Three Fast and Easy Science Projects: Fun Ideas for Last Minute Projects

Age and Music Volume

Do your parents always complain that your music is on too loud, when you think that the volume level is perfect? This fast and easy science project will help you figure out whether it’s just a difference of opinion, or whether you can blame it on their ages.

Find a CD player or MP3 player where the volume is adjusted digitally and there are small gradations between each volume level. Then have ten or fifteen people below the age of twenty listen to music using the player, and note the volume level that they choose. Make sure to write down each piece of data! Then repeat this process with an equal number of people above the age of forty. (For a slightly more involved process, you can make three age ranges – 10-20, 30-50, and 70-90.)

Calculate the average volume preferred by the younger group by adding up all of their volumes and dividing by the number of younger people in your study. Then do the same thing to find the average volume preferred by the older group. Voila! Your experiment will show whether age affects the volume of music that people feel most comfortable with.

Do Lie Detectors Work?

Lie detectors measure many responses in a person’s body to see whether they’re lying. One of these is the person’s pulse. This is based on the assumption that when people lie, their pulse rate will get higher. You can design an experiment to see if this assumption is true by checking a person’s pulse before lying and after lying. Does the rate increase? Try this several times on numerous people and draw your conclusions about the effectiveness of this aspect of lie detectors.

Color of Print

Does the color of a text affect a person’s reading comprehension? You can test this by printing out the same passage in several different colors, such as black, blue, and yellow. Give each subject a copy of the passage in a different color, and ask them the same questions about the passage. Record the amount of time that it takes for them to correctly answer each question. Then find out whether the average time that it took to answer the questions using one color of text is more or less than the average time it took to answer the questions using another color of text. There’s your conclusion!

These fast and easy science projects are the perfect way to bring home a ribbon at a science fair or ace a science class – with very little time and effort spent!
