Matrices help solve systems of equations in chemistry, computer graphics, circuitry, probability, and more. The second lesson in a seven-part series focuses on using matrices to balance chemical equations. Pupils rely on the Law of...

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

How do law enforcement officers determine the strength of an explosion based on the movement of objects around the point of origin? Scholars inspect the relative mass and velocities of two cars before and after an explosion. They perform...

Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

How do police determine the speed of a car that has hit a stopped vehicle? Scholars determine the momentum of the car system both before and after a collision. They identify instances where the law of conservation of momentum appears to...

Students are introduced to the concept of Energy Conservation with the example of: Tony Hawk seems to defy the conservation of energy as he keeps reaching new heights on each pass on the halk-pipe. Actually, Tony is supplying the extra...

Students study Alfred Wegener's theory of continental drift and how the continents were connected in one large land mass called Pangaea. They examine plate tectonics and the theory that the earth's surface is composed of large moving...

Students discuss the conservation of momentum in a collision between two bumper cars. They are given the equation for momentum. Students then solve problems using the equation for momentum.

Here's a resource ideal for independent learners who need extra reinforcement or would like to work ahead. These textbook chapters and practice problems cover many basic physics concepts, starting with potential and kinetic energy and...

Students discuss the conservation of momentum in a collision between two bumper cars and an explosion between a bullet and the rifle's kickback, as well as collisions occurring in 2 dimensions and how they are all expressed mathematically.

Students are given the difintion of translational motion, which is the object in motion stays in motion. If you are in a car and the car stops, you keep moving. They then discuss rotational motion, which is a spinning object continues to...

Learners analyze the amount of space required to pack round objects. In this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

Ninth graders investigate motion. In this science activity, 9th graders conduct experiments on objects to analyze motion and speed. They define motion in everyday life.

Students investigate an accident and relate it to math. In this trigonometry instructional activity, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.

Students are introduced to rotational inertia with some example of objects that rotates: Throw a Frisbee acroos the field and it rotates as it moves. The same is true for a baseball and a football. The two motions, translational and...

Eighth graders analyze physical change in mass. In this chemistry lesson, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with elements,...

Students make a link between prediction and hypothesis in math and science. Based on data collected over one week, students evaluate the predictions of local weather forecasters, compare the predicted outcomes to the actual weather...

Students explore comparing and ordering volume of containers. They use the context of Goldilocks and the Three Bears to compare the volume of various containers by packing or pouring.

Eighth graders practice balancing chemical equations. In this chemistry lesson, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.

Middle schoolers practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio...
