Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

ASL What Is a Volcano? for Kids Teacherflix 11 Views • 2 years ago

How many active volcanoes do you think there are in the world? What makes a volcano active versus dormant or extinct? In What Is a Volcano? for Kids, you and your students will learn the answers to the questions and more. Plus, you can conduct an experiment where you make your own model volcano!

A volcano is a mountain made from cooled lava, ash, or other material from previous eruptions. Some even exist on the ocean floor. There are over 1500 active volcanoes in the world today. Every day, 15 to 20 volcanoes erupt somewhere. In the United States, there are active volcanoes in Hawaii, Alaska, California, Oregon, and Washington. Movements of the earth's crust cause volcanic eruptions.

What's the difference between magma and lava? Magma is located beneath the earth's surface. It is made of liquid or semi-liquid rock. After gas bubbles inside the magma expand and build up the pressure in the volcano, the volcano erupts. Once the magma escapes the volcano, we call it lava. The more often a volcano erupts, the larger it becomes as the lava cools and builds up the volcano.

Keep watching to follow along with a fun experiment to see how volcanoes work. You can pause the video when prompted to make sure you gather all the necessary supplies (and people). For more detailed instructions, check out the link below to our Earthquakes and Volcanoes STEM lesson plan. Hope you enjoy!

We hope you and your student(s) enjoyed learning about volcanoes! If you want to learn even more, head over to our website and download one of our many free lesson plans about these natural features, full of activities, worksheets, and more!

ASL Laws and Rules for Kids Teacherflix 8 Views • 2 years ago

What is the difference between a rule and a law? What would life be like if neither rules nor laws existed? In Laws and Rules for Kids, you will discover the answer to these and other questions you have about these concepts. They have similarities, such as the fact that both exist to keep people safe. But they are also different in a few ways. For instance, if you break a law, it may have more serious consequences than breaking a rule does.

A law is created by the government, and the public enforces these laws. A rule relates to behaviors that we should follow in certain situations or places. Breaking a law and breaking a rule both lead to consequences. If you litter, which is breaking the law, you might have to pay a fine. If you throw a ball inside your house even though there is a rule not to, you might break something and get in trouble.

In general, rules are used by smaller groups, like families, schools, teams, and business. Laws are used in much larger groups, like cities, states, and countries. Individuals create rules for different places and situations, such as parents in a family or teachers in a classroom. On the other hand, laws must be voted on by people in government offices or by the citizens.

Again, the consequences or punishments for breaking rules are not as severe as those for breaking laws. If you break rules at school, you might have to skip recess or miss out on certain activities or privileges. If you break a law, you could pay a fine, go to court, do community service, or even serve jail time! Watch the video to see if you can tell the difference between a rule and a law.

We hope you and your student(s) enjoyed learning about the difference between a rule and a law! If you want even more information, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!
