Biology Research Topics for High School Students

Investigating the Effects of Different Environmental Factors on Plant Growth:

1. • Examining the impact of light intensity or different types of soil on plant growth.
   • Investigating the effect of different fertilizers or nutrients on plant growth and development.
   • Studying the influence of temperature variations on seed germination and plant growth.

Assessing the Antibacterial Properties of Natural Substances:

1. • Investigating the antibacterial effects of common household substances like garlic, honey, or vinegar.
   • Examining the efficacy of natural plant extracts as antibacterial agents.
   • Studying the impact of different concentrations of a specific natural substance on bacterial growth inhibition.

Comparing the Effects of Different Exercise Types on Heart Rate:

1. • Investigating the impact of aerobic exercise, such as running or swimming, on heart rate.
   • Comparing the effects of different types of exercise, like weightlifting or yoga, on heart rate response.
   • Studying the recovery time of heart rate after various exercise intensities.

Exploring the Effect of Different pH Levels on Enzyme Activity:

1. • Investigating the impact of pH on the activity of an enzyme, such as catalase or amylase.
   • Comparing the enzyme activity at different pH levels to determine optimal conditions.
   • Studying the effects of extreme pH levels on enzyme denaturation.

Investigating the Impact of Different Music Genres on Human Brain Activity:

1. • Analyzing the effects of classical music, rock music, or other genres on brainwave patterns using electroencephalography (EEG).
   • Studying the relationship between music tempo and brainwave frequency.
   • Investigating the emotional and physiological responses to different music genres.

Examining the Diversity of Microorganisms in Local Water Sources:

1. • Collecting water samples from various local water bodies and identifying the microbial communities present.
   • Studying the relationship between water quality parameters (pH, temperature, pollution levels) and microbial diversity.
   • Analyzing the potential presence of indicator organisms to assess water quality.

Investigating the Impact of Different Food Preservatives on Mold Growth:

1. • Studying the effects of common food preservatives (e.g., salt, vinegar, sugar) on mold growth.
   • Comparing the effectiveness of different concentrations of a specific food preservative on mold inhibition.
   • Examining the impact of preservatives on mold growth under different environmental conditions.

Remember to choose a topic that aligns with your interests and resources available. Conduct thorough research, design appropriate experiments, and document your findings accurately. Additionally, ensure safety measures are in place when conducting experiments and seek guidance from your teacher or a mentor throughout the research process.
