Go the distance in learning about distance, rate, and time. Young mathematicians use an interactive to investigate the relationship between distance, rate, and time. A set of challenge questions assesses understanding of these...

What is the fastest way to get from point A to point B if you are going through two different mediums, such as air then water? Scholars explore the way light travels through air, water, acrylic, glass, and diamond as they answer this...

Time is on your side. Scholars plot three points on number lines with different time units to represent the time it takes three people to bake pies. They determine the fastest baker and the difference in times between the bakers.

A timely resource illustrates the effects of the passing years on sedimentary rock formation! Young geologists discover just how long it takes to create shale, slate, and other sedimentary rocks. The interactive also shows...

Change is coming — but how much? Geology pupils discover the transformation of metamorphic rock using a well-rounded interactive. Topics include the effects of pressure and temperature on metamorphic rock, how time factors into the...

If your pupils think relative velocity is the velocity at which you can run away from your relatives, they need this simulation. Two bikers want to meet at a specific time. Scholars alter the velocity of one rider to arrange the...

Why is that shadow getting longer? Determine the changes in the length of a shadow as the sun changes position in the sky. Individuals use an interactive to calculate the length of a shadow at different times during the day via the...

What time is it when the arc length is pi? An interactive displays the measure of the angle created between the hour and minute hand of a clock. Pupils can set the clock to different hours and calculate the arc length based upon the radius.

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...

Pupils use an interactive clock to set specific times. They apply math to an everyday task as they determine the measure of the angle formed by the hands in degrees and in radians. 

Before iPhones and calendars, how did humans determine the seasons of the year? Middle school scientists discover how to use shadows to determine the time of year in an enlightening interactive. Pupils manipulate the sun and examine the...

Show budding mathematicians how to model a diminishing bacteria colony two ways—graphically and algebraically. Using the coordinate axis, pupils create a graph to represent the decay of a bacteria colony. They determine the number of...

Take the tediousness out of graphing. Using the interactive tool, learners can efficiently create a line graph from a set of data. They then use the graph to answer questions about specific trends in the data.

We'd all like to see our money double. An interactive shows how an initial investment of $1,000 will increase using a constant rate of return. Scholars answer a set of challenge questions based on the situation.

Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

The sun can tell us what time it is with a sun dial, but can the moon do the same? Scholars play with a simulation of the phases of the moon. They control the type of moon and time of day in order to see when the sun is up and when the...

Swimmers improve their times by understanding the physics of their sport. As a swimmer moves through the water, the efficiency of motion affects the resulting velocity. Through an interactive simulation, pupils change the level of motion...

Can you time the speed of your car perfectly so you only hit green lights? The challenge in the simulation is to alter the timing of the lights or the speed of the car in order to do just that. Scholars learn about angular speed as they...

What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...

Determine the location of the pillars in time. Given a table of values for two parametric equations, pupils complete the table to determine the location and time it takes to build the pillars. Learners plot the points representing...
