Science Fair Ideas on Popcorn Projects

Popcorn is one many peoples favorite snacks. Bringing it into the science fair is a great idea for a project. You can show off some ingenuity and bribe the judges with delicious treats! There are nearly an infinite number of experiments with popcorn. A few of them are listed below.

Please Remember popcorn is just heated corn. Handle with care right after cooking

Almost all popcorn experiments give us one of two things; a better taste, or more popcorn. Taste can be a matter of preference. Here are two experiments that get us more popcorn, faster.

1) Which Brand leaves the fewest unpopped kernels. Choose 3 different brands of popcorn. Count out 3 groups of 100 kernels for each brand, a total of 900 kernels. Pop them in batches of 100. Count how many kernels are left by each brand. Repeat this 3 times for each brand. Create a chart showing your results. You could also do a break down on the cost per popped kernel. Did the most expensive brand produce the most popcorn?

2) Which brand of popcorn pops the fastest No one wants to wait for their popcorn. Win the judges over by letting them know which brands of popcorn will get to them the fastest. Choose 3 different brands of popcorn. Count out 3 groups of 100 kernels for each brand, a total of 900 kernels. Pop them in batches of 100, timing them. (The popping will go on for a while once the cooking process is done. Determine a time frame between pops that qualifies as "done")

Now you know which brand pops up the fastest. Consider looking at what other variables affect the time. What happens if you freeze the kernels? How about if you refrigerate them? Does your elevation play a role.

Ten Things You Should Know About Pet Snakes

If you are one of the legions of people who have acquired, or are about to obtain a new pet snake, then you are also about to have a rewarding experience. Snakes have a lot to teach us. A properly maintained terrarium can be a work of art - many are prominently displayed in homes - so long as the snake keeper keeps some essential information in mind:

Be sure you give your snake enough heat - that means enough for the snake, not you. A snake is best kept at warmer, summer temperatures of 85 100 degrees F, unless being cooled for hibernation. Temperate zone species may tolerate a 30 degree drop in temperature at night, but tropical species rarely do well with such fluctuations.

Never, ever use your snake to scare somebody! Many people are afraid of snakes, some pathologically so. Using a snake to scare a person is irresponsible of you, may cause injury to another person, and is traumatic for the snake.

Be sure to feed your snake an adequate diet at appropriate intervals. Snakes under 3 feet in length should generally be fed prey about the size of an adult mouse once or twice a week. Larger snakes take more or larger prey at less frequent intervals. Truly large snakes may eat only once per year, but these are not snakes for novices.

Do not handle snakes after feeding, or until they have digested their meals. If a snake is handled too soon after eating, it is often likely to regurgitate the meal, and may refuse to feed for many days afterward.

Snakes must shed their skins, but they do much better if you do not help them. If the snake has been fed and watered well, it will grow, and the old skin is carefully broken by the snake and shed in one piece. If a snake sheds in patches, it may be dehydrated or have a nutritional disorder.

Do your homework! Buying a snake is not the same as knowing how to care for it properly. It is your responsibility to learn about your snake and any special needs it will have in captivity. For example, unless you carefully teach your snake otherwise, many have specialized diets: garter snakes eat fish and frogs, hognose snakes eat toads, and corn snakes eat small rodents and eggs.

Get a snake veterinarian lined up now. Snakes have a slower metabolism than us mammals, so they may manifest symptoms long after contracting an illness. Waiting to find a qualified vet until the snake is ill may be too late.

Clean the snake's cage as it becomes dirty - don't merely wait for Saturday morning. Only use appropriate disinfectants for a snake cage. You may use rubbing alcohol, soap, and specialty products available at your pet shop. Do not use chlorine bleaches or industrial cleansers such as Ajax or Comet, because their residues are often toxic to snakes. Lysol is particularly dangerous.

Always wash your hands well with soap and water after handling your snake or the cage accessories. Snakes, like most animals, may harbor dangerous bacteria such as Salmonella.

Okay, now go watch your snake and have some fun!

Dr. Sprackland started keeping snakes in 1960. There are still snakes in his life!

Biology Evolution - "Just A Myth"?

Biological evolution shows us how a creature can adapt and has adapted over time. If any particular species could not adapt (change, or evolve), it would become extinct quickly because the environment is changing all of the time. The changes in a species happen so that the species can have a better chance of survival. Many species have done so throughout the time of life's existence on earth. For instance, there is a species of moths that have developed ears that are especially sensitive to the sound frequencies in which bats use to hunt the moths. The moths have adapted to their environment by developing sonar abilities, like the bats. The moths were not equipped with this ability before adaptation occurred. This long process has made this particular moth species stronger and the chance of survival better. The adaptation does not happen overnight. It evolves over generations. Changes happen slowly.

Air Pollution/ Lung Adaptation

Our species cannot evolve fast enough to keep up with the ever-changing pollutants. It takes generations of changes in the genetic makeup of a population. Sometimes this may take billions of years. Air pollutants vary widely from city to city, state to state, and so on. The human species' lungs cannot evolve to detoxify each individual toxin if each environment is different. People are exposed to different toxins and pollutants depending on where they live (their habitat). The species would have to evolve as a whole. Evolution does not occur in a single individual alone, but in a complete species. If the human species were able to adapt quickly, there is a good possibility that cancer would be eradicated from our species. The flu virus adapts; changing to become immune to vaccinations. The virus becomes stronger as the human race tries to prevent just that. However, the human species is a more complex system than that of the flu virus.. Being a simple organism, the flu virus has only minute changes to make in order to adapt differently to the vaccinations' makeup. There is no possible way, therefore, for the human body to adapt and be able to detoxify air pollution. These changes would simply take too long.
