Chemistry, often called central science, is a branch of science that studies the properties, composition, structure, changes, and interactions of matter at the atomic and molecular levels. It is a fascinating field that has wide-ranging applications in various aspects of our daily lives, from the food we eat to the medicines we take, from the materials we use to the environment we live in.
Chemistry is fundamentally based on the concept of atoms, which are the building blocks of matter. Atoms are the smallest units of an element that retain the properties of that element. The periodic table, which is a tabular arrangement of elements based on their atomic numbers, is a fundamental tool in chemistry. It provides important information about the properties and behavior of different elements, such as their atomic masses, electronic configurations, and chemical reactivity.
Chemical reactions are at the heart of chemistry. They involve the transformation of one or more substances into new substances with different properties through the breaking and forming of chemical bonds. Chemical reactions can be classified into various types, including synthesis, decomposition, combustion, redox, and acid-base reactions, among others. Understanding the principles and mechanisms of chemical reactions is crucial in many aspects of chemistry, from designing new drugs to developing sustainable energy sources.
Chemistry also encompasses the study of different states of matter, such as solids, liquids, gases, and solutions. The behavior and properties of matter can change significantly depending on its state and chemistry provides the tools and theories to understand and manipulate these changes. For example, the study of thermodynamics, which deals with the energy changes in chemical systems, is crucial in understanding and predicting the behavior of matter under different conditions, such as changes in temperature, pressure, and concentration.
Speaker Guidelines
Organize Your Research
State the hypothesis and purpose of your research.
Describe your methods of investigation.
Include data collected and what was learned.
Give conclusions based on the collected data.
Emphasize the significance and highlights of the research.
Shape Your Presentation
Prepare notes that highlight the salient points of your talk.
Practice the delivery of your talk, along with your slide sequence. Be sure your talk fits the time allotted.
Use simple sentences. Avoid jargon, highly specialized vocabulary, and unfamiliar abbreviations.
Think about questions you might be asked, and prepare your answers.
Audio-visuals should amplify your talk, not duplicate it.
Do not include music or film clips or other copyrighted content with your presentation unless it is directly relevant to your research. If you must include music, film clips, or similar content, please ensure that it is either open source or content for which you have copyright permissions to use. Optimally display your work—don't use words if a picture conveys it more clearly (graphs, tables, charts, etc.).
Use line graphs to show trends; bar graphs to compare magnitudes; pie graphs to demonstrate relative portions of a whole.
Make sure your supporting audio-visuals are concise, uncluttered, and easily read from a distance. We recommend that you use a font of at least eighteen points or larger. This is especially important in presentations to a virtual audience because screen sizes vary by user.
Request special AV equipment early or it may not be available.
