Helmholtz Resonance and Musical Instruments

Science Fair Project Idea

Scientific Method

Helmholtz resonance, or air cavity resonance, refers to the resonance of air in a container with a small opening, like a plastic bottle or the devices shown in Figure 1. The resonant frequency of the air depends on the volume of the air in the container and the geometry of the opening (its length and cross-sectional area). The Helmholtz frequency is not the same as the natural frequency of an air column in a cylinder, where the opening is the same size and shape as the rest of the cylinder. … Read more

How Do You Know Where You Are Without GPS? Dead Reckoning and Inertial Navigation

Science Fair Project Idea

Engineering Design Process

Put a meter stick on the ground. Starting at one end of the stick, close your eyes and try to walk exactly one meter. Open your eyes. How close were you? Now try it again with five, ten, or twenty meters. Does it get harder as the distance gets bigger? Without an outside reference from your visual system, it's quite difficult to know exactly how far you've gone! Electronic navigation systems face the same problem. Without an external reference like the global positioning system (GPS), it's very… Read more

What happens in our bodies when we get sick? How do vaccines protect us from certain diseases? These are some questions that students will learn to answer in this lesson plan. Through a series of activities, students will be introduced to our immune system. They will learn how vaccines make use of our adaptive immune response to fight diseases. Read more

Investigate Native Plant Evolution with Chloroplast Sequencing

Science Fair Project Idea

Scientific Method

Native plants are important for both ecological and medicinal reasons. However, most native plants are not very well studied. One way to know more about these plants is to understand which other species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a native plant and use this information to determine its evolutionary relationship to other species of plants. If the plant you chose has not been sequenced before, you can… Read more

Keep Your Arduino Robot From Falling Off a Cliff

Science Fair Project Idea

Engineering Design Process

Humans cannot see infrared light, but robots can! At least, they can when they use special infrared light sensors. These sensors can help robots detect nearby objects to avoid collisions and even help them avoid driving off edges. In this project you will build your own Arduino robot that uses infrared sensors to avoid driving off the edge of a table. Read more

Lichenometry: An Accessible Method for Dating Recent History (Geological and Manmade)

Science Fair Project Idea

Scientific Method

Have you ever noticed an old stone wall and wondered how long it has been there? If there is lichen growing on the wall, the lichen has most likely been living there since the time the wall was made, so if you could figure out how old the lichen is then you could deduce the age of the wall. Geologies use this method, called lichenometry, and other methods to establish dates and temporal sequences as they seek to construct a history from the available evidence. In this geology science project,… Read more

Locating an Earthquake Using a Global Seismic Network

Science Fair Project Idea

Scientific Method

When an earthquake happens, how are scientists able to determine the original location of the quake? In this project, you'll use archived data from a global network of seismometers to find out for yourself. You will make your own seismograms using the Global Earthquake Explorer program, and then use the seismograms to determine the location of earthquake epicenters. Read more

Magnetic Fluids

Lesson Plan Grade: 9th-12th

In this fun, engaging activity, students are introduced to a unique type of fluid "ferrofluids" whose shape can be influenced by magnetic fields! Students act as materials engineers and create their own ferrofluids. They are challenged to make magnetic ink out of ferrofluids and test their creations to see if they work. Concurrently, they learn more about magnetism, surfactants and nanotechnology. As they observe fluid properties as a standalone-fluid and under an imposed… Read more

Are your students passionate about the environment? Do they like to explore new ideas for more eco-friendly products? This lesson will give your students a chance to grow a product out of mycelium composite, a material that recently gained traction as an eco-friendly alternative for many plastics and foams. Students will analyze the impact of this product on the environment at every step of its life cycle, from raw material to the end of its life, and compare it to a plastic or cardboard… Read more

HS-ESS3-4. Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

Mars Terrain Exploration: A Hands-On Coding Investigation

Science Fair Project Idea

Scientific Method

Have you ever wondered what the surface of Mars is really like close up? Are you wondering what the Mars rovers get to see and experience? Some parts of Mars look smooth and sandy, whereas others are covered in rocks and rough terrain. In this project, you’ll step into the role of a planetary scientist and use real Mars rover images and Python code to detect, measure, and compare rocks across different types of Martian terrain. Here you’ll explore how image processing can help… Read more
