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...

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...

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...

Ninth graders investigate motion. In this science instructional 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 lesson, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.

Students 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...

Young scholars 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...

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,...

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

Students 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 and are...
