Harmful Algal Blooms in the Chesapeake Bay

Science Fair Project Idea

Scientific Method

Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to use archived data from continuous monitoring stations on the Chesapeake Bay to study how water quality measurements (dissolved oxygen (DO), salinity, temperature, pH, turbidity, and total chlorophyll) change before, during, and after harmful algal blooms.

The Tree of Life – II (advanced)

Science Fair Project Idea

Scientific Method

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use Web-based computer… Read more

How Do Baseball Stadium Dimensions Affect Batting Statistics?

Science Fair Project Idea

Scientific Method

Have you ever wondered how playing in a certain stadium affects how well the athletes perform? Major League Baseball (MLB) is played in ballparks that have their own individual quirks when it comes to the exact layout of the field. How an individual ballpark affects player performance, which is known as ballpark effects, is heavily investigated in the field of baseball. To name just a few parks and their different traits, Fenway Park (the long-time home ballpark for the Boston Red Sox in… Read more

Measuring the Diameter of the Earth's Core with Seismic Waves Around the Globe

Science Fair Project Idea

Scientific Method

When an earthquake occurs, seismic shock waves travel out through the earth from the source of the event. The shock waves travel through the earth or along the Earth's surface, and can be recorded at remote monitoring stations. Some of the waves that travel through the earth are blocked or refracted by the Earth's liquid core, which means that monitoring stations located certain distances from the earthquake do not detect these waves. This creates a "seismic shadow" that you can use to… Read more

Ecological Footprint Analysis

Science Fair Project Idea

Scientific Method

The sustainability of our planet's resources ultimately depends upon our actions as citizens. How much we drive, what we eat, whether we have pets, and whether we recycle are all individual actions that affect the sustainability of the Earth's resources. Learn how ecological footprinting works and figure out how big your footprint is. How big is your family's footprint? Your school? A local business? Can you propose ways to increase or decrease the size of your ecological footprint? Develop… Read more

Expression Cloning

Science Fair Project Idea

Scientific Method

What is expression cloning and how is it used in the biotechnology industry? How are plasmids constructed for use in a bacterial expression system? You can investigate these questions and more using bacterial expression kits meant for high school classes. You will need a laboratory space equipped to grow bacteria and carry out simple molecular biology. A kit with plasmids and bacterial cells to transform are also needed. Here are two possibilities: BioBuilder What a Colorful World Kit … Read more

Build Your Own Helio Tracker—a Self-powered Mechanical Sunflower that Turns with the Sun

Science Fair Project Idea

Scientific Method

The amount of energy produced by most photovoltaic (solar) panels is limited, due to their immobility. However, when photovoltaic panels track the movement of the Sun, their efficiency increases significantly. This can be done with computers and sophisticated electronics, but for rural or wilderness settings, a "low-tech" sun tracker would be beneficial. A solution exists in nature: the sunflower. The challenge in this science fair project is to design and build a device that imitates the… Read more

Biowarfare: Experiment with Viruses that Destroy Bacteria

Science Fair Project Idea

Scientific Method

Most people are not aware that the soil around them is a battle scene. The combatants are very small—bacteria on one side and bacteriophage on the other. The bacteriophage (or phage for short) try to pierce the outer coats of the bacteria and inject them with phage DNA. If successful, the DNA will take over the inner machinery of the bacterial cells and force them to make many copies of the phage. After the copies are made, the bacterial cells break apart, releasing new phage that start… 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

Foldit: Playing a Game While Solving Protein Structures

Science Fair Project Idea

Scientific Method

Unlocking the three-dimensional structure of a protein is crucial to help scientists understand how it functions in our bodies and how it can cause devastating diseases if it becomes disrupted or interacts in the wrong way. However, figuring out the structure of a protein in three-dimensional space can be very challenging. Proteins are the functional units of our cells, and every protein is made up of a long chain of amino acids. Amino acids come in different shapes and sizes, and they have… Read more
