You might have read about the negative impacts modern human civilization has had on the environment, like pollution, deforestation, and extinction of animal species. How can we use modern technology to help protect the environment? In this project-based lesson students will design an electronic circuit that can measure something in the environment like water quality and light pollution, and develop a plan for how their circuits could be used to solve a real-world problem.

Protein Fingerprinting

Science Fair Project Idea

Scientific Method

First came the Human Genome Project and now (drum roll please) the Human Proteome Project. Confused? Not surprising as the Human Proteome Project has not received the kind of press that the Human Genome Project did. Nonetheless it is a major, and potentially important, scientific undertaking. Just as the genome is the complete set of an organism's DNA, the proteome is all the proteins expressed in an organism. Why study the proteome? It is because proteins are the work horses of biological… Read more

Protein Structure and Function

Science Fair Project Idea

Scientific Method

How a biological system functions is a consequence of the 3-D structures of biological macromolecules like proteins and protein complexes. Proteins can be categorized into different protein families based upon sequence, structure, and function. Typically, proteins in the same family have similar biochemical functions. You can investigate the structure of a protein by using protein databases (Entrez Protein, SwissProt, PDB) and 3-D computational models. You can compare the structures of… Read more

Recording on a Wire

Science Fair Project Idea

Scientific Method

Today magnetic recording is used in audio and video cassette recorders, and computer disk drives. Did you know that you can also use an electromagnet to record and play back from a steel wire? In fact, this is how magnetic recording got started. This project shows you how to build a simple wire recorder. Read more

Seasonal Disease Outbreaks

Science Fair Project Idea

Scientific Method

"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others. Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to… Read more

Space elevators zipping people and materials up into space might seem like a very futuristic and improbable idea, but is it that difficult? This activity will guide you through the mathematics. Try it out and see what is possible with materials that can be produced with current technology. Read more

Study Chirality with a Homemade Polarimeter

Science Fair Project Idea

Scientific Method

Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many naturally occurring molecules have this property, called chirality. Chiral molecules can interact with polarized light in an interesting way—they rotate the plane of polarization. This chemistry science fair project describes how to make a homemade polarimeter… Read more

Taming the Tsunami: Investigating Different Structures to Reduce Tsunami Damage

Science Fair Project Idea

Scientific Method

On December 26, 2004, a magnitude 9.2 megathrust earthquake off the west coast of Sumatra, Indonesia unleashed a powerful tsunami that hit the coasts of 14 countries and caused the loss of over 200,000 lives. The devastation that the tsunami left in its wake was heartbreaking, and people across the world united to help the survivors. Tsunamis are a powerful force of nature that can change the features of a coastline and result in millions of dollars in economic loss, but can… Read more
