Land on the green with a fun resource. A short performance task asks pupils to consider the volume of containers that hold golf balls. They determine the percentage of empty space of the container for different numbers of golf balls.

John Muir may be a friend to the natural world, but as a short reading passage confirms, he is no friend to rattlesnakes. As young readers learn about Muir's encounters with the dangerous creatures, they answer four comprehension...

This isn't your typical basic lesson—it's more acidic! Learners use pH information to determine the hydroxide ion concentration of different substances and then use these values to analyze information. The calculations require...

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...

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...

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...

Scientists use many different kinematic representations of motion. Review each of them with the help of an engaging interactive that is part of a larger series on Newton's laws of motion. The resource provides three levels of challenge...

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...

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...

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...

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...

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....

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...

Many know that Native Americans were forced off their lands and moved west, but how did these people react? The Red Sticks faction of the Creek nation opted to defend themselves and their lands in a series of wars called the Eastern...

Here's an interactive with real potential ... potential energy, that is! Scholars analyze scenarios, then rank objects in order of greatest to least kinetic energy, potential energy, and speed. The interactive provides support materials,...

Physics class has its ups and downs ... especially when it involves energy concepts! Scholars analyze information to determine changes in kinetic and potential energy using an interactive resource. Realistic scenarios make connecting...

Current work lesson plan just not ... working? Add an engaging interactive that helps pupils explore positive and negative work relationships! Individuals assess situations to determine what type of work, if any, the resource describes....

Wrap up an engineering lesson with a worthwhile project. An engineering design task challenges groups to develop a package for a pharmaceutical company given constraints on the volume. Learners then create a presentation to highlight...

Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...

No vacuum cleaner? No problem, just build your own. Scholars apply knowledge of currents to build a model of either a vacuum clear, a hair dryer, or a toy car. While the class completes the activity, instructors consider gender...
