Human body science projects allow people to better understand the human body. Not only do these studies help researchers improve their knowledge of anatomical functions, but they also offer insight into human behavior. Scientists and students alike should be well acquainted with human physiology. The following lists provide topic suggestions for simple experiments to conduct that will help you learn more about the complexities of the human body.

Behavioral Project Ideas

Mood and Disposition

  • Does the weather affect a person's mood?
  • Does smiling affect a person's mood?
  • Do colors affect a person's mood?
  • Does human behavior change during a full moon?
  • Does room temperature affect concentration?
  • How does amount of sleep affect a person's concentration?

Systems

  • Does music affect blood pressure?
  • How does fear affect blood pressure?
  • How does caffeine affect the body?
  • Does exercise affect memory retention?
  • Does biological sex affect reaction time?
  • How does a person's heart rate respond differently to short bursts of intense exercise vs. long stretches of steady exercise?

Senses

  • Does your sense of smell affect your sense of taste?
  • Which sense (taste, smell, touch) is most effective for food identification?
  • Does sight affect the ability to determine the source or direction of sound?
  • How do sounds (e.g. music) affect hand-eye coordination?
  • Is a person's sight altered (short-term) after playing video games?

Biological Project Ideas

Systems

  • Does a person's BMI affect their blood pressure?
  • What is the average normal body temperature?
  • Which types of exercise are most effective for increasing muscle growth?
  • How do various types of acid (phosphoric acid, citric acid, etc.) affect tooth enamel?
  • How do heart rate and blood pressure vary during the day?
  • Does exercise affect lung capacity?
  • Does blood vessel elasticity affect blood pressure?
  • Does calcium impact bone strength?

Senses

  • Do food smells affect saliva production?
  • Does eye color affect a person's ability to distinguish colors?
  • Does light intensity affect peripheral vision?
  • Do different stressors (heat, cold, etc.) affect nerve sensitivity?
  • How is sense of touch affected by scar tissue?
  • What is the highest and lowest frequency that the average person can hear?
  • Does the heat of food impact the effectiveness of different types of taste (salty, sour, sweet, bitter, umami)
  • Is sense of smell or sense of touch more useful in effectively identifying unknown objects without the use of other senses?
