The Night Before Kindergarten
by Natasha Wing
Illustrated by Julie Durrell
Read by Let's Read Stories

'Twas the night before kindergarten,
and as they prepared,
kids were excited,
and a little bit scared.

It's the first day of school! Join the kids as they prepare for kindergarten, packing school supplies, posing for pictures, and the hardest part of all--saying goodbye to Mom and Dad. But maybe it won't be so hard once they discover just how much fun kindergarten really is! Colorful illustrations illuminate this uplifting takeoff on the classic Christmas poem.

Back to school books read aloud by children can help kids develop literacy skills and confidence as they start school. Let's Read Stories has lots of books for children and kindergarteners to listen and learn pronunciation, abcs, 123s, sight words, and more. Thanks for watching!

You may have noticed that the internet is terrible at religious discourse. Well, this is not a new phenomenon. In the early 16th century, the Roman Catholic church dominated Christianity in Europe, and the institution was starting to show some cracks. Tensions mounted and protests grew, and eventually, the Protestant Reformation happened. Martin Luther nailed his 95 Theses to the church door in Wittenberg, but the Reformation doesn't exactly begin with Luther, and it certainly doesn't end with him. Today, we're looking at how and why the Catholic church in Europe split, first into two sects, and eventually into a LOT of sects.

Today we’re going to talk about urban planning — which is the design and regulation of space within urban areas. Urban planning helps weave together economic, social, and environmental goals within a region from work, to play, and living, and unsurprisingly, has a tremendous influence on people’s lives! So today, we’re going to discuss some models we’ve used to describe existing cities such as the Latin American Model, take a look at a planned city and the capital of Brazil, Brasília, and look at the impacts of the US highway system and redlining on minority Americans starting in the 1960s.

Today we're learning about the Transatlantic Slave Trade, which brought millions of captive Africans to the Americas between the 16th and 19th centuries, with the largest number of people trafficked between 1700 and 1808. We'll look at the ships and crews that brought enslaved people across the ocean via what was known as the Middle Passage and explore the horrific conditions that these captives endured.

This week, Stan teaches you about patents. It turns out, they're patently complicated! So, patents have some similarities to copyright, in that they grant a limited monopoly to people who invent things. The key difference between patents and copyright is that patents are for THINGS. Copyright is for an idea. So, if you've come up with a great new invention, like for example, a condiment gun, you should get a patent. We'll also talk about some of the limitations and problems of patents, including patent trolls

And now we return to blood vessels. In this episode, we start discussing what blood pressure is, how it can become "high", and what that means for our health. One of the more interesting points is that your body has ways of dealing with high blood pressure, but they're not ways we want our bodies to operate on a full-time basis. And why can't we butter our bacon? WHY!?!?!

Educational video for children that talks about characteristics of various animals. The lion is a vertebrate animal, that is, it has an internal skeleton. It is a mammal and a carnivore, so it eats other animals that live in the same habitat, the savanna. The penguin is a vertebrate, so it has an internal skeleton as well. It is a flightless bird and feeds on small fish, crustaceans or plankton. The turtle is a vertebrate so it too has an internal skeleton. It is a member of the reptile group. Some turtles are herbivorous, but others are omnivorous, that is, in addition to plants, they also consume animals such as slugs or snails. Turtles live in forests, deserts, lakes and even the sea. Bees are invertebrates, which means they have no internal skeleton. They are arthropod insects and are herbivorous, since their main food is pollen and nectar from flowers, and the honey they make themselves. The elephant is a vertebrate with an internal skeleton. It is a mammal and a herbivore; it eats roots, leaves and the bark of some trees. Elephants live in tropical rainforests and savannas and they are huge. Frogs are vertebrate animals and belong to the amphibian group. There are many types of frogs, but they are all carnivorous; they eat crickets, butterflies, and flies among other things. They live in damp places near bodies of water like rivers, lakes, reservoirs, or even in large puddles. Giraffes are vertebrates, meaning they have an internal skeleton. It is a mammal and a herbivore, mainly eating leaves from the trees it finds in its habitat, the savanna. The shark is a vertebrate and belongs to the fish group. Sharks are carnivorous and their size depends greatly on the species. Jellyfish are invertebrate animals belonging to the coelenterate group. They are carnivorous and feed on plankton, crustaceans, fish eggs and larvae. The spider is an invertebrate and it is an arachnid arthropod. Spiders are carnivores and their size depends greatly on the species. Spiders can be found in all habitats. Butterflies are invertebrates and belong to the insect group. Ninety-nine percent of butterfly species are herbivorous and feed on leaves and nectar. Tigers are mammalian vertebrate animals. They are carnivores, and can be found in the savanna, rainforests and grasslands. Ducks are vertebrate animals belonging to the bird group. They are omnivores because they eat plants, seeds, insects and small fish. They live in damp areas such as rivers, swamps or ponds. Crocodiles are vertebrate animals belonging to the reptile group. They are carnivores and their size depends on the species. They live in rivers, lakes and wetlands. Dogs are vertebrates belonging to the mammal group. Their diet is omnivorous, that is, they eat both meat and vegetables. Their size depends on the breed. They are domestic animals, which means they live together with humans. The zebra is a vertebrate animal, belonging to the mammal group. Their diet is herbivorous, as they eat mainly grass, but also bushes, branches, leaves and bark. They can be found in the savanna and the desert.

This video is a very useful and interesting resource for children. It is perfect for teaching about animals and some of their characteristics. It is an excellent video for primary and preschool education.

👉 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.

We learn how to solve exponential equations in which one side is a fraction. We use the power of -1, to get rid of the fraction and to then solve the equation in the usual way, by writing both sides of the equation as a power of the same base. The method is explained in detail by working through 3 examples.
