pH, pOH, H3O+, OH-, Kw, Ka, Kb, pKa, and pKb Basic Calculations -Acids and Bases Chemistry Problems Teacherflix 36 Views • 2 years ago

This acids and bases chemistry video tutorial provides a basic introduction into the calculation of the pH and pOH of a solution. This video explains how to the calculate the hydronium ion [H3O+] and the hydroxide ion [OH-] concentration given the pH or the pOH of the solution. This video contains the formulas and equations needed to calculate Ka and Kb using Kw as well as the pKa and pKb of acids and bases. This lesson contains plenty of examples and practice problems.

Herbivores, Carnivores, and Omnivores for Kids | Learn which animals eat plants, meat, or both

Herbivores, Carnivores, and Omnivores for Kids | Learn which animals eat plants, meat, or both Teacherflix 47 Views • 2 years ago

Do you know the difference between herbivores, carnivores, and omnivores? Do you know which one you are? In this video for kids, you will learn all about the three diets that animals (and even a few plants!) follow. You will also learn what exactly these three words mean.

One of the main characteristics that distinguishes the type of diet an animal will follow is the teeth. Herbivores only eat plants. These animals tend to have dull or no canine teeth and big, flat side and back teeth. They use their molars to crush and grind the plants they consume. Examples include sheep, cows, giraffes, rats, and grasshoppers. You could consider herbivores vegetarians!

Carnivores, on the other hand, only eat meat. They have long and sharp canine teeth next to their front teeth. They also have sharp cheek teeth called carnassials that help them cut up meat in their mouths. Carnivorous animals include lions, spiders, sharks, wolves, dragonflies, and the Venus fly-trap (which is actually a plant).

Finally, that leaves us with omnivores, which eat both plants and animals. Humans are omnivores because we consume both types of food. Omnivores have a combination of flat teeth and sharp teeth because they eat both plants and animals. Apart from humans, other omnivores include lizards, turtles, apes, catfish, and bears.

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

Food Groups for Kids | Learn about the five food groups and their benefits

Food Groups for Kids | Learn about the five food groups and their benefits Teacherflix 21 Views • 2 years ago

Do you know what the five food groups are? Do you know which foods fall into each category? In Food Groups for Kids, you will learn about the benefits that foods in each of these groups provide your body and keep you healthy. You will also discover how many servings a day you should have of each one.

Fruits include things like apples, nectarines, and bananas. They provide your body with lots of essential vitamins and nutrients. Vitamin C and potassium are two very important vitamins and minerals that your body needs. Vegetables like carrots and spinach may not be as sweet as fruits, but they have tons of vitamins and nutrients that you need as well!

Grains probably makes you think of bread and cereal. This group also includes pasta, tortillas, and popcorn! These foods also provide you with fiber, which helps your body do a lot of good things. Next are proteins, which include foods like meat, fish, beans, and tofu. They can provide your body with energy and help your bones and muscles grow strong. Similarly, dairy products can also strengthen your bones, and give you vitamin D to help reduce your risk of diseases.

Each group requires a different number of servings each day. And those serving sizes differ as well. Fruits, for instance, require 1 1/2 cups per serving while proteins require 5 ounces per serving. Some foods even contain multiple food groups in one place, like pizza, which can have grains from the bread and toppings from the other four groups.

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

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

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.
