Crystals are not alive, but they can grow. Growing crystals requires a little time and patience. If you have both (plus a few other ingredients), you can grow your own crystal gardens.
Difficulty: Middle school
The purpose of this experiment was to determine if temperature affects the mass of crystal growth. I became interested in this idea because I have my own crystal growing kit at home, and I would like to observe which temperature they grow largest in. The information gained from this experiment could aid scientists in growing larger crystals, as well as manufacturers who are interested in growing

Dry ice is frozen Carbon Dioxide, or CO2, which is a gas under standard temperature and pressure conditions. The atmosphere contains about .035% of this gas. CO2 is a greenhouse gas, which means it absorbs light at infrared wavelengths. An increase in the concentration of this gas would, some scientists believe, cause an increase in the atmosphere's average temperature. The high concentration of C

This science fair project was done to investigate the effect of increasing DC voltage and the concentration of electrolyte salt on the rate of production of hydrogen gas during the process of electrolysis.
Difficulty: High school
This science fair project was done to understand the importance of ammonia in the formation of salt crystals. Tests were done to compare the resultant formation of salt crystals when ammonia was not used, compared to when different amounts of ammonia were used.
Difficulty: Middle school
This science fair project was done to find out how the freezing point of water is affected by the presence of sugar or salt. The experiment was conducted using salt, sugar and water.
Difficulty: High school
This science fair project was conducted to determine how temperature can affect the length of time a glow stick remains lit. The experiment was done by placing a glow stick in water with a temperature of 5°C, 15°C, 25°C, 35°C and 45°C.
Difficulty: Middle school
This experiment was done to find out how temperature affects the solubility of various substances in water. The tests were done using salt, sugar and sodium bicarbonate at different temperatures.
