 | How does the pulse relate to the heartbeat and how does it differ when the body is in different positions? Take your pulse at mutiple sites. Relate the pulse to heartbeat. | ||
| |||
| Do boys and girls have different resting pulse rates?  The purpose of this experiment was to determine if gender in seventh graders affects resting pulse rate. | ||
| |||
 | Which Parent Affects Fingerprint Pattern Types More? The purpose of my project is to find out if the male parent or the female parent affects the offspring's fingerprints more. | ||

 | Can the Purple Loosestrife, a foreign plant be destroyed by introducing its natural enemies without damaging agricultural crops? Examine ways for the biological control, of a foreign plant, with its natural enemy without harming the native plants of North America. To determine if any stage in the beetle, Galerucella calmariensis and Galerwcella pusilla life cycle will feed only on purple loosestrife, Lathrum salicaria, or if it will feed on agricultural crops in North America. | ||

| Do changes in the environment such as temperature and light affect shrimp in their choice of habitats? In this lab, you will examine the habitat preferences of the brine shrimp, Artemia. You will use controlled experimentation to determine the thermal, pH, and light environments selected by Artemia. Based on your experience with this lab, you will design an experiment that could be used to survey other variables and other organisms. | ||

| What are the best places on your body to meassure your pulse? 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 | ||
| |||
| Do groups of people have different blood pressure readings? 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 | ||
| |||
| Does caffeine raise a person's blood pressure? My hypothesis is that when caffeine is consumed in large amounts it will increase the blood pressure. | ||
| |||
| What is the effect of music beat on a kid's blood pressure? The purpose of this experiment was to determine how two different tempos of music would effect 6th grade boys' blood pressure. | ||
| |||
| Which method is the most effective for treating water for chemicals, heavy metals and bacteria? The purpose of this experiment is to determine which method of water purification, filtration, distillation, or solar pasteurization, is most efficient by treating tap and river water for pH, chlorine, total hardness, nitrate, phosphate, ammonia nitrogen, copper, and iron. These processes will also be tested to determine their effectiveness of removing E. coli B that has been previously introduced | ||

Science kits, science lessons, science toys, maths toys, hobby kits,
science games and books - these are some of many products that can
help give your kid an edge in their science fair projects, and develop
a tremendous interest in the study of science. When shopping for
a science kit or other supplies, make sure that you carefully review
the features and quality of the products. Compare prices by going
to several online stores. Read product reviews online or refer to
magazines.
