This project requires the student to select at least three different brands of raisin cereal to see which one has the most raisins. The student gathers three sheets of paper towels and spreads them on a counter. He then pours the contents of each box onto a paper towel. The student picks out the raisins in each sample and places them in cups. He then counts the number of raisins from each brand of cereal. The experiment should be repeated three times with new boxes of the same brands.
The student chooses three brands of paper towels to test which is strongest. She tears off one sheet from each roll and places them on the counter. The student tests each paper towel brand by loading as many apples as possible on each sheet until the sheet breaks. She then records how many apples each brand held. The experiment will need to be repeated at least three times to ensure accuracy.
In this project, the student compares the shoe sizes of boys and girls of the same age. He records the shoe sizes of a group of boys and repeats the process for a group of girls. Once the data is collected, the student compares the range in shoe sizes and determines who has the biggest feet.
The student investigates the effect that milk has on the growth of a pea plant. She gathers four flower pots and places the same amount of soil and number of pea plant seeds in each pot. Then she selects three different concentrations of milk--skim, two-percent and full milk--and pours one of each in the same amount into the first three flower pots. Water is applied to the fourth flower pot. The student adds the same amount of milk and water to the plants daily for two weeks. The fourth flower pot will serve as the control plant to compare growth rate with the plants that were exposed to the different concentrations of milk.
