Earth's Orbit Lesson

An extensive investigation of the Earth's climate changes awaits your environmental science classes. This top-notch presentation begins by looking at the history of Earth's climate and then predicts the impact on each major terrestrial...

Here is a challenging motion problem about two different length trains and how long it takes them to pass each other going in the same direction and opposite directions. At first glance, there doesnÕt seem to be enough information given...

Orbit diagrams appear to be a work of mathematical art. The simulation helps scholars build their own systems of planets, stars, moons, etc., to observe their orbits. By altering their positions, velocities, and masses, a variety of...

Let the class stars shine. Using four given linear equations, scholars create a graph of a star. The pupils use the interactive to graph the linear systems and determine the points of intersection. Through the activity, classmates...

Texas Instruments and Glencoe/McGraw-Hill have put together a full lesson to help you instruct your math class. Using the textbook, a TI-83 calculator, and attached the PDF learners will solve systems of equations and state decimal...

Secret codes are so much fun, and a great way to practice nearly any math skill. Let your class become code breakers as they investigate inverse matrices. They use TI-Nspire technology to solve systems of equations which help them crack...

Why does it take Pluto 90,000 days to orbit the sun, but it only takes Mercury 88 days? An interactive lesson helps pupils find a connection between the speed of orbit and distance a planet is from the sun. The simulation allows for...

How do you show change occurring in a non-moving object? Gain some insight into NGSS standard PS2C, Stability and Instability in Physical Systems, in a resource for educators. The narrator guides you through the core components...

Systematically combine shapes to arrive at one solution. The resource models a system of linear equations using colored shapes. Pupils follow rules to combine circles and squares to add the two equations together, resulting in one...

Section 9 of the 12 linked Saxon Math sections introduces the young algebrist to graphing periodic functions, creating graphs from quadratic roots, working with inequalities, and rational equations. Common among all the lessons is the...
