Does Weight Affect a Drone's Battery Life?

Science Fair Project Idea

Scientific Method

Drones—also called quadcopters or unmanned aerial vehicles (UAVs)—are an increasingly popular toy for hobbyists. Some companies even want to use them for business purposes, like delivering packages right to your doorstep! However, drones typically have a rather short battery life. Does the added weight of a package affect a drone's battery life? Try this project to find out! Read more

Does Your Mobile Phone Radiate? Measuring Cell Phone Electromagnetic Radiation

Science Fair Project Idea

Scientific Method

Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for more than just making calls though. They use them for texting and searching the Internet, too. But some health groups are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics science project, you will investigate how much radiation your cell phone emits when used… Read more

Dog Scents: The Super Nose of Man's Best Friend

Science Fair Project Idea

Scientific Method

Everyone thinks their dog's the best, but in the case of smelling ability, all dogs possess super powers. In fact, a dog's nose can be over a 1,000 times more sensitive than a human's! In this project, learn about smell from a dog's unique perspective. There will be a whole lot of sniffing going on when you set up these fun experiments to find out what scents your dog and other canine friends find most interesting or appealing. Read more

Dog Toys: What Makes One a Favorite or a Flop to Fido?

Science Fair Project Idea

Scientific Method

Got a pampered pooch in your household? Then you know how much most dogs love their toys. And not just any toy. It has to be that particular beat up ball, gnawed frisbee, or ratty not-so-plush-anymore bunny with only one eye and partial ear remaining. Seems that dogs, like people, have definite preferences for their play things. This fun project investigates what makes a toy interesting to a dog. In these experiments, you and your dog can have some fun while you learn about canine behavior… Read more

Don't Get Burned! Measure the UV Index at Different Times of the Day

Science Fair Project Idea

Scientific Method

It's true that the light from the Sun provides the heat and light we need to survive here on Earth, but it also poses a threat. Ultraviolet (UV) rays in sunlight cause damage that can lead to early skin aging and even skin cancer. In this science fair project, find out when you need the most protection from UV rays by using a personal UV monitor to measure how the level of ultraviolet light changes during different parts of the day.

Don't Stand So Close To Me! An Investigation into Personal Space

Science Fair Project Idea

Scientific Method

How do you feel when a friend comes too close to you? How far away or close do you think is necessary to have a conversation with someone? The answers to these questions are dependent upon the size of your personal space. Some people like to be within a foot of each other when having a conversation and others feel that being 3 feet apart is still just a little too close for comfort. Personal space is defined as the protective area surrounding a person's body (not necessarily spherical in… Read more

Do-Re-Mi with Straws

Science Fair Project Idea

Scientific Method

Do you love to make music, but do not have access to all the instruments you would love to play? Check out this fun science fair project about the physics of musical sound production. You will make musical instruments with drinking straws, one for each note on a one-octave major scale. Can you figure out the right lengths for a series of straw "oboes" in order to play a musical scale? Read more

Drawing Circles Around Ants

Science Fair Project Idea

Scientific Method

Do ants sometimes ruin your picnic? There are some chemical ant repellents you can spray to keep them away, but who wants to spray poison all over their food? In this science project you can investigate some less toxic solutions that may be around your home so that your next picnic will not become an ant buffet! Read more

Drive a Race Car with Machine Learning

Science Fair Project Idea

Engineering Design Process

How do you design a program that can pilot a self-driving race car? By using machine learning. In this project, you will train your own machine learning model for an autonomous vehicle, the AWS (Amazon Web Services) DeepRacer. You can run your car's machine learning model on a simulated racetrack (Figure 1), or you can purchase a 1/18 scale model vehicle that can race on a physical track (Figure 2 - note: new cars are no longer for sale, but you may be able to purchase a used one on a site like… Read more

How do you steer a drone using a controller with a joystick? Find out in this activity as you program an Arduino to interface with an analog joystick, similar to those found in most video game controllers. You can use the joystick to make a mini popsicle stick drone tilt side to side or move up and down. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more
