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...

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

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...

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...

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...

Young meteorologists explore different aspects of the weather while learning about measurement devices. They build instruments and then set up a weather station outside and measure temperature, humidity, air pressure, wind speed, and...

Young scholars investigate which metal is best to use as storage material in hydrogen cars. In this chemistry lesson, students differentiate endothermic and exothermic reactions. They write a reflection paragraph about what they learned...

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?

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.

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.

"We Are Never Ever Getting Back Together" makes the perfect theme song for meiosis. The simulation encourages scholars to move the chromosomes and chromatids to properly illustrate the meiosis break up. Multiple-choice questions allow...

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.

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...

Students study energy sources to learn about fossil fuels and environmental concerns. In this energy sources lesson, students watch demonstrations for various energy examples. Students find hidden pennies, make a bar graph on their data,...

Ask learners about their personal writing habits, such as whether they keep a journal or a blog, or if they'd ever want to. Though this is not a fully developed lesson, you can use this article and question to provoke discussion and...

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...

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.

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.

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...

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...

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...

Students are focused on the big question: What makes a population grow and how could that growth stop? They use these concepts to help answer the big question: carry capacity, density dependent v. density, independent factors, predation...

Test your pupils' understanding of the scale from macro to atomic. While displaying images of different materials, learners identify what they would need to make that material visible. Their choices range from the human eye to an...
