Skeleton Building

Science Fair Project Idea

Scientific Method

Do you like skeletons? One of the more interesting jobs at a natural history museum is the creation and care of the skeletons and bones. How do the curators clean and put together the skeletons? Many curators use the carrion beetle, Dermestes vulpinus, to quickly clean off the dead animal tissue from a corpse to reveal the skeleton. These insects do such a good job that sometimes the skeleton remains intact! Another method is to slow cook the carcass until the meat falls off. You can use… Read more

Skipping Science: An Experiment in Jump Rope Lengths

Science Fair Project Idea

Scientific Method

Did you know that the world record for the greatest number of jumps in a minute is more than 340? That's more than five jumps a second! How close do you think you can get to that number? If you are going to try to break the record, it might be important to figure out how jump rope length affects your success. Try your hand at this skipping science fair project and jump-start your chances for a jump rope record. If you have a smartphone available, you can use its accelerometer and a sensor app… Read more

Skunk Attack! Test Different Remedies to Remove Skunk Odor

Science Fair Project Idea

Scientific Method

Have you or one of your pets ever been sprayed by a skunk? Hopefully not, but if you have, you probably know that the smell can be very unpleasant and hard to get rid of. There are many "folk remedies" for getting rid of skunk scent, but if you ever do get sprayed by a skunk, how will you know which one to try? In this science project, you will test the ability of various mixtures to remove the bad scent from rags that have been contaminated with bottled skunk scent, and determine which one… Read more

Sleep Tracking: The Brain and Circadian Rhythm's Role in Sleep

Science Fair Project Idea

Scientific Method

Everybody sleeps, but not everybody has good quality sleep. Sleep is essential for the brain, but how do our daily choices impact sleep? In this science project, you will experiment and explore factors that influence your nighttime sleep schedule. Read more

Slinking Slinkies

Science Fair Project Idea

Scientific Method

Want to do a project with a toy your parents, or even grandparents, might have played with? Slinkies are fun toys that also make great physics and engineering projects. In this science project you will investigate how changing the angle of an inclined plane affects how the Slinky walks down it. What angle will enable the Slinky to go for the best walk? Read more

Slip Sliding Away: Experimenting with Friction

Science Fair Project Idea

Scientific Method

As you headed up the mountain to enjoy your last ski trip, you may have noticed a sign reading: Hazard! Icy Roads Ahead—Put On Your Chains. Putting chains on car tires increases the resistance between the tires and the road allowing the car to "grip" the road. This resistance to sliding is called friction. In this experiment, you will be investigating how to increase and decrease the friction between two surfaces. Read more

Have you ever tried to get a running start and slide across a smooth, wooden floor while wearing socks? What happens if you try the same thing on a carpeted floor, or while wearing shoes? The amount of friction between your feet and the floor surface determines how well you can slide. Some combinations of surfaces, like socks on a wooden floor, produce very little friction. Other combinations, like rubber soles on a wooden floor, produce much more friction. In this project you'll do a much… Read more

Smarter Farming with Aerial Photo Analysis

Science Fair Project Idea

Scientific Method

Wondering what sustainable, high-producing agriculture might look like? This science project explores how analyzing bird's-eye-view pictures of a field can make farmers aware of variations in their fields. Farmers can use this information to optimize their farming practices, or even feed this information to high-tech agricultural equipment so the machines can automatically adjust their actions (like fertilizing or watering) to the needs of a piece of land.

Sniffing Out the Science of Smell

Blog Post

These science projects help students explore smell-based questions related to human biology and food science. Sometimes, great science is right there at the tip of your nose. Like taste, how intensely or how accurately we smell things around us varies from person to person. You may even find that your sense of smell is stronger at certain times than others. Are you the first in your house to pick up the smell of a skunk in the area? Do you walk into… Read more

Soccer: Geometry of Goal-Scoring

Science Fair Project Idea

Scientific Method

Block off one-third of a soccer net with a cone, 5-gallon bucket or some other suitable object. Shoot into the smaller side from a set distance, but systematically varying the angle to the goal line. Take enough shots at each angle to get a reliable sample. How does success vary with angle? For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to… Read more
