How do magnetic field lines look like?
Iron filings align themselves in strong magnetic fields. This reveals the shape of the field patterns. A similar thing happens with the electric fields created by high voltage and by "static electricity." If small fibers are exposed to a very strong electric or magnetic field, they will align with the field and make it visible.
Dry Ice Experiments
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
Comparing the effectiveness of different disinfectants against bacteria
The purpose of this experiment was to determine which disinfectant would most effectively kill bacteria. The information gained from this experiment would help parents, health care providers, and food preparers to know which disinfectant to use to the best results for killing bacteria.
What effects would changes in the ozone layer have on Antarctica's penguin population?
The penguin population in Antarctica is diminishing. Scientific teams have already investigated predator-prey relationships, disease, and environmental pollution as possible causes. Data has been collected and analyzed. No correlation has been found between these factors and the penguins' decline. The International Symposium on Environmental Issues is meeting late next year in Sydney, Australia. E
Design a computer program to simulate the travel-path of billiard balls.
My objective was to determine how the initial angle of an idealized billiard ball path, starting from a corner of a rectangular table with integral dimensions, affects whether the path will eventually end in a corner. Based on some mathematical background research, I hypothesized that the path will terminate in a corner if and only if the tangent of its initial angle is rational.
Can neural networks identify decimal digits using visual basic and excel?
A neural network was designed and coded to identify decimal digits using Visual Basic and Excel. It was hypothesized that the neural network would have a 75% accuracy in recognizing the digits.
How to effectively keep our water supplies clean through filtration.
Students will see the techniques that are used to filter our water. Students will gain an idea as to various pollutants which can contaminate our water and an appreciation of the need to keep our water supplies clean.
Is it possible to collect micrometeorites from the outdoors?
Collect micrometeorites from indoor and outdoor sources.
Make your own PH indicator using vegetables
Red cabbage contains pigments call anthocyanins. The pigments give it the red/purplish color. Anthocyanins belong to group of chemical compounds called flavonoids. This experiment shows you how to make your own pH indicator using cabbage leaves.
What are the different methods of purifying water?
In this experiment, we examine different methods of purifying water including distillation, filtration and reverse osmosis
