Water Bodies for Kids | What are the different bodies of water?
Water Bodies for Kids | What are the different bodies of water? Teacherflix 4 Views • 2 years ago

What is an ocean? What is a lake? What do you call water that flows down a mountain? In this video, you and your kid(s) will learn all about the many bodies of water that cover the earth. You will discover what to call both the largest and smallest water bodies. Over 70% of the earth's surface is made up of water. That means there is more than double the amount of water than there is land!

Some bodies of water are made up of salt water. Others, such as many lakes and streams, contain fresh water. There is a lot more salt water than fresh water, though. Over 95% of water sources are salt water. That's because most of the water on the planet comes from oceans, which are by far the biggest water bodies. Not to mention, the deepest part of the ocean is deeper than the height of Mt. Everest! Scientists believe there are around a million species living in the ocean! While trees convert carbon dioxide to oxygen, did you know about 70% of Earth's oxygen supply actually comes from phytoplankton in the oceans?

You will also learn about reservoirs and lakes. Reservoirs are essentially man-made lakes. People create man-made lakes or reservoirs by damming up a river, holding back a lot of water in one place. The largest freshwater lake in the world is Lake Superior, which is located between Canada and the United States.

Rivers are unique in their own way. Rivers can flow down mountain, through valleys, or across plains. They flow toward either an ocean, a sea, a lake, or another river. They are very useful because they provide food, transportation, power, and a place to bathe! The Amazon and Nile Rivers are the two longest rivers. You will also learn about streams, which are kind of like mini rivers. They also come with a lot of different names, such as bayou, creek, and wash.

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

ASL Landforms for Kids
ASL Landforms for Kids Teacherflix 8 Views • 2 years ago

Do you know what mountains, hills, plateaus, and plains have in common? This video teaches kids all about landforms, particularly these four. Your kids will learn all about the different types and how they form. They will discover many interesting facts. For instance, they will learn about the Himalayas and how they make up the tallest mountain range in the world. Mount Everest is the tallest peak of the Himalayas. It's as tall as 48,000 people standing on each others' shoulders!

Hills are similar to mountains. They aren't as tall, but they form in similar ways. In fact, some mountains, including the Himalayas, started out as hills! Did you know there are two types of plateaus? All plateaus are flat and elevated, and they have steep hills and big cliffs. However, not all plateaus are the same. Dissected plateaus are created from tectonic shifts from the ground up. The Colorado Plateau is one of these. Volcanic plateaus, however, are formed from many small volcanic eruptions that build up over time. Most of the central part of the North Island of New Zealand. You will also learn about plains and how they are unique compared to the other three landforms.

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

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

FIRST LADY Melania Trump & HUMANOID ROBOT at AI education summit
FIRST LADY Melania Trump & HUMANOID ROBOT at AI education summit Teacherflix 1 Views • 21 days ago

First Lady Melania Trump turned heads on Wednesday morning at the White House, but not for her usual high-class fashion statements.

On day two of the Fostering the Future Together Global Coalition Summit, Mrs. Trump was seen walking out with a humanoid robot built in the United States as she was prepared to speak to leaders from 45 nations and 28 best-in-class technology entities.

Like a scene out of a sci-fi movie, the robot named Figure 03 gave brief remarks and welcomed roundtable guests in their native languages.

"It's fair to state you're my first American-made humanoid guest in the White House," Melania quipped before joining leaders.

ComAI Lecture with Prof. Dr. Jeremy Knox (U of Oxford):
ComAI Lecture with Prof. Dr. Jeremy Knox (U of Oxford): Teacherflix 1 Views • 21 days ago

Abstract
In a similar way to previous education technologies, recent developments in artificial intelligence (AI) are typically discussed in terms of their ability to enhance learning or make the educational process more efficient. While this dominant discourse is sometimes countered with concerns about the potential harm to ‘humanistic’ notions of learning, general debates are often stymied by an opposition between ‘benefits and drawbacks’. Discussion of the use of Large Language Models (LLMs) in education, for example, often seems to oscillate between predictions of grand transformations in knowledge production and concerns over cheating in assessments.
This talk will suggest that, rather than a habitual focus on the potential enhancement or impairment of learning, a richer understanding of the impact of AI on education might be developed through an analysis of power. This will focus on the ways AI systems increasingly produce, collect, and organise data, drawing on Isin and Ruppert’s (2020) discussion of four overlapping forms of modern power – sovereign, disciplinary, regulatory, and sensory. It is in this way that AI might be understood, not as an instrument of power, or a ‘tool’ through which better or worse educational outcomes can be determined, but rather as a technology through which power produces effects. The use of AI in education will be suggested to both consolidate historical forms of governance through education, as well as enact new assemblages of power in an era of datafication. Resistance to such power will be suggested to come from a return to educational notions of subversion and opacity.

Bio
Jeremy Knox is Associate Professor of Digital Education at the Department of Education, University of Oxford, and an Official Fellow of Kellogg College. His research interests include the relationships between education, data-driven technologies, and wider society, and he has led projects funded by the ESRC and the British Council in the UK. Jeremy has previously served as co-Director of the Centre for Research in Digital Education at the University of Edinburgh, and currently co-convenes the Society for Research in Higher Education Digital University network. His published work includes AI and Education in China (2023), Data Justice and the Right to the City (2022), The Manifesto for Teaching Online (2020), Artificial Intelligence and Inclusive Education (2019), and Posthumanism and the Massive Open Online Course (2016).

Cosmology & Astronomy on Khan Academy: The Earth is huge, but it is tiny compared to the Sun (which is super huge). But the Sun is tiny compared to the solar system which is tiny compared to the distance to the next star. Oh, did we mention that there are over 100 billion stars in our galaxy (which is about 100,000 light years in diameter) which is one of hundreds of billions of galaxies in just the observable universe (which might be infinite for all we know). Don't feel small. We find it liberating. Your everyday human stresses are nothing compared to this enormity that we are a part of. Enjoy the fact that we get to be part of this vastness!
