The complex nature of living things make biology a fascinating, albeit often challenging, topic. Motivate listeners to dedicate themselves to the study of this subject by preparing engaging presentations that center on some of the most intriguing biology topics. By doing so, you can highlight the excitement inherent in biology and motivate others to explore the science of living things.
Because it touches the lives of all living things in amazing ways, genetics is a high-interest biology topic. In your presentation on this topic, discuss the ways in which genetic material is passed from one generation to the next, exploring potential outcomes of genetic combinations and helping listeners gain a better understanding of how they acquired their genetic material. Also explore the concept of genetic mutation, as this is often of interest to listeners due to its complexity and the oddities that can result from these mutations.
Cloning was once a thing of science-fiction only, but now the process has become an element of science-fact. Discuss cloning, how it works and what could be done through the use of this technology with your listeners. Explore major milestones in the cloning process, such as the cloning of Dolly the sheep, as well as legalities associated with this practice. Conclude your presentation by exploring the ethical dilemmas associated with this practice, helping listeners understand why it is so hotly contested.
Functions of the Brain
The brain is a constant source of scientific interest. Because this organ is so complex, even scientists who have studied it for decades are far from fully understanding exactly how and why it works. You certainly cannot answer every question that exists about this amazing organ, but you can pique listeners’ interests by giving them a taste of what this scientific marvel can do. In your presentation, discuss the concept of brain injuries, exploring how the brain can recover from trauma. Also explain the differences between the right brain and the left brain, telling your listeners how each of these hemispheres influences the ways in which humans behave.
Were it not for animal adaptations, many species would have long ago been erased from the planet. Camels, for example, could not survive in their largely inhospitable desert environment were it not for their water-storing humps. Explain how animal adaptations help living things survive, giving examples of some of the more visibly apparent adaptations. Also discuss how these adaptations came to be, explaining that animals evolved over generations to have these life-saving adaptations within their species.
