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...

"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.

Do words change or add meaning or interest to a work of art? The final lesson in a four-part series on the beautiful brain as a work of art focuses on art analysis. Scholars write a story about exploring art from the inside. Reflections...

We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Tommy is stuck in a dungeon and can only escape if you can discover the correct formula for velocity! Through trial and error, scholars enter the velocity required for Tommy to reach the elevator at the proper time. Then they extrapolate...

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...

How do we know how long ago a dinosaur lived or an ancient fire pit was used? Scholars learn about the application of carbon dating and half lives to discover things about the past. They adjust the amount of radioactive carbon in the...

Everything is made up of atoms, but what are atoms made up of? The simulation explores subatomic particles. It focuses on hadron, boson, and lepton groupings as scholars learn about quarks, neutrinos, gluons, and more.

What are some simple uses for an electromagnet? Scholars explore the electromagnetic circuitry in a doorbell through an interesting simulation. They control the core material, number of loops, amount of current, and strength in a spring....

Addiction is a big deal! Playing a game of cards helps learners understand the concept of addiction. Through their analysis, they examine the potential for addiction and how it varies for each individual.

Think like an engineer and an agricultural scientist over the course of 12 lessons in a STEM based unit. Young scientists take on the roles of animal physiologists, animal geneticists, agricultural engineers, animal nutritionists,...

What a great way to incorporate hands-on learning while teaching about the earth's layers. The class observes an overhead transparency (linked in Included Materials) as they create their own model Earth using different colors of clay....

A greenhouse provides additional warmth and protection to the plants inside, but what if the greenhouse gets too hot? Pupils discuss and experiment with the difference between natural and anthropogenic greenhouse effect. They measure the...
