Safety in the Life Sciences 01:21

10

Safety in Life SciencesSafety is one of the most important aspects of working in the life sciences. Whether you're conducting an experiment in the lab, studying plants and animals outdoors, or handling biological materials, following safety rules helps protect you, your classmates, and the environment. Adhering to these rules allows us to conduct science safely without accidents, contamination, or health risks.Science and Engineering Practices (SEP - Planning and Carrying Out...

Basic and Applied Science 01:22

3

Basic and Applied ScienceScience is divided into two main areas: basic science and applied science. Basic science focuses on understanding the natural world and discovering new knowledge. Scientists study how things work, even if there is no immediate practical use for the information. Applied science takes discoveries from basic science and uses them to develop solutions to real-world problems. This includes advancements in medicine, engineering, and technology. Both types of science work...

Scientific Method 01:15

Scientific Method The scientific method is a structured way to answer questions and test ideas. Scientists follow these steps to ensure their investigations are organized and reliable.Scientists use the scientific method to explore questions and solve problems. They begin by identifying a question they want to investigate. Next, they conduct background research to gather information and gain a better understanding of the topic. Based on this research, they develop a hypothesis, an educated...

Mass Extinction 01:17

Mass ExtinctionMass extinction occurs when many species disappear from Earth in a short period. Throughout Earth’s history, five major mass extinctions have been caused by asteroid impacts, volcanic eruptions, or sudden climate changes. These events drastically reduced biodiversity and led to the evolution of new species over time. Today, scientists believe we are facing a possible sixth mass extinction, driven by human activities such as deforestation, pollution, climate change, and habitat...

Scientific Ways of Thinking 01:31

56

Scientific Ways of ThinkingScientific thinking is about asking questions, testing ideas, and using evidence to find answers. Instead of just guessing, scientists observe, experiment, and analyze to understand how things work. They follow steps called the scientific method, which involve making a hypothesis, testing it, and looking at the results. You use this kind of thinking, too. Have you ever tried different ways to fix a broken toy or figure out why your electric bicycle won’t move...

Lab SafetyLab safety is an important part of doing science. Following safety rules in the laboratory helps prevent accidents and ensures that experiments are carried out safely. Scientists follow strict safety procedures when working with chemicals, heat, or equipment, and students should do the same. Knowing and following lab safety rules helps keep everyone safe while conducting scientific research.Important Lab Safety RulesWear Safety Gear – Always wear goggles, gloves, and lab aprons when...
