Wondering about how to choose a chemistry ia topic? Let’s start with simple factors that can help you identify the best topic;

• Identify a topic associated with your hobby.
• Avoid topics that relate directly to your textbook experiments. Be creative.
• Ensure a topic is relevant to your syllabus
• Consider your resources, such as lab apparatus, when picking a topic
• Ensure there is depth in your topic, enough for analyzing and interpreting the results

Are you struggling with time, and are your Chemistry IA topics deemed too obvious? Here is a list that can inspire you;
