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.

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.

You may have heard of people dancing to death, laughing to death or sitting on a throne to death, but there are many more surprising stories told to the Grim Reaper when the scythe is resting by the door.
What follows are what happens when you really want to stick it to your enemies for slowing your conquest of the Mediterranean, the consequences of leaving a nuclear reactor to inexperienced workers, the measures people will go to when they’re furious and hungry, and an unfortunate incident relating with an elephant-sized general.

Common Places in Your Community - City Vocabulary - Social Studies for Kids
Want to teach your kid some community places? Okay, let’s do it together. First, begin by explaining to your child what a community is.
A community is a place where we all live together. There are many places in this community where people go and spend some time either alone or with their friends and family. So now how can you make your kid familiar with the names of these places? Well, the most important thing is that you actually take your kid to these places so that he/she can see with their own eyes how this world works.
Then at home, of course, you can do some fun activities to keep the names in mind.
Using a search puzzle would be a great idea. Get or make an easy puzzle so that the child maintains an interest in it. Ask the kid to find out the names of the places mentioned in the puzzle. Use words like café, library, store, park, bank, school, etc. help the kid along and make sure that he/she finds all the words. This will help the kid increase his city vocabulary as well as recognize the common places in their community.
As long as the kid enjoys what he is doing, he learns fast and easy to make sure that the activity remains fun and interesting for the kid.

Symbiosis or Symbiotic Relationships are interactions between different species. In this video, Let's take a look at three types of symbiotic relationships.
Mutualism in which both win.
Commensalism in which one organism wins and the other is neutral.
Parasitism in which one wins and the other is harmed.

If you make a model of the distance of the planets on a large field you get an impression of how far away the planets and closest stars really are. In this model, 1 foot represented 15,500,000 miles.
The Earth is only 6 feet away but Pluto ends up being 236 feet away.
The closest star Alpha Centauri ends up being 305 miles away, Imagine that, 305 miles away on this scale when Neptune is less than 100 yards away from the sun. It is hard to imagine these kinds of distances.
Quadrilateral are 2D plane figures with four straight sides and angles. Learning the names of the different quadrilaterals can be challenging. I provide two methods, a quadrilateral chart, and a quadrilateral Venn diagram.
Each of these tools covers the common quadrilaterals and their properties
I cover the types of parallelograms and trapezoids.
Quadrilaterals cover include kite, trapezoid, parallelogram, rhombus, rectangle, and square.

Learn how to calculate work using the formula work = Force x Distance
0:00 Introduction to the work triangle formula
0:24 During a race a runner impacts the ground with a force of 200 Newtons. The runner runs a distance of 30 meters. How much work did the runner create?
1:18 If it takes 8 Newtons to move the sled 2 meters, how much work was created?
2:06 If it takes 500 joules of work to move the chair 10 meters. How much force is required?
2:54 What distance did the bike move if 600 Joules of work was used and 40 Newtons of work was applied to the bike?
