What natural insecticide is most effective against crickets?
The purpose of this experiment was to determine what natural pesticide is most effective in killing crickets. I became interested in this idea when I heard about the possibility of banning synthetic pesticides being banned from the market, due to safety issues.

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 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.

What makes stars twinkle?

What causes landslides?
A landslide inventory of the Touchet subbasin of the Walla Walla River Watershed was completed in 2002 by the WDNR. Using a combination of 1:24,000 scale orthophotos from 1996 and aerial photographs, nearly 250 possible landslides were located in the total 93 km2 (234 were accessed by road or trail; gates, road closures, or other obstacles prevented ground-truthing of the remaining 15 or so). The

What is soil erosion? Demonstrate how it happens
Erosion is the loss of soil from the land. It is a process that is always occuring but it can happen faster if we misuse the land.

What sort of blade design works best for windmills?
The purpose of this experiment was to determine which windmill blade sizes, shapes, and angles were most efficient at producing an electrical current from a generator.

Are carbon filters less effective when the water contains more chlorine?
