I used this Flinn safety contract.
Acids, bases, and sea shells Seashells are the hard, outer coverings that mollusks produce, in order to protect themselves from predators; it also serves as a form of shelter form the elements.
Seashells come in a wide range of shapes, sizes, and colors; however, they all are created from the same material - calcium carbonate. In this science fair project, you will investigate how seashells, and other objects containing calci Difficulty: Can lettuce seeds be used as a bioassay medium for testing toxicity?
The idea behind a reference toxicity test is that the test organism, in this case lettuce seeds, will respond in a predictable manner to varying concentrations of a particular chemical compound.
At some threshold concentration, all of the test organisms will be killed or in this case, none of the lettuce seeds will sprout. In solutions that are more dilute, some level of inhibition will occur in Difficulty: High school 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 batterythe water is split into its two parts: 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. Middle school This experiment was performed to compare how quickly a scented and an unscented candle will burn.
The tests were done by comparing the length that the candles will burn in 30 minutes - using unscented, rose scented and apple scented candles.
Middle school Convection and salinity: How does salinity affect the movement of water? Convection is the phenomena characterized by the movement of molecules in gases and liquids. Heat causes molecules to be active, while cooler temperatures result in less activity.
Convection can be observed in volcanoes, in the ocean, in cooking, in heating your home and even in decorative lava lamps. In this science fair project you will observe how the addition of salt to water effects convecti Difficulty: This science fair project was conducted to find out the corrosiveness of different types of metals.
The science project experiment involved using copper, aluminum, iron and zinc plates. High school 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.
The atmosphere contains about. 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 Difficulty: Middle school Effect of temperature on glow sticks This science fair project was conducted to determine how temperature can affect the length of time a glow stick remains lit.
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.Chemistry is the study of molecules, atoms and materials – their composition, properties and reactions.
Chemistry holds a reputation of being one of the boring subjects, but it is not true since fireworks are based on chemistry.

SENIOR PROJECTS. During the senior year, chemistry students work collaboratively with faculty members on research projects as part of the Senior Program. chemistry investigatory project on the topic: to determine percentage of caffeine in different tea samples.
The Open Chemistry project is a collection of open source, cross platform libraries and applications for the exploration, analysis and generation of chemical data.
