Science Fair Project Idea

Scientific Method

You've heard of gold mining and coal mining, but think outside the box...or the planet...what about asteroid mining? Scientists, engineers, and business people believe asteroid mining is feasible, and they are in the beginning stages of long-term plans to mine asteroids for valuable resources during space missions. You don't want to miss out on all the fun; in this science project, you will come up with your own scientific plan for an asteroid mining company. We will help get you started by… Read more

As more people start living and working in space, we have to design our crew capsules and space habitats to keep people comfortable. That doesn’t just mean comfy beds and space sweatpants but also includes what our work environments and new homes will sound like on the inside. First, astronauts have to get to space using rockets, which generate a large amount of noise inside the crew capsule. Once they’re in space, astronauts are busy tending to many tasks. They perform daily tasks including… Read more

Balancing Act: Finding Your Center of Gravity

Science Fair Project Idea

Scientific Method

Like to have the balance of a tightrope walker? Try the more close–to–the–ground balancing test in this easy experiment to learn a few trade secrets of the high wire experts. In this project, you'll find your center of gravity and explore the physics of balance at the same time. No net required for this balancing act! Read more

Baseball Bat Debate: What's Better, Wood or Aluminum?

Science Fair Project Idea

Scientific Method

So baseball's your game? Well, slugger, science and math abound in baseball. Just look at the zillions of "stats." In this project, you can produce some interesting baseball statistics of your own and perhaps settle a long-standing debate. You'll set up experiments at your local playing field to find out which type of bat is better, wood or aluminum. Play ball, and batter up! Read more

Do your students ever wish they could block out an annoying noise or music they don't like? In this fun lesson plan, they will design sound-insulating containers and measure how well they work using a mobile phone and a sensor app. Read more

NGSS Performance Expectations:

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Blowing Bottle Tops: Making Music with Bottles

Science Fair Project Idea

Scientific Method

Have you ever blown across a bottle's top and made a pleasant, resonant sound? If so, have you wondered how that note is made exactly? A bottle is actually what is called an air cavity, also known as a Helmholtz resonator. Ocarinas are examples of musical instruments of this type. In this science project, you will use bottles to investigate how the volume of air in the cavity affects the pitch of the note that it makes. All you need are some bottles, water, a ruler, and a chromatic tuner. Read more

If you live in an urban area, you probably hear them almost every day: sirens. Police cars, ambulances, fire trucks—they all can come blaring. Their wailing sounds are piercingly loud to help alert others to clear the road in front of them. But have you ever thought about how this loud noise is generated? Make your own disk siren in this activity and find out for yourself. Read more

Build a Fuzzy Companion Robot

Science Fair Project Idea

Engineering Design Process

Snuggling a dog or cat can make you feel better even when you are not lonely or sick. Therapy and companion animals are also used for patients in health care settings, but sometimes you cannot always have access to a real live animal. Can a robot serve the same purpose? Find out in this project when you add an Arduino to a stuffed animal to build a purring companion robot. Read more

What would your students do if your town's water supply was cut off due to an equipment failure or natural disaster? Inspired by Global Problem Solvers: The Series, in this lesson plan they will tackle a real-world engineering challenge by building a prototype of a device that can manually pump water during an emergency. They will also think like entrepreneurs and come up with a business plan for how their device could be produced, sold, and used in the real world. This lesson is one of… Read more

NGSS Performance Expectations:

3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
MS-ETS1-1. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Build an Electronic Piano with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Lights and music make a great combination! Getting sound and lights to complement each other just right helps set the mood for everything from DJ parties and concerts, to theater shows, the circus, and ballet performances. You can put together your own lights and music show using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. Once you have the basics down, you can keep tinkering with the circuit, the sounds, and the program to make fancier versions… Read more
