The human body is an amazing thing! Explore the body with your high school class as they investigate each system in detail. They learn components of each organ system and disease processes that can negatively affect general health and...

You'll be over the moon about this resource. Scholars draw a line representing the weight of an object on the moon based on its mass. Consideration of the constant of proportionality allows them to see relationships between weight of an...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Leaves fall off the tree in the autumn, but why do they change colors? The interactive covers the role of chlorophyll and photosynthesis. It also explains both carotenoids and anthocyanins.

Theory or Law? You decide. And so will your class members, in an insightful interactive. Young scientists divide common scientific principles or statements between the two groups, then dig deeper in understanding the functions of...

Einstein once said "A person who never made a mistake never tried anything new." Enlist his help in teaching young learners the importance of looking for mistakes in hypotheses. An interactive coaches pupils in the falsifiability of...

To what degree do learners understand coordinates? Get them some practice in Yosemite National Park in a simple, fun interactive. Pupils explore a map and locate coordinates of popular sights within the park, then answer questions...

Maps are great for helping you get where you're going, but what does that place actually look like? Geology scholars compare and contrast the features of topographical and geologic maps using an interactive lesson. The resource describes...

It turns out there's a lot more to heading south for the winter for migratory birds! Study the Coriolis Effect with a fun, hands-on teaching tool. Pupils take to the skies as a small red bird bound for the tropics from his frosty home at...

Get crazy for crystals! Junior geologists learn the secrets of crystal formation through lecture, reading, and examples. Other topics include common ionic compounds found in fresh and salt water, the effects of location on forming...

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...

Geology scholars test their rock identification skills in an interactive that examines the rock cycle from the three main nodes of rocks. Other topics include visual clues to rock identity and the conditions needed to make rocks change...

Transcription means a written copy but how can DNA write a message? The video explains transcription and translation as they relate to DNA and RNA. Then in the interactive, scholars practice base pairing and answer analysis...

Some molecules move through a membrane with diffusion while others require protein channels. The video and interactive discuss both types of passive transport. Challenge questions allow scholars to demonstrate their understanding.

How much negative feedback does a body get daily? The interactive walks through one negative feedback loop, increasing body temperature. Then it challenges scholars to relate this to mechanical feedback loops and disorders that prevent...

Can human activity influence the colors of moths? The simulation explains how pollution changed the color of tree bark, which led to the survival of a different variation of moths. It also discusses the shift back as air quality improves.

If any of the limiting factors in an environment change, both animal and plant populations also change. The video explains two different models of growth and the impact of limiting factors. It highlights the carrying capacity of an...

One of the few organisms that are classified by the environment in which they live include archaea. The video describes the phylogeny of the group and their major characteristics. It details how they reproduce and discusses the diversity...

Which has the higher IQ, latitude or longitude? Longitude because it has 360 degrees! The interactive introduces the way latitude is measured and why it can never have more than 90 degrees. A handful of challenge questions encourage...

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...

Mathematicians answer five questions about percents, ratios, and proportions with help from an interactive graduated cylinder. Question types include multiple-choice, fill-in-the-blank, and discussion. 

Have your class use the engineering design process to program a vacuum robot. Using computer engineering concepts, teams program an automatic floor cleaner to traverse designated patterns. 

Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.
