In the second half of our look at the endocrine system, Hank discusses chemical homeostasis and hormone cascades. Specifically, he looks at the hypothalamus-pituitary-thyroid axis, or HPT axis, and all the ways your body can suffer when that system, or your hormones in general, get out of whack.

Valence Electron Basics
Learn how to use the periodic table in order to determine the number of valence electrons.
The valence electrons are the electrons found in the outer shell of an atom. The outer shell is also called the orbitals or the atomic electron shells.
I also show two methods of illustrating the valence electrons.
The Bohr diagram and the Lewis dot structure.

addition and subtraction of fractions | How To Simplify Fractions | how to add fractions with different denominators | addition of mixed fractions

in this video we will learn How do you add fractions with different denominators?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
Another way is using the cross multiplication the fractions can be solved.

Have you ever wondered "What is Biofuel?" or "What is Biomass?" The need for energy is ever growing and biofuels and biomass are different materials that can be used for energy. Biomass and Biofuel are considered renewable energy because it mostly comes from plants that can be replanted and replaced when used for energy. In this video we will discuss all kinds of energy and the advantages and disadvantages to biomass or biofuel vs fossil fuels.

We also invite you to download our free biofuel and biomass lesson plan here: https://learnbright.org/lesson....s/science/biomass-an in this lesson and video students learn about specific examples of both biomass and biofuel and learn the advantages and disadvantages of using them through engaging content, worksheets, activities and more!

👉 Learn how to solve two step linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. To solve for a variable in a two step linear equation, we first isolate the variable by using inverse operations (addition or subtraction) to move like terms to different sides of the equality sign. After evaluating like terms we then also use inverse operations (multiplication or division) to remove any multiple (or fraction) to the variable.

This quick tutorial shows you how to find a missing variable when trying to make equivalent fractions. You can perform cross-multiplication of the numerator from the first fraction to the denominator of the second fraction. Then divide that product by the other known variable.

Learn all about the 5 Oceans of the World in this video designed for kids and elementary students. We walk through the geographic locations for each ocean and share some unique facts about each area. We hope you enjoy learning all about our Oceans. For more resources download our comprehensive lesson plan found here:

Oceans of the World: https://learnbright.org/lesson....s/science/oceans-of-

What Lives in the Oceans: https://learnbright.org/lesson....s/science/what-lives

The Oceans of the earth are vast…they are humongous! Over 72% of the earth is covered with water called Oceans and Seas

There are five major Oceans of the world, and although these Oceans are all connected, they each have a different name. They are; The Pacific Ocean…the Atlantic Ocean…the Indian Ocean…The Southern Ocean (also called the Antarctic Ocean) …and the Arctic Ocean.

Here are some specific facts about each ocean.

Pacific Ocean: Located between the continents of Asia, N./S. America & Australia
~The largest of the 5 oceans, covers 30% of the Earth’s surface.
~ The word Pacific means peaceful, but the ocean is not calm or peaceful.
~ Many volcanoes are located in the ocean: The “Ring of Fire”.
~ The deepest part is nearly 7 miles below the surface.
~ The Great Barrier Reef is located off the Australian coast.

Atlantic Ocean: Located between the continents America, Europe, and Africa
~ About half the size of the Pacific Ocean
~ Many sharks are found in the waters of the ocean.
~ Islands located in the Atlantic include the Bahamas and Greenland, which is the largest island on Earth.
~ The word Atlantic means “Sea of Atlas”.
~ Cities on the Atlantic Ocean include Miami and London.

Indian Ocean: Located between Africa, Australia and parts of Asia
~ Largest breeding grounds of the world for humpback whales.
~ The Suez Canal in Egypt is a waterway in the ocean.
~ Cities along the ocean include Mumbai, India; Perth, Australia;
and Singapore.
~ Many endangered species live here such as turtles and seals.

Arctic Ocean: Located around the North Pole across the Arctic circle
~ Home to many of the Polar Bears of the world.
~ Smallest ocean and most shallow, but is the coldest.
~ Sometimes called the “frozen ocean”, almost completely covered in ice during the winter,
~ There are more fish species here than anywhere else in the world.

Southern Ocean: Located around the South Pole across the Antarctic circle
~ Home to the Emperor Penguins and Wandering Albatrosses
~ Sometimes it is also called the Antarctic Ocean
~ Icebergs are found throughout the Southern Ocean
~ No people live along the coast of the ocean

Once, British ruled over one fourth area of the world. It was said that the sun never sets on the british empire. That is why, English became a global language.
In this video, we explore the fascinating history of how English became a global language. From the British Empire to modern-day pop culture, we examine the reasons behind the language's worldwide prevalence. We also delve into the statistics of English speakers in India and beyond, and ultimately, stress the importance of speaking and listening in language learning.

I’m going to show you one of the most enduring electronic prototyping boards of the past 10 years. It’s not an Arduino or a Raspberry Pi. It’s this – the Makey Makey.

And it doesn’t get the respect it deserves. It’s a no-code solution targeted toward students, but you’ll see it pop up everywhere. Most recently, I found it being used in half a dozen of the custom made arcade games of Alt.CTRL GDC.

What it does is translate a broad range of input into computer keystrokes. Yes, you can use tinfoil or bananas to control a computer game, but also if you’re prototyping something like a kiosk, it’s also a super quick way to wire up simple button controls to a Raspberry Pi.

You can find the Makey Makey starter kit on Digi-Key, and you can find more maker tips like these on Maker Update, each week on the Digi-Key YouTube channel.

Transparent material allows visible light to pass through it. Some of the light may be absorbed, but it is possible to see objects through the material.
Translucent materials allow some light through them but it is scattered so it is impossible to see a clear image through the material.
Opaque materials don't let light through them at all. The light is either reflected or absorbed.

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

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.
