Starting a Science Project

What Makes A Good Science Project?

Some advice from a science fair judge

The Parts of a Science Project

The idea behind a science project is to discover "what happens if." What happens to one thing if you change something else?

Science Fair Projects: Understanding and Using the Scientific Method

The scientific method is extremely important to your science fair project, and understanding it is critical to the success of your science fair experiment.

Biology Science Projects For Beginners

Which Foods Do Molds Love Best?

Figure out on what kinds of foods, and under what conditions, molds grow best. Do they prefer light or darkness, wet foods or dry foods, and heat or cold?

For reference: Mold, Slime Mold, Fungal Infections

What Foods Attract Ants?

Ants have a chemical sensory aid that directs them to the foods they love the most. Experiment to determine which foods from your kitchen ants like best.

For reference: Ants, Fats, Carbohydrates, Protein

Do Loud Noises Affect Heart Rate?

Reflexes are sort of an automatic safety response system in your body, and they work to protect you from harmful situations. Try to find out whether loud noises affect the rate at which a person's heart beats.

For reference: The Nervous System and Reflexes, Pulse, Heart

Biology Science Projects For Intermediate Levels

How Fast Are You? Testing and Measuring Reflexes

Look at the reaction time—or reflexes—and how it varies between younger and older people. Do older people have slower reaction times than younger people?

For reference: The Nervous System and Reflexes

Determining Your Speediest Shoes

Which pair of shoes helps you to run the fastest—sneakers, sandals, or dress shoes?

Does Caffeine Increase Heart Rate?

Does caffeine affect the rate at which a heart beats?

For reference: Pulse, Heart, Caffeine, Caffeine Content of Selected Foods

Biology Science Projects For Advanced Levels

Is the DNA of a Cow Different from a Chicken's?

Learn how to extract DNA from its nucleus to compare the DNA from the chicken liver with that from the cow liver to see if they're different.

For reference: DNA (Nucleic Acid), The Chemistry of Biology: Nucleic Acids, Genetic Engineering

Do Plants Sweat Like People Do?

It's called transpiration, and it's when plants release water through their leaves.

For reference: Transpiration

What Types of Bacteria Are Found in Your House?

Bacterial organisms are everywhere. Do this experiment to find what areas in your home have the most bacteria.

For reference: Bacteria, Petri Dish, How did the petri dish get its name?
