10 Different Bio IA Topic Ideas to choose

Here are ten topic ideas for an IB Biology Internal Assessment that require an experiment, along with a brief explanation of what an IB student could do to work on these topics:

  • The effect of volume and pH of carbonated drinks on the dental erosion or decay of teeth: 

This topic involves the study of the effects of different volumes and pH levels of carbonated drinks on the erosion or decay of teeth. An IB student could conduct an experiment to test the effects of different volumes and pH levels of carbonated drinks on teeth and analyze the results to determine the impact on dental health.

  • The effect of different types of light on the growth of plants: 

This topic involves the study of the effects of different types of light on the growth of plants, including the intensity and wavelength of the light. An IB student could conduct an experiment to test the effects of different types of light on the growth of plants and analyze the results to determine the optimal conditions for plant growth.

  • The effect of different temperatures on the rate of enzyme-catalyzed reactions: 

This topic involves the study of the effects of temperature on the rate of enzyme-catalyzed reactions, which are essential for many biological processes. For example, an IB student could conduct an experiment to test the effect of different temperatures on the rate of an enzyme-catalyzed reaction and analyze the results to determine the optimal temperature for the reaction.

  • The effect of different concentrations of a chemical on the rate of a chemical reaction: 

This topic involves the study of the effects of different concentrations of a chemical on the rate of a chemical reaction, which can be influenced by the availability of reactants. For example, an IB student could conduct an experiment to test the effect of different concentrations of a chemical on the rate of a chemical reaction and analyze the results to determine the optimal concentration for the reaction.

  • The effect of different pH levels on the growth of bacteria: 

This topic involves the study of the effects of different pH levels on the growth of bacteria, which can be influenced by the acidity or basicity of their environment. For example, an IB student could conduct an experiment to test the effect of different pH levels on the growth of bacteria and analyze the results to determine the optimal pH for bacterial growth.

  • The effect of different concentrations of oxygen on the respiration rate of yeast: 

This topic involves the study of the effects of different concentrations of oxygen on the respiration rate of yeast, which is an important process for the production of energy in cells. An IB student could conduct an experiment to test the effect of different concentrations of oxygen on the respiration rate of yeast and analyze the results to determine the optimal oxygen concentration for respiration.

  • The effect of different types of fertilizers on the growth of plants: 

This topic involves the study of the effects of different types of fertilizers on the growth of plants, including the nutrient content and pH of the fertilizers. An IB student could conduct an experiment to test the effect of different types of fertilizers on the growth of plants and analyze the results to determine the optimal fertilizers for plant growth.

  • The effect of different levels of salt on the germination of seeds: 

This topic involves the study of the effects of different levels of salt on the germination of seeds, which is the process by which a plant sprouts from a seed. An IB student could experiment to test the effect of different levels of salt on the germination of seeds and analyze the results to determine the optimal conditions for seed germination.
