Hey, There's Corn in My Candy!

Science Fair Project Idea

Scientific Method

If you browse through a candy cookbook, you might notice that many of the recipes call for corn syrup in addition to sugar. Both sugar and corn syrup are sweet, so why do you need corn syrup if you already have sugar? In candy making, corn syrup is known as an interfering agent. But what does this mean and how does it work? You can find out for yourself by making two batches of rock candy, one with corn syrup and one without. For example, you could alter the science project When Science is… Read more

How Do Plants Change the Buildup of Greenhouse Gases?

Science Fair Project Idea

Scientific Method

Global warming is how scientists describe the gradual warming of our global climate. Scientists think that the trend towards global warming can be attributed to the build up of greenhouse gases in the earth's atmosphere from industrialization. Another problem is deforestation, as we remove plants and trees from the environment to meet a high demand for lumber or by clear cutting fields for farming and urbanization. By removing trees from the earth's environment, are we changing how greenhouse… Read more

How Does the Stem Grow?

Science Fair Project Idea

Scientific Method

Plant stems grow through a process of elongation due to cell divisions within the stem. Does the entire length of the stem elongate evenly? Or do certain regions along the plant stem grow more or less than others? Regions that are involved in active growth are called vegetative. You can conduct an experiment to show which regions of a bean seedling are involved in vegetative growth. Use a marker to mark one inch sections along the main stem of a young bean seedling. Number the regions 1-6… Read more

How Fast Can You Become a Virtual Rock Star?

Science Fair Project Idea

Scientific Method

Learning to play an instrument can be a lot of fun, especially when you can pretend to be a rock star as you learn! In this science fair project, you will study how your score in a music video game changes as you play and practice. You'll need a video game where you use a controller shaped like a musical instrument. Two examples include Guitar Hero and Rock Band, but there may be more! In these games, playing requires nothing more than a sense of the music's beat, and ridiculously fast fingers,… Read more

How High Can a Super Ball Bounce?

Lesson Plan Grade: Kindergarten-5th

Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity. Then they extrapolate to determine the height the ball would bounce if dropped from much higher heights.Engineering Connection Mechanical engineers select materials that meet… Read more

NGSS Performance Expectations:

3-PS2-2. Make observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion.

How Much Do Different Pet Species Eat Compared to Each Other?

Science Fair Project Idea

Scientific Method

Are you in charge of feeding your family pet? How much food do you think your pet eats compared to other kinds of pets? After adjusting for your pet's body weight, you might be surprised how it will compare to other kinds of pets. What type of pet do you think will eat the most for its body weight? Read more

Is It a Country Ballad? Listen to the Beat!

Science Fair Project Idea

Scientific Method

Have you ever noticed that hip-hop songs have a fast tempo, while country ballads are usually slow? Do you think there is a correlation between the number of beats per minute (bpm) in a song and the type of music? You can explore whether different genres of music have different bpm ranges by measuring the bpm in several different songs from a number of different genres. Bpm can be measured using free music software, like the one listed below in the Bibliography, or by counting all the beats you… Read more

"The Plane of the Ecliptic" © 2017 NASA Because of the different amounts of time it take for Mars and the Earth to each orbit the sun, it sometimes may look like Mars is traveling backwards. In this interactive lesson, students will learn what "retrograde" and "opposition" means in astronomy while modeling this phenomenon. Read more
