When the moon passes through the Earth's shadow, it causes the moon to look very unusual for a short period of time. This event is called a lunar eclipse, and it occurs roughly twice a year. There's one viewable to folks outside of North America on June 15, so sit back and learn more about how lunar eclipses work in this video!
A really interesting video that can be used to teach natural selection. Discusses many of the behaviors of plants that help them to survive, thrive and reproduce.
On this page you will find the essential standards organized by quarters. Each quater has a variety of pdf files and online quizzes. Students that utilize these resources will be well prepared for the quarterly benchmarks and the end of year MSL exam. (Some pdf files are larger than others and may take a while to download. You can save the pdf files to your computer for faster access in the future.)
"In science fact, though, there's greater concern that Earth-dwellers-specifically bacteria and microorganisms-could arrive at extraterrestrial destinations.
As NASA sends rovers to Mars, plans a trip to Jupiter's icy moon Europa, and looks for an ocean on Saturn's moon Enceladus, the hope is to find life-forms on those interstellar bodies. To ensure that doesn't include forms that originated on Earth-and that the new environment isn't compromised the way Earth ecosystems can be by invasive species or infectious diseases-NASA is now thoroughly cleaning its space-bound vessels."
SciShow describes the fascinating science of Darwin's little darlings: meat-eating plants. Learn about their many different types, how they catch and eat their prey, and how scientists think they evolved.

Photosynthesis was written and created to help students learn and remember the process we all love and call, "Photosynthesis!". Visit www.learningscienceisfun.com for more videos, curriculum and fun science stuff.
Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we're pretty fond of as well.
SciShow takes you down the deepest hole in the world -- Russia's Kola Superdeep Borehole -- explaining who dug it and why, and what we learned about Earth in the process. Don't fall!
However, a little known fact about this flight is what took place before it. Shepard sat in the rocket for five hours because of delays, and the astronaut really had to use the restroom.
The video introduces mineral properties using common fruit and vegetables as analogies for these five descriptive criteria. The video also demonstrates the orderly crystalline structure of halite (NaCl) using a model made of food (marshmallows and grapes). Comparisons between common substances such as ice and glass versus the mineral definition are made to illustrate the specific nature of the mineral definition.
We bet you thought that rocks are just rocks, but the truth is there are three different kinds of rocks. Learn the differences between sedimentary, metamorphic and igneous rocks.
According to the study: "For five metals (arsenic, cadmium, lead, manganese and zinc), strong correlations of concentrations in uncultivated soils indicate a common source, suggesting that emissions from the complex may be a major contributor to elevated concentrations of these five metals in uncultivated soils in this area.
