Hurricanes and Climate

Science Fair Project Idea

Scientific Method

The past few years have histories of extremely powerful and dangerous storms. Storms have also become more numerous over the last few years. To investigate potential effects of climate on hurricane number and strength, in this project you will study the effects of El Niño on hurricanes. The goal of this project is to study the historic relationship between the El Niño/Southern Oscillation (ENSO) and the number and strength of hurricanes, either in the Atlantic or Pacific Oceans. Since… Read more

I See a Full Moon Rising...and Shrinking...or Do I?

Science Fair Project Idea

Scientific Method

Have you ever noticed how the moon appears bigger at the horizon, just as it is rising over the treetops, than it does later in the evening when it is overhead? Of course, the size of the moon does not change, but our perception of its size changes based on where it is in the sky. In this human biology science fair project, you will investigate Emmert's law, which explains the full moon illusion. You will estimate the size of the perceived increase in the size of the moon at the horizon. Read more

Identify Road Signs with Machine Learning

Science Fair Project Idea

Engineering Design Process

Driverless cars use machine learning, a type of artificial intelligence, to identify road signs and other things they encounter on the road, like pedestrians and other vehicles. In this project you will take your own pictures of different types of road signs and use machine learning to identify the signs using a free online tool (no programming is required). You will then attempt to improve your machine learning model so it can identify signs in a variety of environments. Read more

Incorporating Physics in Video Games

Science Fair Project Idea

Engineering Design Process

Have you ever played a video game and gotten so involved that you felt as if you were living inside the game? What were the characteristics of the game that made you feel part of the action? One component of an absorbing video game is an onscreen world that makes sense—a world that takes physics into account. A game in which the player feels the effect of trudging through mud, slipping on ice, or catapulting a bird is more fun than one with no environmental interaction. In this science… Read more

Interpreting Area Data from Maps vs. Graphs: An Experiment in Visual Perception

Science Fair Project Idea

Scientific Method

Graphical methods of data presentation are a key feature of scientific communication. This project asks the question, "What's the best way to compare the land area of states: a map or a bar graph?" You'll be measuring performance on two different visual discrimination tasks: comparison of areas vs. comparison of position on a common scale. Which method is more accurate? Which method is faster? This project will get you thinking about how to find the best way to communicate scientific… Read more

Invasive Species

Science Fair Project Idea

Scientific Method

Invasive species are organisms (either plant or animal) that have been introduced into a new, non-native area and spread rapidly in the new environment due to a lack of regulation by predators. Frequently, invasive species will out-compete native species for resources which can put native species at risk. This is an especially big problem for threatened habitat and endangered species, which are already at risk. Survey your area to document cases of invasive species invading a local… 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

Investigate the Kinetics of the Color Changing Iodine Clock Reaction

Science Fair Project Idea

Scientific Method

The iodine clock reaction is a favorite demonstration reaction in chemistry classes that usually requires toxic or hazardous chemicals. During the reaction, two clear liquids are mixed, resulting in another clear liquid. After some time, the solution suddenly turns dark blue. The reaction is called a clock reaction because the amount of time that elapses before the solution turns blue depends on the concentrations of the starting chemicals. In this green chemistry project, you will use a… Read more

Investigate the Vitamin C Level in Bell Peppers During Various Stages of Ripeness

Science Fair Project Idea

Scientific Method

Vitamin C is a water-soluble vitamin that has many functions in the body. Vitamin C is needed to bolster the immune system. It is an antioxidant that protects LDL cholesterol from oxidative damage, and it is needed to make collagen, a substance that strengthens many parts of the body, such as muscles and blood vessels. Our bodies do not make vitamin C, so we must get it from dietary sources. Citrus fruits, carrots, avocados, and spinach all have vitamin C. Bell peppers, like the ones shown in… Read more

Investigating the 'Mpemba Effect': Can Hot Water Freeze Faster than Cold Water?

Science Fair Project Idea

Scientific Method

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out as we expect! Read more
