Amelia Earhart is the focus of a reading comprehension interactive practice. Scholars read an informational text; then answer 10 questions. 

A soccer-themed interactive challenges mathematicians to solve five questions involving percent equations. Question types include multiple-choice, fill in the blank, true or false and a discussion. A color-coded stadium with movable...

An interactive challenges mathematicians to round large numbers with help from a large scale that measures the weight of a blue whale. The practie's five questions include multiple-choice, fill-in-the-blank, true or false, and an open...

A six-question interactive tasks scholars with adding binary numbers one through eight. A tool acts as a visual aid to showcase the patterns made when working with base—2, digits zero and one. Question types include fill in the blank,...

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...

Does your blood type matter? The video explains the four main blood types and the importance of knowing blood types when performing transfusions. The interactive reviews the information with a quick graphic organizer and questions.

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...

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...

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...

Do predators look for different things in different seasons? The quick interactive shows how some species survive longer in one season than another based on the conditions. The challenge questions encourage pupils to demonstrate that...

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.

Can natural disasters alter natural selection? The interactive explores this concept with mice living through a forest fire. As the environment changes, the camouflage also changes. How does this one disaster impact future generations?

Sex-linked traits indicate a gene's location on a specific chromosome. Scholars learn about sex-linked traits and the specifics behind color blindness in the videos. Then they complete the online interactive to apply their knowledge...

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...

Eukaryotic cells go through a cycle of creation, reproduction, and death. The video choreographs the cell cycle to music from a popular movie. This prepares scholars to answer the questions in the online interactive.

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.

The 1590s saw the invention of the first compound microscope. Scholars learn about how microscopes work and how to properly focus one. The lesson stresses the science fields that use microscopes and the difference between electron...

Many fields of study require a specialty and a sub-specialty as you progress through your education. Scholars learn about six sub-specialties of life science. From botany to zoology, our knowledge of the world of living organisms expands...

Hyenas normally hunt alone, however scientists discovered that in Israel, hyenas hunt with wolf packs. When relationships develop between different species, we call it symbiosis. The videos teach about the three types of symbiosis and an...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

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...
