watering is so important to growing plants‚ changing the water that is given to plants can have an effect on a plants growth.

determine the effects acid and sugar in various amounts have on a cornstarch paste. The importance of this experiment is to examine what causes starch to thicken or thin which is relevant to obtaining the desired viscosity for recipes that involve starch cookery without complication. Factors to be considered in the thickening power of cornstarch include the concentration of starch‚ extent of gelatinization thus temperature and duration of heat‚ and the addition of sugar or salt (1).

On an 18th century British plantation there was constant battle between slaves and planters‚ for the slaves needed to keep their cultural forms alive.

wondered how much sugar it takes to overflow a mug in different water temperatures. I thought it would be cool to find out so i did an experiment. I used five diffferent temperatures of water 1.) cold tap water 2.) refrigirater water 3.)freezer water 4.) hot tap water and 5.) boiling water. I filled up a 2 cup mug with 1 3/4 cups of each type of water and added sugar until the mug overflowed. Purpose: I chose this experiment because I thought it would be fun to find out how much sugar was needed to

that when you eat too much sugar‚ your behavior changes. According the first article “Sweet Obsession; The Body Of Evidence Exonerates Sugar‚” “When kids eat a lot of sugar‚ they’re likely to develop nutritional deficiencies‚ and those in turn can cause a problem in their concentration and mental function” (Proulx‚ Lawrence G. 1995). This means that when kids eat sugar‚ their behavior and actions change to not normal. From this article‚ Proulx states that the so called sugar buzz doesn’t make you crazy
