This science fair project was done to determine which gender is more affected by the influence of peer pressure. The experiment was done by posing some simple questions to participants in a group setting.

Mariotte siphons or Mariotte bottles (figure 1) are devices that provide a constant pressure that will deliver a constant rate of flow from closed bottles or tanks. The flow rate will depend upon the head as defined in figure 1 and not on the height of the free water surface. These devices find many uses where a nonchanging pressure is needed. One application in agriculture is for applying liquid

The pulse represents the variation in blood pressure from diastole to systole. During diastole blood pressure falls, but increases after systole as the heart pumps more blood into the arteries. You feel this difference when taking your pulse. Doctors use a device called a sphygmomanometer

The purpose of this experiment is to find out which high energy foods, such as orange juice, affect the blood sugar levels in a person; the amount it affects them plus the time it affects them. The hypothesis of this experiment is that the blood sugar will rise to its highest level in an half hours time and back to normal by one full hours.

Blood pressure varies relative to heart's pumping of blood. The heart should be thought of as a dual pump, with a right and left side. Systole represents the active pumping of blood from the ventricles into the circulation. The right side of the heart takes venous/returning blood from the body and sends it to the lungs to be oxygenated (pulmonary circulation). Measuring blood pressures

My hypothesis is that when caffeine is consumed in large amounts it will increase the blood pressure.

The purpose of this experiment was to determine how two different tempos of music would effect 6th grade boys' blood pressure.

What are blood cells? What do they look like? What functions do they perform? How can I recognize the different categories? This is a short description of the blood cells and includes a simple experiment which allows you to become familiar with the cells of this precious liquid. The blood consists of a suspension of special cells in a liquid called plasma. In an adult man, the blood is about 1

Music has been proven scientifically to have beneficial effects, both mentally and physically. Music has been shown to reduce blood pressure, change our heart and respiration rates, relieve stress and muscle tension. How you ever wondered whether music also affects our short term memory? Many students prefer to study while listening to music, and maybe they should in fact do so, if doing so
of the population leaves the habitat for a new one. If the new habitat has different environmental pressures than the previous habitat, this population of butterflies will develop new adaptations in order to survive. For example, if the new habitat is barren and sandy, the butterfly may evolve a new wing color, that will help it blend in with its new environment. In this manner, a new species of butterfly evolves
