How the frequency at which a cricket chirps can be affected by external factors
There are several natural phenomena - the rate ants walk, the rate fireflies flash, the rate of a terrapin's heartbeat, and even the frequency of human alpha brain-wave patterns - that follow the Arrhenius equation closely. This page looks at one well-studied case, the chirp rate of the snowy tree cricket, oecanthus fultoni. This little cricket, shown below, is familiar to outdoor enthusiasts as a

Does music affect a child's ability to nap restfully?
The purpose of this experiment was to determine to what degree music affects the nap time behavior (restfulness) of preschool children in childcare.

Which brand of cooking spray works best?
wanted to find out how much food would stick to cookware using different brands of cooking spray. My hypothesis stated that name brand cooking spray would work the best, supermarket brands would be a close comparison, and that any amount of spray would work better than none at all.

Do white candles burn faster than colored candles?
My topic was about burning candles. I wanted to find out what color candle would burn the fastest. My hypothesis stated that, if I burned five candles, one red, one white, one yellow, one purple, and one blue, then the white one would burn the fastest.

How does the depth of the ocean affect its temperature?
Different parts of the ocean have different characteristics. The temperature of the ocean varies with the depth.

What are some characteristics of fat?
The fats people eat can come from either plants or animals. Fats from plants and animals are similar in some ways but different in others. In the activity below, you can do some simple experiments to learn some fat facts!

Is there such thing as a superior teaching method?
No single method of instruction is superior in every discipline or environment for every student. This survey of the literature covers a variety of instructional methods. Included are references to case studies comparing teaching strategies, reports of experiments that attempt to evaluate and assess the superiority of one method over another, historical reviews, comments on current issues, and pre

Can water be split into oxygen and hydrogen?
If an electrical current is passed through water between electrodes (the positive and minus poles of a battery), the water is split into its two parts: oxygen and hydrogen. This process is called electrolysis and is used in industry in many ways, such as making metals like aluminum. If one of the electrodes is a metal, it will become covered or plated with any metal in the solution.

Are carbon filters less effective when the water contains more chlorine?
The purpose of this experiment was to determine whether the efficiency of a carbon filter decreases faster at higher concentrations of chlorine.

How do phospates affect oxygen levels in water?
The purpose of this experiment is to test the effect of a phosphate on the oxygen levels in pond water. I believe that the phosphate will have an effect on the level of oxygen in the pond water. I think that the pond water with only ten drops of the phosphate mixture will have have more oxygen than the pond water with fifty drops of the phosphate mixture.
