• Stephen Jay Gould. A paleontologist and historian of science: history and biology combined. Consider also his contribution to popular science and pop-science literature.

Biology Topics: Equipment

Come to think of it: every biologist needs tools! Why don’t you choose a piece of biological equipment (e.g., microscope) and discuss the history of its creation and its impact on the development of biology (or a specific branch of biology)? Here are some ideas for insightful equipment-related topics.

• Microscopes: using light and electrons to see this world in detail. Consider telling the brief history of the equipment and explaining its impact. Also, check out the two different types of microscopes.
• Test tubes: spin that sample right round! Who would need a test tube? Why? What for?
• Petri dishes. Culture your sample! Why is it called that way? What is it for? Consider discussing the history and impact of the invention.
• Dyeing your samples: when, why, and how? Tell the history of the development of the technique and the opportunities that it offers.
• How to tell a beaker from a flask? Check out the history of the two types of containers. What is its purpose? Why do they need to be different?

Biology Topics: Experiments

As you can see, your favorite biology field can make a significant research topic. But do you know what can make a biology paper most interesting? Cool bio experiments are out there! Tell your peers how to carry out a bio experiment or, better yet, show them! You can find some of the possible experiment topics below.

• What kind of biological organisms can be found in the samples of water from different sources? Offer examples of sources. If you want a practical demonstration, it is an excellent opportunity to use the microscope so that you can throw in some information about it too.
• How to extract your DNA at home? Discuss the necessary supplies and surprise your audience!
• What happens to an egg dipped in vinegar for too long? Discuss osmosis and its effects.
• If you cannot smell your food, will it taste the same? You can quickly organize a practical demonstration: just provide your audience with small snacks and ask them to cover their noses. Explain the mechanisms of smell and taste.
• How do you make your very own bacteria colony? This topic can be connected to that of the Petri dish.

Biology Topics: Sustainability and Biodiversity

Using a bio experiment as your topic can be great! However, apart from choosing the issues that are most interesting to you, you can find a problem, studying which is a responsible thing to do. For instance, sustainability is not just a buzz word. Discuss sustainability as a part of your bio project or paper and disseminate crucial information about preserving our planet’s resources!

• The concept of sustainability. Consider its history and impact on modern society.
• What biological resources do we need to preserve this day? Make sure to offer both classification and examples!
• Types of pollution. There are more than one, but why bother with the designation? Examples would be great here, too: check out the most devastating events in the history of ecology.
• An exciting element of sustainability is the preservation of biodiversity. Think about extinct species: what have we lost? What can we lose yet? And how do we stop the world from losing its precious biodiversity?
• Why is extinction a problem? Review the consequences of dying out.
• Causes of extinction. Is the human always to blame? Consider non-human matters. Can they be traced back to humanity?

Life science studies all forms of life, including plants, animals, viruses and bacteria, single-celled organisms, and even cells. Its key goal is to examine everything about life on this planet at different stages of evolution.
