How to Do Successful Science Fair Projects
Easy Science Projects
Identifying Liquids in which Seeds Grow Best
Experiment: Pour 6-8 ounces of each of the following liquids into 6 plastic cups: plain water, orange juice, sugared water, vinegar, milk and water with a small amount of dissolved plant fertilizer.
Label each of the plastic cups to describe its contents.
Insert 4-6 bean seeds into each cup.
Observe the seeds daily and record the first day that individual seeds break their shells; also, record the size of each individual plant after regular time intervals. Record the average number of days for the seeds to break their shells for each liquid.
The Moldy Bread Project
Experiment: Print or type the word,“SALT” on the label of a sealable bag; sprinkle salt on a slice of bread; insert the bread into the bag and seal.
Print or type the words, “No Salt/Light/Dry/Room Temp.” on the label of another sealable bag and insert a slice of bread into the bag and seal.
Print or type the words, “No Light” on the label of another sealable bag; insert a slice of bread into the bag and seal: place the sealable bag into a paper bag.
Print or type the word, “Humid” on the label of a fourth bag; insert a dampened cloth and a slice of bread into the bag and seal.
Print or type the word, “Cold” on the label of a fifth sealable bag; insert a slice of bread into the bag and seal; and place the bag into the refrigerator.
Inspect each slice of bread after 5, 10, 15, 20, and 25 days and note the percent coverage for each. For addition information about this experiment, visit: Moldy Bread Experiment.
Identifying Which One of Five Materials Insulates Best
Experiment: Pour 6 ounces of water into an 8-ounce Styrofoam cup, an 8-ounce glass cup, an 8-ounce plastic cup, an 8-ounce metal cup and an 8-ounce ceramic cup.
Label each of the cups to describe the insulating material.
Place a thermometer into each of the 5 cups.
Observe and record the initial temperatures (They should all be apprpximately equal.)
Observe and record temperatures in one-hour intervals.Identify the cup and material that lost heat the slowest (best insulator) and the fastest (worst insulator).
Experiment: In a well-ventilated area, pour a small amount of ammonia onto 20-25 copper pennies, making certain that each is wetted by the ammonia. (A green coating will appear on each of the pennies.)
Pour 1 cup of white vinegar into a glass jar and stir in one-half teaspoon of salt until the salt completely dissolves.
Drop the 25 copper pennies into the jar of vinegar and wait until the green coating on the pennies disappears.
Drop an iron nail into the jar, after the nail has been thoroughly cleaned with steel wool.
After 8 to 12 hours, the nail will have a copper coating which is the copper plating.
