Science Fair Project Idea

Scientific Method

Digital cameras can be a great way to learn about photography. Most digital cameras today have LCD screens, so you get instant feedback on your photo. If you make a mistake, no problem, you just delete the picture. It's nice that you don't have to worry about the expense and bother of developing film! This project can help you learn to take better pictures. Read more

Digital Voice Analysis

Science Fair Project Idea

Scientific Method

Use sound recording and analysis software to record voices of your family members. Can you figure out ways to identify each family member by just looking at the analyzed sound patterns from their voice (e.g., spectral frequency analysis)? Develop a hypothesis about what types of sound analysis will identify an individual. Have a helper record additional test files of your family members, without telling you which file belongs to whom. Unplug your computer speakers and see if you can… Read more

Ding, Dong, Ding, Dong: Morning Bells Are Ringing

Science Fair Project Idea

Scientific Method

For centuries, beautiful bell towers, like the Leaning Tower of Pisa, have been the center of village life, announcing the time of day, the joy of weddings, and the sorrow of funerals. They were also used to call villagers to action in times of danger. Have you ever wondered, though, why people put the bells in towers? The bells are so heavy, why haul them all the way up to the top of tall towers? Why not just ring them on the ground? Putting bells up high does make for a dramatic visual… Read more

Discovering Rainforest Locations

Lesson Plan Grade: 4th-8th

"Global Biomes" © 2012 NASA Socioeconomic Data and Applications Center In this activity, students will compare maps showing worldwide temperature, precipitation, biodiversity, and soil nutrition levels to predict where on our planet rainforests are located. Read more

NGSS Performance Expectations:

4-ESS2-2. Analyze and interpret data from maps to describe patterns of Earth's features.
5-ESS2-1. Develop a model using an example to describe ways in which the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
MS-ESS2-6. Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.

Disinfectants

Science Fair Project Idea

Scientific Method

Disinfectants are products that kill harmful bacteria that inhabit surfaces. Disinfectants can be in household and personal cleaning products. Which products work best? Compare different household cleaning products, like bleach or Lysol, to see which ones kill the most bacteria. Compare different brands of antibacterial hand soap or dish soap to see which brand is the most effective. How do hand sanitizers work? Compare rub-on hand sanitizers to see if they work better than alcohol, or compare… Read more

Distracted Driver: Do Distractions Affect Driving Video Game Scores?

Science Fair Project Idea

Scientific Method

Have you ever tried rubbing your stomach and patting your head at the same time? What about doing your homework or studying for your math test while watching television? It is tough to focus on a task when you are distracted doing something else, isn't it? In this science fair project, you will investigate how distractions affect your focus on a task, such as driving, by looking at how gaming scores are affected as you're talking on a cell phone or having a conversation with a friend.

Divide and Conquer: Proving Pick's Theorem for Lattice Polygons

Science Fair Project Idea

Scientific Method

If you like to play Tetris, then you might like this project. You will learn something interesting about the mathematics of complex shapes as you try to prove Pick's Theorem. The strange shape below is an example of a lattice polygon, which is a polygon whose vertices lie on points in the plane that have integer coordinates. As you can see, it is a complex shape, but there is an easy way to calculate its area, by simply counting lattice points! If you count the number of lattice points on… Read more

To slow the spread of COVID-19, the CDC recommends wearing a mask or cloth face covering—particularly in places where it is impossible to maintain social distancing (staying at least 6 feet away from others). This recommendation is for everyone age two or older (children under the age of two should not wear masks). Many instructions to make your own mask are available online. This activity will help you think through the process of designing and making a mask as an engineering problem.… Read more
