At advanced levels, scientists test every possible difference in products.
Product testing science projects test the difference of various types of products. However, you want to avoid science fair projects that involve testing for preferences, according to Science Buddies. Do not do projects on which paper towel cleans better. Instead, focus your project on testing the scientific differences in products. Whenever performing a scientific test, remember to ensure that no other factors than the one you test for affect the outcome of the project.
Take six or seven different types of lampshades (square, pyramidal, black, white and colored, to name a few), and measure the shape of the lighting for each type. Using a marked “X” on the floor, cover the floor and walls with art paper rolls. Then trace the different arcs and lines created by the light coming from around the lamp shade. Use a light meter to measure the amount of light at 20 different points (using the same points for each lampshade). Take a picture of each lampshade for your presentation folder or board. Plot the information on how much light came from each lampshade and the distance of the light. After you plot the information into a graph, determine which lampshades require the use of more energy because they do not spread or shape the light appropriately for a room. A more advanced project could look at the height of the lamp fixture and its resulting use of energy.
Candles do not just add romance; they also provide light in emergency situations. For this product testing study, test the wind and water resistance of several different types and shapes of candles, including pillar, seven-day candles, taper, gel, votive and tea-light candles. Cover a table with fireproof material, and mark an “X” with tape in the center of the material. Place three “X” marks on the floor using tape. Place a candle on the “X” on the table and a non-oscillating fan on the farthest (from the table) “X” mark on the floor. Light the candle. At the same time, turn on your fan and a stopwatch. Time how long it takes the candle to extinguish. If the candle does not extinguish after two minutes of the fan, mark “non-extinguishable” in your records. Repeat the experiment several times for each type of candle. Plot the average time it took for the candle to extinguish on a graph, and use the information to determine which type of candle provides the most wind resistance.
For this type of project, you test the relationship between colors and the perception of time. Although this does not test a specific product, you can apply the information to room decorations, paint colors in offices and more. For this project, you need to take a chair and place it in front of a wall in a white room. Ask at least 20 of your classmates to participate. Place a large piece of colored fabric on the wall so that the majority of the person’s viewing plane includes that color. From the moment the person sits down and begins staring at the fabric, start a 20-minute timer. Do not tell the person how long she sat in the chair. At the end of the 20 minutes, ask the person how long she felt that she sat in the chair. At the end of the study, look for discrepancies in perceived time versus real time.
With the information from this study, you can determine what paints interior designers should choose for different activities, if businesses can use colored lighting to prevent workplace boredom or even how industries can influence customer perceptions using room colors.
