Did you know the forces of nature like wind or weather change the physical structure of how things look over time? In this video for kids, you will learn all about the processes of weathering and erosion. You will discover that there are three main types of weathering and three main types of erosion. The two process seem pretty similar, but they are actually different. But they practically work together to both destroy landforms and create new ones!

The three types of weathering are chemical, mechanical, and biological. Chemical weathering changes minerals inside or on the surface of rocks. Mechanical weathering is caused by ice, the sun's heat, and a couple other natural forces. Biological weathering involves plants and animals, as well as humans. It is called "biological" because this type of weathering happens because of a living organism. For instance, a tree root growing out of a rock is slowly breaking that rock into smaller pieces.

The three main causes of erosion are water, wind, and ice. Water can cause erosion through rainfall, rivers, and floods. The force of water pushes or pulls rocks and sediment to a new location. Wind similarly picks up and carries loose particles and dust. And glaciers are constantly moving and shifting, which causes erosion too!

We hope you and your student(s) enjoyed learning how the earth changes! If you want even more information, head over to our website and download one of our many free lesson plans about weathering and erosion, full of activities, worksheets, and more!

In which John Green teaches you about the presidency of Andrew Jackson So how did a president with astoundingly bad fiscal policies end up on the $20 bill? That's a question we can't answer, but we can tell you how Jackson got to be president, and how he changed the country when he got the job. Jackson's election was more democratic than any previous presidential election. More people were able to vote, and they picked a doozie. Jackson was a well-known war hero, and he was elected over his longtime political enemy, John Quincy Adams. Once Jackson was in office, he did more to expand executive power than any of the previous occupants of the White House. He used armed troops to collect taxes, refused to enforce legislation and supreme court legislation, and hired and fired his staff based on support in elections. He was also the first president to regularly wield the presidential veto as a political tool. Was he a good president? Watch this video and draw your own conclusions.

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. One of Andrew Jackson's most lasting and memorable policies was that of Indian removal: https://www.commonlit.org/text....s/andrew-jackson-s-s

Be sure to make an effort to use them often in your school work, presentations, and everyday life. An expanded vocabulary will separate you from the average person, especially at the interview for a job.___________________________________________________________________________ ________________________ ABOUT ________________________________________ Complete K12 essentials Youtube channel and Complete K12 Essentials.com was created to offer parents and teachers an online augmentation or alternative when public schools are not available. The need for standard curriculum that can be delivered via the internet became obvious during the pandemic of 2020. Teachers and school districts were left to create lesson plans and somehow connect with the students with very little time. The challenge was to give each child a method to connect with teachers and class mates to simulate a natural learning environment. Although we are still building our library of video lessons, you can use our videos to create lesson plans, review standardized material, introduce building blocks and drills, as well as assigning tests and quizzes on limited videos, such as vocabulary. We are building videos that will serve all students from kindergarten through the 12th grade. Recently launched on June 21st, 2020 our goal is to provide videos that will serve as a resource for those teaching or those looking to cover important standardized curriculum. We believe that access to a solid foundation of knowledge should be available to everyone who chooses to seek it. Many offerings online lean on animation to capture a childโ€™s attention, which to a certain extent works, but they lose interest rapidly and the opportunities for learning are significantly reduced. This is especially true when the child has no obligation to retain the material or accountability to a teacher. Navigating through the material suitable for each grade level is a difficult task at best, so we have created the โ€œSAFE LEARNING PLACEโ€ logo and apply it to all of our videos to show you our dedication to providing good learning material that can be trusted across our whole channel. The curriculum will cover Math, Language Arts, Social Studies, Science, Technology, Music, Art, Health and Fitness, Foreign Languages, Life Skills, Career training, History and Law.

Since the beginning of civilization, humans have been inventing tools and weapons. From flint axe and spear heads in the Stone Age to nuclear weapons in modern times, mankind has continually tried to improve and build new weapons that would give them an advantage over their enemies on the battlefield. The introduction of firearms marked the beginning of the most exciting chapter in the history of weapons. During this period, there were a lot of guns that were to be iconic of their era. But, on the other hand, there were more than enough guns that carried the title of the worst contraptions in history. This is the story of five of the top worst guns.
