Local winds are winds that do not blow for great distances. In this video, I cover two major types, sea and land and mountain and valley winds. These local winds occur because the land and sea heat up and cool at different temperatures and this produces wind due to low and high-pressure areas.

How are plant cells and animal cells similar and different? There is a great variety and plants and animals found on earth. If you look at a plant cell and an animal cell you will see they have similarities and difference.
Let’s first focus on how they are similar.
They are both considered eukaryotic cells because they both contain a nucleus and membrane bound organelles.
They have many of the same organelles, they both contain a rough and smooth er
Golgi body, mitochondria they both have ribosomes which create proteins. Technically ribosomes are not organelles because they are not membrane bound
In addition, animal and plant cells contain a cytoskeleton and cytoplasm,
Both plant and animal cells contain a cell membrane.
Next, let's focus on some of the differences.
A plant cell has a cell wall. The cell wall is a rigid outer covering of a plant cell that provides structure and protection.
Animal cells do not have a cell wall.
A plant cell has chloroplasts. Chloroplasts are the location of photosynthesis which allows the plant to convert sunlight into sugar The mitochondria found in the plant cell then uses this sugar to create energy.
Plants have a large central vacuole compared to an animal cell that contains smaller vacuoles.
Plants cells do not have lysosomes and animal cells do have lysosomes.
Lysosomes help animals break down large molecules, old cell parts and sometimes large macromolecules that get past the cell membrane. The cell wall of a plant keep these large molecules out and plant cells have lytic vacuoles that perform a similar function of the lysosomes in animals.
Plant cells contain plastids and animals do not have plastids.
The plastids of plants take several forms. The following is a picture of several of the different plastids found in a plant.
Plants do not have centrosomes and animals do. Centrosomes are the microtubule organizing and construction center and help spindle fibers attach to the chromosomes during mitosis
So there you go Some of the similarities and difference of a plant and animal cell.

In which John Green teaches you about the election of 1860. As you may remember from last week, things were not great at this time in US history. The tensions between the North and South were rising, ultimately due to the single issue of slavery. The North wanted to abolish slavery, and the South wanted to continue with it. It seemed like a war was inevitable, and it turns out that it was. But first, the nation had to get through this election. You'll learn how the bloodshed in Kansas and the truly awful Kansas-Nebraska Act led directly to the decrease in popularity of Stephen Douglas, the splitting of the Democratic party, and the unlikely victory of a relatively inexperienced politician from Illinois, Abraham Lincoln. Lincoln's election would lead directly to the secession of several southern states, and thus to the Civil War. John will teach you about all this, plus Dred Scott, Roger Taney, and John Brown.

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. The Lincoln and Douglass debates of the 1850s fueled the argument over state's rights to decide on slavery and culminated when the two ran against one another in the Election of 1860: https://www.commonlit.org/text....s/the-election-of-18
In response to Lincoln's election, the South seceded from the Union and the Civil War began: https://www.commonlit.org/texts/the-south-secedes

The cytoplasm is the fluid found in cells.
Cytoplasm is found in eukaryotic and prokaryotic cells.
The fluid of cytoplasm is called cytosol. It is made up mainly of water
The organelles are found floating in this liquid along with many other items
You can almost think of the cytoplasm as a crowded swimming pool

Learn how to compare prices using unit rates. A unit rate tells you the cost of one. In order to compare different products, you can set up a unit rate. For example, which is the best buy, 9 can for 10 dollars or 15 cans for 13 dollars. You can create an equivalent fraction by dividing the numerator and denominator by the original denominator.

Rainforests for Kids explores the world of these dense, wet regions of the world. There are two kinds of rainforests—temperate and tropical. Despite covering less than 3% of the earth's surface, rainforests are home to more than half the world's animal species! They are essential to life on earth because they help maintain the fresh water supply and provide oxygen to the atmosphere. The world's climate depends on rainforests!

When you compare temperate and tropical rainforests, you will find a few differences. Tropical rainforests are closer to the equator and are thus a little warmer and have more rainfall. Temperate ones are found in cooler coastal areas. You can find a rainforest in every continent except for Antarctica. The largest rainforest in the world is the Amazon rainforest. Over 20% of the earth's oxygen is produced by the vegetation there!

There are four layers to a rainforest: emergent, canopy, understory, and forest floor. Different animals live in different layers. Small monkeys and snakes, for instance, live at the top. At the bottom, you would find leopards, elephants, and gorillas. The video describes some interesting facts about three cool animals in particular. Keep watching to learn more!

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

How to Play Chess - Animated Cartoon Series for Beginners | Kids Academy

Parents and teachers realize that school success and higher test scores lead to more opportunities in the secondary and college years. Chess for kids is a great way to improve higher-order thinking and problem-solving skills, and reading and math skills. Many US states and other countries around the world include chess in their curricula.

The best part about chess for kids is that all children can play at whatever level of ability they possess.
To learn chess for kids, simplified instruction is necessary. Video lessons are an effective and easy way to learn the basics of chess as the chess moves, strategies and techniques are viewed and learned in small chunks.

The learner has the option to play the video multiple times until mastery of the concept or skill is mastered. For instance, when a young player is working on how to learn chess, he or she discovers that in the opening moves of play it is important to control the center, develop your pieces and protect your king by castling.

As the child’s ability level increases, the player can begin to learn strategic moves for a quick check-mate as well as how to defend against these moves. The Scholar’s Mate is a 4-move check-mate strategy that many players learn when acquiring the basics of chess.

Viewing games that chess masters played in the past is another great way to learn the basics of chess. One such game is the Opera Game. In this game, chess master Paul Morphy demonstrates one of the best active attacking games of all time.
Teachers that encourage chess for kids in their classrooms see better results in the children’s academic performance and experience a positive classroom environment.

Parents that play the game with children at home enjoy quality time with their kids and know that playing chess helps children academically.
