Like all electricity, static electricity flows at the speed of light, or 186,282 miles/second. The interactive simulation shows how like charges repel like charges and opposites attract. The user can choose either one or two balloons, a...

Every knows that opposites attract! Here's a presentation that uses this background knowledge to explain magnetic fields and forces. The resource also explains the shape of magnetic fields and how to determine the direction of forces.

Calling all spades, diamonds, hearts, and clubs! Four teams compete against one another to collect all 52 cards in a deck. Each team lines up on one side of the gym, opposite of the deck of cards. Each team member takes turns running to...

Have the class run continuously in the shape of an hourglass with the hourglass relay activity. Four lines stand in four opposite corners and run to respective lines making the shape of an hourglass. They high five the first person in...

Divvy up the class into equal groups. First person in line on each team runs to the opposite end of the gym, around the cone, and back to their line. They pass off the bean bag to the next person and sit at the end of the line.

Run like a lion! As the teacher calls out an animal, one person from each team runs to the cone at the opposite end of the gym like the animal that was called. Then run back and high-five the next person in line signaling them to go....

After separating the class into equal teams, the first player in each line runs to the opposite end of the gym to the fitness mat. Then, they do a certain number of reps of a certain exercise

When the chosen person yells "Face the wall!" everyone on the opposite end faces the wall while the tagger counts down from five and hides behind an exercise mat. When the tagger gets to zero, everyone runs across the gym to the other...

Partner up the class. Break up one set of partners and assign one as a chaser and the other as a flee'er. The flee'er runs around the gym away from the chaser. If the flee'er is tagged, then he become the chaser. If the flee'er...

Choose a person to be the stoplight. Have everyone else line up on the opposite side of the gym. If "green light" is called out, the players run toward the stoplight person until they hear "red light," which means stop. Anyone that does...

Begin the game by setting up the two opposite corners of the gym as hospitals, while assigning two taggers. Choose two people as ambulance drivers, and they will use the scooters as ambulance beds (scooters are connected with a mat on...

Split the class in half. Set up two cones on opposite ends of the gym, using the gym lines as boundaries. These are the jails. The object of the game is to tag another player that is "older" (not in age) than another. The "fresher" a...

Split the class into two groups—the meteors and the satellites—with the majority of the class being satellites. The inner circle in the gym is "inner space" while the court around it is "outer space." When satellites are in inner space...

In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...

Investigate how the equation y = -1/x relates to perpendicular lines. Pupils align an arrow using an interactive so it is perpendicular to a bow string. A set of challenge questions helps learners discover slopes of perpendicular...

It seems perpendicular lines have slopes which follow a specific rule. Scholars use an interactive to investigate this rule by moving a pair of lines on a coordinate plane. They find that perpendicular lines have slopes that are opposite...

Why does like dissolve like? While in many cases opposites attract, the same cannot be said for chemistry! Solution scholars take an up-close look at the dissolving process with a customizable interactive. The resource allows users to...

Polar opposites might not work together—but polar coordinates do! The interactive provides learners the opportunity to graph trigonometric and algebraic functions using polar coordinates. The program takes either individual data points...

Relationships are often the highest priority for teenagers, but they don't always have the maturity to navigate a healthy connection with peers or family members. A series of group activities prompt class members to interview their...

What's the opposite of multiplying binomials? Learners apply their previous knowledge of multiplying binomials using algebra tiles to factor trinomials. The lesson introduces factoring as a process that uses algebra tiles to...

For every action, there is an equal and opposite reaction. In the case of the blob, that reaction is a trip several feet in the air! Learners begin by watching the world-record blob jump. They then analyze the flight of the person using...

Scholars view comics from two different perspectives; one paints the Alfred Dreyfus as innocent, while the other portrays the exact opposite. They solve the mystery of what happened by analyzing the source, working in groups, and...

The greasers and Socs, both gangs in S.E. Hinton's The Outsiders, came from opposite sides of the tracks, yet seemed to live in two different worlds. Scholars answer comprehension questions, create alliterations, and work with...

Shall we agree to disagree? Scholars have the opportunity to choose a topic they feel is controversial in the world and express ideas about it. They complete essays that address the opposite views. In two other essays, they analyze a...
