Ohm's Law: Voltage-Current-Resistance Relationship
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...
Physics Classroom
Know Your Potential
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...
Physics Classroom
Resistance Ranking Tasks
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...
Physics Classroom
Electric Current
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...
Physics Classroom
Light Bulb Anatomy
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...
Physics Classroom
Dots and Graphs
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...
Physics Classroom
Position-Time Graphs
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...

Position-Time Graphs - Conceptual Analysis
Increasingly, colleges and employers want applicants with strong conceptual analysis skills, so give them some practice! Applying these skills to position-time graphs encourages synthesis of knowledge. To complete an installment of a...
Physics Classroom
Match That Graph
Matchy-matchy no longer exclusively applies to fashion. Scholars work through three levels of practice matching position and velocity graphs. Part of a series covering dimensional kinematics, each question provides immediate feedback and...
Physics Classroom
Graph That Motion
Pupils apply their knowledge of the shape and slope of graphs to interpret the motion of an object. Three levels of difficulty provide plenty of practice with support thanks to the "Help Me!" button offered with each question.
Physics Classroom
Motion Diagrams
Scholars work through three activities building motion diagrams as part of a series exploring dimensional kinematics. Each activity has six descriptions requiring application of velocity vectors, acceleration vectors, and challenge...
Physics Classroom
Name That Motion
Pupils apply their understanding of motion to 11 practice problems as part of a series on dimensional kinematics. They view a dot diagram animation and read descriptions to identify which match. As a bonus, the interactive offers...
Physics Classroom
Acceleration
The acceleration rate of a flea jumping works out to 50 times faster than the acceleration rate of the space shuttle. Pupils apply knowledge of acceleration to dot diagrams, velocity-time tables, and word problems. They solve for...
Physics Classroom
Distance vs. Displacement
Home is where your displacement is zero. Scholars practice solving distance versus displacement problems of increasing difficulty. They begin with two stage motion and, by the wizard level, each problem has four stage motion to consider....

Sorting Seashells
Scientists use morphological, physiological, and molecular information to continually revise organism classification. Scholars observe and learn about 20 shells. Then, they work to sort and classify the shells, building a taxonomy based...
Physics Classroom
Trajectory - Angle Launched Projectiles
Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...
Physics Classroom
Up And Down
Many scholars confuse velocity and acceleration even after they correctly solve basic problems. Using an interactive, part of a series on vectors and projectiles, with immediate feedback focuses their attention on the up or down...
Physics Classroom
Vector Addition
Three levels of practice assure scholar mastery of vector addition. After inputting an incorrect answer, another problem replaces it so everyone finds success. The lesson works as one part of a series on vectors and projectiles.

Unit 2: DNA Analysis
Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...
Physics Classroom
Trajectory - Horizontally Launched Projectiles
Everyone enjoys projectiles, and predicting where they land helps with future hands-on labs. Incorporating gravity into horizontal trajectories through both conceptual and mathematical practice helps scholars understand real-life...
Physics Classroom
Free Fall
Scholars must understand freefall before they learn how objects like airplanes fly. They apply knowledge of velocity and acceleration to predict speed and direction as part of a larger series on vectors and projectiles.
Physics Classroom
Vector Direction
Scholars practice vector direction notation in multiple formats. After mastering each individually, they work to convert from one to another as one part in a series of lessons on vectors and projectiles.
