How do contact lenses work? The simulation allows young scientists to explore focal length and lens type to see how and why contact lenses work. Pupils control the focal length for an eye and a lens, the type of lens, and the distance...

Sometimes the best view is from the farthest distance. Satellite imaging makes it possible to create altitude maps from far above the earth. A three-part activity has your young scientists play the role of the satellite and then use...

How does electricity travel through power lines? The simulation demonstrates the how changes in voltage and resistance are related to the distance between power polls and the thickness of the cable. Scholars control three variables in...

Spin through the trigonometric functions. Scholars determine the angle of rotation a snowboarding snowman makes at various distances in his jump. The class members then calculate the values of trigonometric functions for those angles.

Writing a number is all in the notation. The resource introduces the class to scientific notation. Pupils learn the process of taking a very large or small number in standard form and write it in scientific notation. To practice,...

Catch a great resource! Individuals use an interactive that allows them to move players on a baseball field. They calculate distances between players using the Law of Cosines.

How can we use vectors to determine a person's position when traveling? The simulation offers guided practice at determining the coordinates and the distance between coordinates on a map grid. It reinforces the importance of positive...

Tommy is trapped on an ice bridge and needs you to balance the charges so he doesn't fall into the icy water! Scholars apply Coulomb's Law, which relates to both the strength and the distance between charges. They work with these two...

Fire in the hole! Thrill your classes as they see what it's like to fire a cannon ball. Scholars practice aiming a cannon ball by altering first the firing angle, then the velocity, and finally both simultaneously. Can they discover the...

Climb every mountain, even one you create in an interactive. Individuals solve a problem involving slopes and distances of campsites on a mountain. Answering a set of challenge questions aids in the process.

Your class will be on top of their game when it comes to mid-ocean ridges! The second installment in a 13-part series focuses on the 65,000-km underwater ridge system that spans our globe. Junior oceanographers practice placing the...

The number of bicycle wheel turns is as good as any way to describe the distance from school to home. An interactive lets young mathematicians determine the number of city blocks a person bicycles. They use this information along with an...

Study diffraction patterns using CDs and DVDs! Scholars measure the diffraction patterns of a light wave as it hits a CD or DVD. Using the information, they can measure the distance between the tracks. 

Up, down, back, and forth. When you make a pendulum out of a spring, there's a lot to observe. Aspiring masters of motion examine the combined kinetic energies of spring and pendulum motion using a detailed interactive. Learners observe...

Hit a home run with a resource that is all fun and games. Learners apply an interactive to determine the horizontal component of the distance a baseball travels. They must consider vector projections for this task.

Hyperbolas—practice thinking outside of the box. Pupils alter the end behavior box to create various graphs of hyperbolas. They determine formulas to find the distance from the origin to the foci. Using that information, scholars...

What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.

Just in time for the start of the Winter 2018 Olympics, you can track the Olympic torch relay through the Republic of Korea. But there must be some math involved, right? Give learners a worksheet that prompts them to calculate the...

The shortest distance from point A to point B is a straight line—or is it? Young scholars determine the shortest route either along a circular path or through the center of the circle. Learners gain a unique perspective on arc length and...

Can you determine how far down a rock drops without visual clues? Viewers observe a clip from a movie testing vertical distance only based on sound. They must determine if it is safe to drop down themselves or if it is farther than their...

Sometimes you just need a taco. Young mathematicians investigate two different paths on a beach to get to a taco cart. Completion of the task requires finding distances using the Pythagorean Theorem and considering the different walking...

Often, the real-life experiences of soldiers gets lost back home when the war seems so far away. Scholars investigate the personal side of World War I in the trenches of Europe to complete a collaborative social studies activity. When...

Which is the best reflection of them all? Given four diagrams, pupils determine which one shows the most accurate reflection of a quadrilateral. Two images provide the distances of each vertex from the line of reflection, as well as the...

Do your young physicists get a little unbalanced when it comes to talking about torque? Scholars examine the effects of weight and distance on a balanced system with a simple interactive from the Rotation and Balance series. The resource...
