In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

Educational Videos and songs for Kids. In this video we’re going to learn about the birds.

They are so diverse, and there are so many colors and shapes, it's fun to learn about them. For example, this tiny little hummingbird doesn’t look anything like this huge ostrich. And these penguins don’t look much like this peacock with its large fan-shaped tail. Well, they may not look alike, but they’re all birds, and have many things in common.
Birds are oviparous... which as you know, means that they reproduce by laying eggs. The females lay the eggs in nests, in the rocks... or on the ground... And with the heat of their bodies, they incubate the eggs until the little chicks hatch.
Birds don’t have teeth, they have beaks or bills... And these can be very different, depending on what that species of bird feeds on.
They breathe with their lungs, that are connected to... bags full of air... called air sacs... and these help birds to fly. Also, nature, which is very clever, has made their bones hollow, so they weigh very little, and because of this it’s much easier for them to fly.
The skin of birds is covered with feathers: these protect them from the cold and heat. Birds have four limbs, the back ones are legs... and the front ones are wings. Together, the wings and feathers are essential for them to be able to fly... and in some cases... so they can swim.
Birds are terrestrial and most of them can fly. Can you think of any birds that can’t fly? That’s right!!! Penguins and ostriches are two species of birds that cannot fly.
Birds have four types of feathers: those that cover the whole body; flight feathers in the wings that help them to fly; down feathers, which cover the chest and belly and maintain the body at a constant temperature; and tail feathers that help guide the birds’ body like a rudder on a boat.
Birds can be classified into several groups, according to what they eat: herbivores feed on plants and grasses – their beaks are short and strong, and can crush seeds and grains. When they only eat grains, they are called granivores.
Carnivorous birds hunt and eat other animals, using their strong, curved beaks. Within the group of carnivores there are insectivores, that only eat insects, and piscivores that only feed on fish. These birds have pointed beaks that are long and sharp to help them catch the fish. Remember - birds that eat fish are called piscivorous.
The last group - omnivorous birds - includes pigeons and hens, and they eat almost anything.
So remember: birds are oviparous, which means they reproduce by laying eggs; their mouths are beaks or bills and they breathe with their lungs; their skin is covered with feathers; and depending on the food they eat, they can be herbivorous... carnivorous... or omnivorous.
 So, now you know a lot more about birds.

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

This physics video tutorial explains how to solve complex DC circuits using kirchoff's law. Kirchoff's current law or junction rule states that the total current entering a junction is equal to the total current leaving the junction. Kirchoff's voltage law or loop rule states that the sum of all the voltages around a loop must add to zero. You need to be able to distinguish a voltage drop from a voltage lift. In addition, you need to be familiar with ohm's law when dealing with loop rule using kirchoff's law. This video contains plenty of examples and practice problems on KCl & KVl circuit analysis.

Grade 7th on Khan Academy: 7th grade takes much of what you learned in 6th grade to an entirely new level. In particular, you'll now learn to do everything with negative numbers (we're talking everything--adding, subtracting, multiplying, dividing, fractions, decimals... everything!). You'll also take your algebraic skills to new heights by tackling two-step equations. 7th grade is also when you start thinking about probability (which is super important for realizing that casinos and lotteries are really just ways of taking money away from people who don't know probability) and dig deeper into the world of data and statistics. Onward! (Content was selected for this grade level based on a typical curriculum in the United States.)

Why are timed math drills bad for kids? And how do timed math drills promote math anxiety?

Let's explore the research of Stanford Professor Jo Boaler, the author of Mathematical Mindsets, concerning why timed math tests amplify math anxiety and turn students, especially girls, away from math. To reform math education, we need to shift the focus to a growth mindset for math and onto achieving deep mathematical understanding.

Jo Boaler: Stanford researcher, professor of math education and author of the acclaimed book, Mathematical Mindsets.

Math anxiety has now been recorded in students as young as five, and timed tests are a major cause of this debilitating, often lifelong condition.

Timed tests evoke such strong emotions that students often come to believe that being fast with math facts is the essence of mathematics.

This misguided emphasis on speed and memorization has resulted in high numbers of students dropping out of mathematics.

Brain research shows us that under the stress of time pressure, working memory can become blocked, leaving students unable to retrieve what they already know.

The blocking of the working memory and associated anxiety is particularly common among higher-achieving students and girls.

When schools make learning math an anxiety-provoking experience, we turn students away.

The best way to learn math facts is to through mathematical activities that focus understanding number relationships.

This authentic understanding is best achieved through taking the time to think deeply about number strategies. which takes time.

Yet, many people believe that mathematics is only about calculating -- and that the best mathematics thinkers are those who can calculate the fastest.

In truth, skilled mathematicians are often slow with math, because they take the time to think carefully and deeply about mathematics.

We need our students to become powerful thinkers
who can make connections, think logically, and solve complex problems.

To achieve this goal, we must shift the focus of math education away rapid calculation and towards deep mathematical thinking and understanding

This movement in education reform is gaining momentum and your input helps. Please join the conversation and share your thoughts in the comments.

Our Mission: MashUp Math is our creative solution to reviving students' passion and interest for learning mathematics. As young educators, we know that all students learn math differently and that a one-size-fits-all approach is simply ineffective. The idea that the ability to understand mathematics is reserved for a select few did not sit well with us.

In addition to sharing free teacher resources (which are teacher created resources) in the form of teacher worksheets, we share new YouTube math videos every week that help math teachers and students to better understand mathematics and the common core. Our lessons can be aligned with the common core standards for common core math and are immensely popular with flipped learning educators and anyone experimenting with flipped classroom learning.

As educators, we know what it takes to be a super math teacher and that we can’t always do it alone. In addition to our cool math videos, we share articles, blogs, inspirational quotes, teacher math worksheets, and math worksheets.

Many of our users serve as a special education teacher and use our cool videos to support their special education students with special needs. Our free online math lessons are also high adaptable to your homeschool curriculum and should be added to your list of free homeschool resources.
