Projectile Motion
Have you ever wanted to shoot someone out of a canon? This simulation gives you that chance! In addition to a human, you can shoot a car, a piano, a cannon ball, and many other items. Scholars set the angle, initial speed, mass, air...

Ohm's Law
Why did Mr. Ohm marry Mrs. Ohm? He couldn't resistor. An electrifying simulation allows scholars to control both voltage and resistance in order to see the current change. The formula is displayed and as you increase one variable, it...

My Solar System
Orbit diagrams appear to be a work of mathematical art. The simulation helps scholars build their own systems of planets, stars, moons, etc., to observe their orbits. By altering their positions, velocities, and masses, a variety of...
PHET
Hooke's Law
Everything from pens to cars use springs — some are just on a larger scale! An interactive simulation encourages pupils to stretch and compress springs while observing the changes to force, displacement, and potential energy. Then they...
PHET
Masses and Springs
Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...

Electric Field of Dreams
What is the largest electric field in the world? The world itself! This explains why you use a magnetic compass to determine direction. During the simulation, scholars add charges to their electric field to see how the field reacts. An...

Energy Skate Park
Apply the concepts of conservation of energy to a skater to introduce a fun way the concepts apply to real life. Scholars build tracks, ramps, and jumps then analyze the various types of energy and friction. For an added challenge,...
PHET
Forces and Motion
The average American will move 12 times, which results in a lot of moving furniture! Class members consider the forces required to move objects with a creative simulation that opens with the forces required to push a filing cabinet....

Order of Operations Task Cards (2)
Young mathematicians use their PEMDAS knowledge to solve 20 different task cards. They evaluate expressions to find the answer of multiplication, division, addition, subtraction, and exponential problems. Then, they record their answers...

Inaugural Words: 1789 to the Present
One of the reasons presidential inaugural speeches are so inspiring is the way word choice reflects the historical context of the time. An interactive timeline invites learners to click on their president of choice and view the most...

The Greenhouse Effect
How do greenhouse gases impact temperature? Have your classes use the interactive software to explore different concentrations of greenhouse gases and their effect on climate. Learners can recreate different atmospheric concentrations...
PhET
Wave on a String
The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Balancing Chemical Equations
Just like the old saying goes, "What goes in must come out." This simulation allows pupils to balance chemical equations. The introduction gives three examples before scholars switch to game mode, pick their level, and continue to...

A Catalyst and the Rate of Reaction
More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...

Temperature and the Rate of a Chemical Reaction
Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

Forming a Precipitate
Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity, scholars...

Controlling the Amount of Products in a Chemical Reaction
Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class members experiment to...

Temperature Affects Density
Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

Density of Water
We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.

Changing State: Melting
Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

Changing State: Freezing
There are five types of frost: ground frost, air frost, hoar frost, glaze, and rime. Scholars mix ice and salt in a metal container to observe frost forming on the outside of the can. Animations and videos enhance the learning.
