If your math students are having a hard time with graphing and slopes, this video could be a great resource as they prepare for the SAT. Sal takes care in explaining his thought process, making sure where to note different strategies to...

Sal picks up the pace in this video, going through problems 1-7 on page 774 of The Official SAT Study Guide. Basic algebra, arithmetic, and geometry problems start out this section, allowing students to build up some steam before hitting...

Clarifying that speed matters more than rigor on the SAT, Sal takes care to show students the most efficient and easiest ways to solve various math problems. Those who get stuck on certain types of problems would benefit from his...

Continuing his SAT review session, Sal explores problems with slopes, linear equations, and congruent angles. He begins problem 10 (geometry) but finishes the problem in the next video.

Are you constantly having trouble with constant functions? Learn how to graph these types of functions by watching a helpful video. Viewers follow along as the narrator creates a table of values and plots the resulting points to graph...

Most teens like to sleep in as late as possible, so testing the fastest way to get to school sounds like a great idea. A presentation walks through how to identify the controls, independent variables, and dependent variables in setting...

Everyone knows that one twin is always older in a pair. But, could a twin be years older? A video from an extensive physics playlist explains Einstein's theory of special relativity. Topics include the speed of light, special versus...

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...

The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...

What is the difference between an arithematic sequence and a geometric sequence? In an arithematic sequence the constant ratio is added, and in a geometric sequence the constant ratio is multiplied. Watch this video and learn how to use...

Danny the penguin represents a constant and snow represents variables. This clip is wonderful for learners just starting to understand algebra. It is clear, provides concrete examples, and is totally cute. A great idea for expressing...

Middle schoolers examine the effects of variables. They view a video which introduces the concepts, take part in an internet-based activity, then engage in a hands-on activity which allows them to practice what they have been studying.

In this ideal gas law worksheet, young scholars solve eighteen problems using the ideal gas law to solve for moles of gases, temperature of gases, pressure of gases or volumes of gases.

Learners explore equations with constants, variables and with exponents. They identify and define variables, constants, exponents, expressions, and equations, as well as give an example of each. Your class will also draw their...

A great start to activate thinking about the scientific method, instruments, measurements, accuracy, constants and laws. Each slide describes important procedures and examples essential for the study of science.

Positioned inside the framework of linear and exponential functions, this lesson is more of an investigation into the effects of changing variables and constants inside an expression. The author takes familiar formulas, those for...

Writing a quadratic equation in standard form gives values for a, b, and c that can be used to find several pieces of information about the graph of the equation. Knowing a, b, and c-values allows one to find the axis of symmetry, the...

The instructor explains the product rule of inverse variation using the transitive property of equality.

In this math worksheet, learners find the solutions to the problems that apply the time-independent Schrödinger equation. They examine the relationship between the mass and energy.

In this chemistry worksheet, young scholars write two forms of the ideal gas law. Then they identify the size and units of the ideal gas law. Students also solve the equations for each ideal gas law.

Use this lesson in your algebra class to help high schoolers identify the coefficient in a variable expression. After the do this, they identify the constant in an expression, identify an algebraic term, and identify an algebraic...
