Most pupils learn quickly how to apply Newton's Second Law equation to calculate net force. However, many struggle to determine net force before calculating the value of an unknown force from a force diagram. As part of a larger series...

Drugs interact with the brain to alter moods, emotions, and behaviors by changing the brain's chemistry, perceptions, and interactions. The final lesson in the Pharmacology unit shows scholars experiments, has them complete four labs,...

The third of a four-part series on Pharmacology teaches scholars how drugs enter and exit the body, how they act inside the body, how they affect the brain, and more. Over the course of the unit, groups complete two labs and one...

What exactly goes into the medications people take every day? Scholars learn about the chemistry of medications in the second of a four-part series on Pharmacology. Over the course of two weeks, class members complete seven experiments,...

Learn about the study of medications, including those found in nature and those made synthetically. The first of four lessons in a series on pharmacology includes lectures, hands-on experiments, research, and more.

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...

Why are gym walls padded and cars required to have air bags? Scholars observe two similar situations, such as those listed above, with only one variable altered. They identify the different variable and determine how the variation...

Scholars quantitatively apply their knowledge relating impulse, force, and time in the collision of objects. Three progressive levels challenge pupils with different ways of analyzing these problems. They identify multiple collision...

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...

Physics formulas provide more interest than simple math equations thanks to an informative installment from the series on Newton's laws of motion. The formulas guide pupils' thinking about how varying a quantity affects the rest of the...

Pupils read a description of a physical situation and select the free-body diagram that best matches. As part of a series on applying Newton's Laws of Motion, scholars reinforce their skills applying forces and considering their relative...

A common complaint among physics scholars studying Newton's laws of motion concerns drawing free-body diagrams. To practice the required pre-requisite skills for free-body diagrams, individuals identify which forces act in specific...

Free-body diagrams display all forces acting on an object, helping scientists represent Newton's Laws of Motion. Scholars read a short description of motion and view the free-body diagram to begin the installment of a larger series on...

Scholars focus on associating balanced forces with at rest or constant velocity motion and unbalanced forces with acceleration or deceleration. Practice problems with immediate feedback allow for quick success in an installment of the...

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Parallel circuits often provide less of a challenge for teens than parallel parking. An installment of a series on parallel electric circuits requires learners to solve increasingly difficult  levels of calculations. Each level...

Better than some television series, parallel series circuits provide practice for calculations. Scholars work through a series of problems, each progressively more difficult. They apply knowledge of voltage calculations, resistors, and...

Join the resistance—Ohm! Scholars apply Ohm's Law to problems of increasing difficulty as part of a series on electric circuits. The lesson begins with simply doubling and tripling voltage or resistance. It ends with having pupils solve...

Never underestimate potential—electric or your own. Scholars apply a color scheme based on the changes in electric potential as part of a series on electric circuits. They consider splitting wires, light bulb placement, and voltage as...

Resistance is not futile ... it is voltage divided by current. Scholars apply their knowledge to a series of ranking puzzles. First, they consider wires of varying lengths and then wires of varying cross-sectional areas. Finally, they...

Pupils focus on the flow of electricity as they work through three sections of questions as part of a series of lessons on electric circuits. The activities cover the fundamentals, case studies, and law breakers. Learners use conceptual...

Scholars apply their understanding of circuits and electric pathways to many simulations. They move through three different activities and 18 questions, receiving immediate feedback after each answer. The lesson is part of a larger...

Scholars demonstrate understanding of kinematic graphs through matching dot graphs to position time graphs, dot graphs to velocity graphs, and a mixture of the two. If users feel stuck or confused, a Help Me! button offers an explanation...

Three sections review the key skills covered in a series on dimensional kinematics. The first covers the difference between distance and displacement. The second addresses the relationship between velocity and slope. The third includes...
