Have you ever wondered how ancient people could lift very heavy objects, such as large stones, to build pyramids? A lever is a simple machine that can help people do just this. It can also help make other kinds of physical work easier by giving the user a mechanical advantage. Common examples of levers you might see around you are seesaws, scissors, wheelbarrows and even the your own jaw. Although all of these levers have the same functional parts, they vary in where the different components… Read more

Golf Clubs, Loft Angle, and Distance

Science Fair Project Idea

Scientific Method

If your idea of a great weekend morning is taking some practice swings at a driving range, or heading out to the links to play a round, this could be a good project for you. This project is designed to answer the question, what is the relationship between club loft angle and the distance that the ball travels when struck. Read more

Have you ever tried making "walkie-talkies" using a long piece of string and two tin cans? If you have, you know that they work surprisingly well—at longer distances you can hear people better through the cans and string than you can through the air! In this activity we're going to use the same concepts to build a personal bell, one that makes sounds that only you can hear! Read more

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.

Harmful or Helpful? The Effects of Hydrogen Peroxide on the Roots of Plant Cuttings & on Seed Germination

Science Fair Project Idea

Scientific Method

Hydrogen peroxide (often used as a disinfectant) has also been approved for use in pesticides. This science fair project investigates whether hydrogen peroxide has any effects on seed germination or on roots of plant cuttings. Read more

Heart Rate Recovery Times

Science Fair Project Idea

Scientific Method

Over an average lifetime, the human heart beats more than 2.5 billion times, supplying blood to the entire body. When a person exercises, the heart has to work harder than usual. Have you ever wondered how quickly your heart beats when you exercise, or how long it takes to recover back to its normal rate after you are done exercising? Is the heart rate recovery time faster for people who get regular exercise compared to people who do not? Try out this science project to find out! Read more

Have you ever thought about where the vegetables you eat are coming from when it is too cold outside to grow them? They might have been shipped from a different country to your home town, or they may have been grown locally in a greenhouse. Greenhouses are huge house-like structures that are usually made mostly of glass. How can they protect plants from the cold? In this activity, you will find out and create some extra heat from the sun. Read more
