|  | Measure the kinetic parameters of invertase. Sucrose, commonly known as table sugar, is a disaccharide composed of an alpha-D-glucose molecule and a beta-D-fructose molecule linked by an alpha-1,4-glycosidic bond. When this bond is cleaved in a hydrolysis reaction, an equimolar mixture of glucose and fructose is generated. This mixture of monosaccharides is called invert sugar, which is derived from the fact that sucrose rotates plane polari | ||

| Can DNA be separated from other Cell components and Survive?  The purpose of this experiment was to see, by extracting DNA from an onion; if DNA could survive separated from other cell components. I became interested in this idea while I was watching "DNA: The Life Cell" on "The Discovery Channel"
The information gained from this experiment will benefit society by seeing if DNA will be safe separated from the other cell components. | ||

| Generational effects of acid rain on Drosophila melanogaster The purpose of this experiment was to test the effects of acid rain on several generations of living organisms. This researcher was interested in exploring whether mutations, found in an acid environment would also be observed if the offspring were removed from the acid environment into a neutral environment. Drosophila melanogaster were selected as subjects, due to their short life span, ease | ||

| The effect of calcium on hatching brine shrimp  This science fair project was performed to find out the effect of water calcium content, on the hatching of brine shrimp eggs. The science project experiment was done using water with different calcium concentrations of 0.1mg/100ml, 0.2mg/100ml and 0.3mg/100ml. | ||

| Do cell sizes differ, depending on the size of the organism? The researchers hypothesized that larger organisms are not necessarily composed of larger cells than smaller organisms. This hypothesis was based on the premise that many organism are composed of specialized cells that perform different functions and those cells may vary in size. The examination of four cell specimens from organisms of varied sizes supported the researchers' hypothesis. The four c | ||

 | How does acid rain affect seed germination? The purpose of this experiment was to determine the effect of acid on seed germination. I became interested in this idea because I know that acid rain is becoming a factor in pollution around the world. I know this from books I've studied and news articles Iíve read

| What is the effect of gibberellic acid on plant growth? The following lesson can be used as a way of approaching the scientific method during or after a unit on plant growth and development. This investigative activity will enable students to explore the effects of specific plant hormones (abscisic acid and gibberellic acid) on seed germination. They will formulate a hypothesis as well as design and perform the experiment to test the hypothesis. | ||

| What are bioassays and how effective are lettuce seeds as bioassays? 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 | ||

| 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. | ||

| Observing blood cells 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/ | ||

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.
