I need a Biology IA (Individual Investigation) topic, Im desperate so can I have a topic and not tips?

Here's a potential topic for your Biology IA:

Topic: Investigating the Effects of pH on the Activity of Amylase Enzyme

In this investigation, you can explore how different pH levels affect the activity of amylase, an enzyme that breaks down starch into simpler sugars. This topic aligns with the IB Biology syllabus and allows you to apply laboratory techniques to measure enzyme activity under various conditions.

Research Question: How does the pH of a solution affect the activity of amylase enzyme in breaking down starch?

Methodology:

• Prepare buffered solutions with different pH levels.
• Use amylase to catalyze the breakdown of starch in each solution.
• Measure the rate of starch breakdown by tracking the formation of reducing sugars or the disappearance of starch.
• Control variables such as temperature, substrate concentration, and enzyme amount.

This topic is manageable, relevant to the curriculum, and allows for interesting data analysis and discussion.
