Friction leads to movement, heat, and melting on such a small scale most people don't notice. A short simulation permits scholars to observe the reaction between atoms as they move together.  The simulation applies the concept of...

Apply the principles of geology to a series of collaborative, hands-on class activities. Young earth scientists learn more about igneous, metamorphic, and sedentary rocks before classifying and weathering rocks that they find....

Explore how our chromosomes work to define human attributes. A complete unit presentation includes topics such as genetic disorders, blood typing, and Punnet squares. Learners answer questions throughout the presentation to apply the...

If you are at a sports match and the crowd starts two waves that are both headed toward you at the same time, what do you do? The simulation applies the concepts of constructive interference and destructive interference to that very...

When a car crashes into a wall, does it just stop or does it bounce or roll backwards? A simulation relates velocity, kinetic energy, momentum, and restitution to answer this question. Scholars apply their knowledge through...

Does Newton's First Law of Motion explain how to move a sled across ice? A simulation encourages scholars to decide if they should push, pull, or apply no force. Their decision moves a sled across the ice and to the home at the...

To show the magnitude and direction of all forces acting upon an object, scientists use a free body diagram. This simulation serves as an introduction to free body diagrams allowing scholars to build their own. Pupils select the proper...

Keep calm and use the force! Joey pulls a cart and scholars adjust the force required to control the movement. Through simulating different scenarios, participants learn about Newton's Third Law. It includes analysis questions throughout...

Have you ever tried following confusing or incomplete directions? In a hands-on experiment, partners give and follow directions to build a structure. Scholars apply their years of experience taking instructions to prove they know...

Does practice make perfect or just improvement? Scholars practice drawing a triangle on an Etch-A-Sketch. They learn about the part of the brain that controls sensory-motor integration and apply that to an analysis question.

How exactly does touch help us identify items? Learners test this question by feeling a coin without moving their fingers and trying to determine if it is heads or tails. They test their accuracy by rubbing their...

Which intermolecular force is the strongest? Scholars test the relative strength of London dispersion forces, dipole-dipole interactions, and induced dipoles using a simulator. The interactive allows learners to pull on paired molecules...

The 15th lesson in the series of 24 helps your classes understand the ppm (part per million) unit of measure. First, scholars experiment with food coloring to determine concentrations before applying their findings to calculate...

Experiment with optical resolution using an inquiry-based lesson plan. Young researchers calculate fellow classmates' optical resolutions. They apply the information to understand the inner workings of optical instruments.

Young chemists love it when colorful solid products appear in a reaction vessel! Scholars discover the products that form during halide ion tests through a hands-on activity. Users go online and apply chemistry knowledge and reasoning...

Amphoteric compounds act as both an acid and a base. Scholars apply their knowledge of the four oxide types while completing four puzzles. They match a sample of each type of oxide with the corresponding reaction.

Two men want drinks and the first orders H2O. The second man orders H2O too, but he dies. Scholars apply their knowledge of H2O2 and other everyday chemicals during the activity. They match chemical formulas to common chemical names in a...

It is best to avoid jokes about noble gases; they get no reaction. Scholars match the noble gases to their symbols and uses. Then they solve three gridlock puzzles reviewing the material while applying some simple logic.

Propanol is a common alcohol used in hand sanitizers. The many forms and uses of alcohols fill an intriguing lesson. Scholars apply logic to match alcohols, chemical structural formulas, oxidation products, and more in a series of puzzles.

A covalent bond yells at an ionic bond, "Didn't anyone teach you to share?" Four matching puzzles allow pupils to review covalent, ionic, and metallic bonding. They apply logic and problem solving to complete gridlocks including the...

How important is the tip of a new shoot on a growing plant? Individuals learn about the results of experiments on shoot tips and must interpret them. They apply previous learning and connect complex ideas through advanced analysis.

Sugar isn't good for you, but it's great for microbes. A simple experiment has pupils investigate the digestion of starch by microbes to produce sugars. They apply two bacterial cultures, an amylase solution, and distilled water on a...

Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...

It's a win-win situation: learn about enzymes and get clean clothes, too. Young scientists add enzymes to a dilution of laundry detergent. They apply them to stained fabrics to determine the effectiveness of the enzyme-filled detergents.
