Hurricanes

Science Fair Project Idea

Scientific Method

Unless you live in the Southern states, you only hear about the most destructive hurricanes. In fact hurricanes occur every year, even multiple times a year. Each hurricane is a tropical storm related to cyclones and tornadoes, some big and some small. Each hurricane is measured based upon several variables like: wind speed, diameter, direction of movement and speed of movement. Does the size of the hurricane correlate with the wind speed? What information can the eye of the hurricane… Read more

Investigate the Vitamin C Level in Bell Peppers During Various Stages of Ripeness

Science Fair Project Idea

Scientific Method

Vitamin C is a water-soluble vitamin that has many functions in the body. Vitamin C is needed to bolster the immune system. It is an antioxidant that protects LDL cholesterol from oxidative damage, and it is needed to make collagen, a substance that strengthens many parts of the body, such as muscles and blood vessels. Our bodies do not make vitamin C, so we must get it from dietary sources. Citrus fruits, carrots, avocados, and spinach all have vitamin C. Bell peppers, like the ones shown in… Read more
