Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

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.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

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 chemistry video tutorial highlights the difference between the bomb calorimeter and the coffee cup calorimeter. The bomb calorimeter works at constant volume and the coffee cup calorimeter works at constant pressure. The coffee cup calorimeter is useful for measuring the enthalpy changes that occur in an aqueous reaction since enthalpy is equivalent to the amount of heat energy transferred at constant pressure. The bomb calorimeter is useful for measuring the energy of combustion of a substance. It's not used to measure the enthalpy change however.

This chemistry video tutorial provides a basic introduction into the 4 states of matter such as solids, liquids, gases, and plasma. Solids have a definite shape and volume. Liquids have a definite volume but not a definite shape since they assume the shape of the container. Gases do not have a definite volume or shape. Solids and gases are fluid which mean they have the ability to flow. Plasma is an ionized gas that can conduct electricity. Solids and liquids have a relatively high density and gases have a low density.

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.

What’s the weather?

In today’s technology-laden world we can start the day by simply asking our digital assistants “What’s the weather going to be today?” But weather goes far deeper and can be far more interesting than just whether or not you are going to put on a jacket today. We are going to explore the fascinating world of weather and show fun ways you can interact with the weather every day!

Let’s start with what the weather is. Weather describes the conditions outside at any given time. This usually includes the temperature, if there are any clouds present and, the reason most of us check it, will there be any rain?
Let’s start with temperature. The temperature can tell you how hot or cold a day is going to be. In the United States we use the Fahrenheit scale. This scale is hundreds of years old and was based on human beings internal temperature being roughly 90 degrees fahrenheit. A thermometer is the device used to measure temperature. As technology improved and thermometers advanced we learned that a human body’s internal temperature is actually closer to 98 degrees fahrenheit than the 90 degrees that the scale was built off. The rest of the world, excepting Liberia and the Cayman Islands, uses the celsius scale. This scale is based on the freezing and boiling temperatures of water.
One of the questions students always ask me is “If I am 98 degrees then why does a 98 degree day feel so hot?” The answer to this question is all about the skin. When we take our temperature we usually put the thermometer in our mouth to get our internal body temperature. If you were to take the temperature of your skin it would be closer to 70 degrees. That is why we feel comfortable around that temperature and get hot or cold if the temperature goes above or below 70.
Our next big concern with weather is what is going on in the sky. Clouds can quickly turn a hot morning by the pool into a chilly afternoon. Clouds are made of evaporated water. As the sun heats oceans, lakes and even pools some of the water heats up enough to evaporate. This evaporation is what causes rain puddles to disappear when the sun comes out. The water warms and rises into the air until it reaches the colder parts of our sky. When the water cools down it condenses or sticks together, just like on a cold mirror in the bathroom after you take a hot shower. As the water sticks together it can form all kinds of different clouds. If enough of this water sticks together it can become too heavy and fall back down to earth.
Any water coming out of the sky is called precipitation. Precipitation can come in many forms. One of the most common forms is rain. As the tiny drops of water in clouds collect they will form raindrops, these drops fall through the cloud picking up more and more water on their way down. Sometimes raindrops can be small and misty, other times the drops can be huge and hit with a splash. If the temperature is cold enough these raindrops can freeze on their way down causing freezing rain, sleet and hail. If the cloud is cold enough the water freezes into ice crystals which fall as snow.
How can we interact with the weather? Grab a thermometer and head outside. Start by trying to guess what the temperature is before checking the thermometer. Set the thermometer down in a sunny spot and a shady spot. How do the temperatures differ when they're in the sun?
Make your own predictions. Head outside in the morning, look at the sky and guess or measure the temperature. What do you think the weather is going to be? Will there be rain, or is it going to be sunny all day? Write your predictions down and check to see if you were correct later on. Pretty soon you will be predicting the weather like a true meteorologist. (Scientist who studies the weather, not meteors.)
You can also build a rain gauge. A graduated cylinder works perfect but a cylindrical cup will work just fine. Put out your rain gauge before the rain and then measure how much rain fell by putting a ruler in the cup after. The number of inches of water in your cup is the number of inches of rain that fell during the storm. Did you know every 1 inch of rain would be 1 foot of snow if the weather was cold enough?
Weather is also not a local occurrence. A rainstorm in your area most likely formed hundreds or thousands of miles away. Many of these storms, like hurricanes, follow predictable paths. Using sites like ventusky.com you can track these storms as they begin forming hundreds of miles out in the ocean. You can also get a more global look at weather patterns.
We make a lot of decisions based on the weather. Most students just look at the weather as something that happens without spending a lot of time really thinking about what causes rain or where snow storms come from. Take some time with your student to observe, predict and even measure your local weather.

Learn to tell time on a clock that has three hands. The hands represent the hour, minute, and seconds.
There are 24 hours in a day
60 minutes in an hour
60 seconds in a minute

Use these 5 steps in order to make reading time easy
Step 1 start at the small hand look where the hour hand is pointing and write this number down.
Step 2 Draw two dots
Step 3 Read the large hand
Step 4 Draw two dots
Step 5 Read the skinny hand the seconds

Learn how to find the area of a circle.The area of a circle uses the formula is pi times radius squared.

Kingdom Mollusca Learn about snails, slugs, squid, and cuttlefish and several other invertebrates found in the phylum Mollusca. Animals in this phylum have soft bodies, many have a shell, a mantle, and a nervous system.
Some common members include snails, slugs, scallops, oysters, octopus, squid, nautilus, and cuttlefish.
