Lung Capacity and Age

Science Fair Project Idea

Scientific Method

Our metabolism changes as we get older, a sad fact of life that we cannot change. Old age affects our bodies in many ways. Changes in musculature, bone strength, energy, diet and breathing are some of the many ways we change as we age. You might notice that people often get out of breath when they are older and doing a physical activity. Why do some people feel out of breath, while others do not? Does this change correlate with age? Could this reflect a difference in lung capacity between… Read more

Mapping Troposphere Ozone Levels Over Time

Science Fair Project Idea

Scientific Method

Ozone in the stratosphere protects the earth by absorbing harmful ultraviolet radiation from the sun. However, when ozone occurs in the troposphere, i.e., the air that we breathe, it is harmful to health. In this project you can use data from EPA monitoring stations to analyze the weather/climate conditions that can lead to harmful ozone levels. Read more

Measuring Antimicrobial Effectiveness with Zones of Inhibition

Science Fair Project Idea

Scientific Method

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate. Read more

Minimizing Bacteria in the Thawing and Cooking of Meat

Science Fair Project Idea

Scientific Method

How does your family thaw and cook meat? Have you ever wondered if it is the safest way? In this practical science project, you can find out and shed light on safe practices in the kitchen by investigating how many viable bacteria are present in samples of meat that have been thawed or cooked using different methods.

Multitasking: Brain Drain or Boost in Efficiency?

Science Fair Project Idea

Scientific Method

Think it's a good idea to plug into iTunes, surf the Web, or watch TV while doing homework or trying to read? Lots of people do it and claim that jumping from one activity to another keeps their attention level up and even gives their brain some time to "relax" between the more challenging tasks. Just how efficient is multitasking? In this project, you'll find out after testing the ability of volunteers to successfully do two or more things at once. Read more

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

Purification Strategies

Science Fair Project Idea

Scientific Method

In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project Extracting Onion DNA). The source of the material can be a cell… Read more

Shaping Your Thoughts?

Science Fair Project Idea

Scientific Method

This is an interesting experiment that explores certain aspects of how your brain pays attention. In this project, you'll have to recruit a bunch of volunteers to take a simple test: naming a list of printed shapes. What makes the test tricky is that words will be printed on top of the shapes. The word/shape combination creates the potential for the brain to get conflicting information. Which information is more likely to grab your attention: the shape you are supposed to name or the word just… Read more

Solubility of Proteins

Science Fair Project Idea

Scientific Method

Some proteins are soluble in aqueous solutions and some are not. Insoluble proteins can be a problem because the proteins can form large aggregates in solution which are difficult to purify, crystallize, and use in experiments. Compare the amino acid sequence and 3-D structures of some soluble and insoluble proteins (Berman, 2000). Is the structure polar or non-polar, and how might this affect solubility? How do detergents make an insoluble protein more soluble? Investigate how this… Read more
