object in the night sky, just knowing its coordinates.

Understanding and identifying black holes
Physicists have predicted that at the Big Bang, black holes with sizes from 10^-5 grams up to perhaps solar mass size might have been formed. Use the above formulae to predict the mass range of the black holes would have lasted as long as the present age of the universe, between 9 billion to 15 billion years, and which should just now be evaporating completely away. Predict what the final few thou

Is it possible to collect micrometeorites from the outdoors?
Collect micrometeorites from indoor and outdoor sources.

Describe how fog forms
It's easy to simulate the formation of radiation fog. All you need are two bottles with a narrow enough neck that you can stick an ice cube into the mouth.

Why is the sky blue?
The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.
