Students perform a simulation of the workings of an electron microscope to discover that the resolution will need to improved to detect objects in the nano-scale. They use wooden dowels as detectors to determine the shape of objects in...

Young scholars identify and interpret the value of the dragonfly as a predator of the mosquito. They create their own folktales using the dragonfly or a creature of their choice to solve the malaria problem or another issue. Students...

In this vectors learning exercise, students draw vectors on three polar graphs and convert the polar components to rectangular components. They then draw the vector on a rectangular graph to complete the learning exercise.

Story elements such as conflict, character analysis, resolution, and moral are discussed and charted as elementary children read folktales involving animals. An element of science is also introduced as learners discover what a keystone...

In this moon crater worksheet, students use images of craters taken from the Lunar Reconnaissance Orbiter to determine the size of the craters. This worksheet has 6 problems to solve.

In this moon craters worksheet, students use a high resolution image of the lunar surface and calculate the image scale in meters per millimeter. They use the image scale to find the largest crater in the image, the smallest crater, the...

In this astronomy optics worksheet, students calculate the angular resolution and maximum resolution for given telescope specifics. This worksheet has 3 problems to solve.

Fourth graders examine written works dealing with environmental issues and resolutions during a 5 week unit. They create posters, poems, and rap songs demonstrating authorship and knowledge of the environment.

Students are able to demonstrate knowledge of natural and artifical satellites. They are able to demonstrate the differeence between "active" and "passive" communciation. Students are able to define radio waves, amplification reflection,...

Twelfth graders explore vector addition and subtraction using an online simulation website. In this physics lesson, 12th graders complete a worksheet package during the simulation. They take a mastery quiz after the lesson.

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...

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...

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...

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...

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.

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.

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.

"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.

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...
