Students solve problems involving electric charges and force. In this physics lesson, student solve word problems using addition and subtraction of vectors. They identify the direction represented by a vector as it relates to an electric...

Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

Investigate invisible forces. Young engineers design a setup that changes the direction of a steel ball using a magnetic force. The purpose of the setup is to model the gravitational pull of spacecraft by planetary bodies.

Are brighter stars actually brighter? Turns out they are probably just closer! A presentation compares features of stars to our favorite star, the sun. In addition, solar lovers learn to classify stars based on their masses,...

Go around and around in your physics class with this presentation on circular motion. Diagrams bring the definition to life. Formulas for angular acceleration, centripetal force, gravitation, and potential in a radial field are given....

Students identify the different requirements for photosynthesis to take place. In this space science lesson, students simulate conditions in Saturn to investigate if photosynthesis is possible there. They use data and observations...

Students calculate the strength of gravitational force exerted on the moon by the sun and earth. In this orbital lesson students view a demonstration to see the gravitational forces between bodies.

Students explore how Newton tied together the gravity observed on Earth and the motion of the Moon. They apply an earlier instructional activity about centripetal forces.

Having a good working knowledge of math vocabulary is especially important for geometry learners. Here are 119 pages worth of wonderfully constructed definitions, constructions, formulas, properties, theorems, and postulates. This is a...

Graph A goes with equation C, but table B. The short assessment task requires class members to match graphs with their corresponding tables, equations, and verbalized rules. Pupils then provide explanations on the process they used to...

Study explore the motion of maple seeds and design experiments to explain their spinning flight patterns. They make observations, explain ideas of motion, use models, analyze previous reports and experiments, identify relevant factors...

In this math instructional activity, students create and solve equations with the help of Algebra Tiles. Then they apply formulas for geometry to find the perimeter of a polygon.

Learners create a 3D vector field map of an electric field. In this physics lesson, students measure the voltage inside an aquarium with water. They present their findings and map to class..

Students practice calculating the moment of inertia when discussing a skater and the position in which it is best to spin. After class discussion, students practice calculating inertia on their own.

Describes the logic behind the development of Newton's law of universal gravitation. Beginning with Johannes Kepler and his three laws of planetary motion, content walks the reader through Newton's thought process and development of this...

Learn about how the intensity of light is governed by the inverse-square law with this activity. Activity has you experimenting to find that the intensity of light decreases as the inverse square of the distance.

Electrical force between two electrically charged objects is inversely related to the distance between the two objects. Investigate why this becomes the inverse square law of physics. Engage in the Coulomb's Law interactive and check...

Illustrated examples of the Inverse Square Law with interactive opportunities to practice the problems.

Through illustrated examples and interactive practice, students explore Newton's ability to relate the cause for heavenly motion (the orbit of the moon about the earth) to the cause for Earthly motion (the falling of an apple to the...

States the equation of Newton's law of universal gravitation. States the value of G and uses the equation to solve problems.

You've probably heard that compact fluorescent light bulbs are more efficient than incandescent bulbs. More of the electricity they use goes into producing light, and less into producing heat than with incandescent bulbs. How much more...

An equation for the law of universal gravitation is stated. The weight equation (W=m*g) is related to the law. An interactive JavaScript form allows the user to practice determining the force of gravity and the acceleration of gravity...

This tutorial helps students learn about Radiographic Inspection through the concept of Newton's Inverse Square Law.

From the Exploratorium Museum. Includes an interactive feature in which a visitor enters their weight on earth and has their weight on other planets computed and displayed. Discusses the distinction between mass and weight and describes...
