Human Body Project Ideas

Human body science projects and studies allow us to get a better understanding of the human body. Not only do we gain an improved knowledge of anatomical functions, but we gain a greater understanding of human behavior as well. The following human body project ideas provide suggestions for topics that can be explored through experimentation.

• Does your sense of smell alter your sense of taste?
• Which sense (taste, smell, touch) is best for identifying foods?
• Does music affect blood pressure?
• Does fear affect blood pressure? (Fear Science Project - Sample)
• How does caffeine affect the body?
• Does exercise affect memory retention?
• Does music affect hand-eye coordination?
• Does the weather affect a person's mood?
• Does playing video games affect a person's heart rate?
• Do colors affect a person's mood? (Colors and Mood Project - Sample)
• Does gender affect reaction time?
• Is yawning contagious?
• Does smiling affect a person's mood?
• Does human behavior change during a full moon?
• Does room temperature affect concentration?
• Does sight affect the ability to determine sound direction?

• Does a person's BMI affect blood pressure?
• Do all people have the same normal body temperature?
• Which type of exercises increase muscle growth the most?
• How do various types of acid (phosphoric acid, citric acid, etc.) affect tooth enamel?
• Does a person's heart rate and blood pressure vary during the day?
• Does exercise affect lung capacity?
• Does blood vessel elasticity affect blood pressure?
• Is calcium necessary for bone strength?
• Does light intensity affect peripheral vision?
• Does eye color affect a person's ability to distinguish colors?
• Do different stressors ( heat, cold, etc.) affect nerve sensitivity?
• Do food smells affect saliva production?

Constructing models is a fun and exciting way to learn about science. Try making a model of the lungs or making a DNA model using candy. It is important to note that just constructing a model is not an experiment. Models should be used to enhance your science project.
