Deep Below Antarctic Ice, Lake May Soon See Light
hide captionWhile a team of Russian scientists were drilling ice core samples from their Vostok base in Antarctica, new satellite imagery revealed the outline of a lake the size of New Jersey buried two miles underneath the ice. Scientists have been drilling through the ice and are now just 100 feet away from breaking into the third largest lake on the planet. Earth Observatory/NASA Russian scientists are on the verge of punching a hole into a vast Antarctic lake that's buried under more than two miles of ice. If the Russians break through, they may tap into and disturb a primitive and pristine ecosystem that has been untouched for millions of years. Lake Vostok is actually the third largest lake in the world, measured by the amount of water it holds. In fact, they had no idea there was a lake there when they built their Vostok camp more than 50 years ago. "The Russians went to the magnetic South Pole in 1958 because they missed the race to the rotational South Pole," Bell says.
Common Core Science Informational Text Task Cards
These task cards can be used with ANY science reading passage. In my school, every teacher is required to teach subject area lessons that emphasize or reinforce Common Core standards. One day each week, we run a special schedule in order to accomplish this. During this time, I meet with a small group of my students to apply the Common Core standards to a science-related lesson. Students read a passage from the textbook on a topic we are currently studying. As a result, I developed a set of “Common Core Science Task Cards” to use with my students each week. This has very much simplified my weekly lesson planning. These common core science task cards are incredibly easy to use! I like to punch a hole in the corner and place all of the cards on a ring. I have correlated each task card with the appropriate CCSS standards from: 1. 2. Now that I have the set fully developed, I am looking forward to school starting back. Have fun teaching!
Cultiver son jardin… au naturel
Dans le verger de l’Université d’Orsay, Daniel Chollet propose aux jardiniers des techniques naturelles pour faire prospérer leurs cultures. Ce souci d’agir en symbiose avec l’écosystème est partagé par l’entomologiste Vincent Albouy. Efficaces, ces méthodes pourraient semer des idées chez les agriculteurs qui veulent abandonner l’usage d’intrants chimiques ou le labour classique. Les bandes florales du verger d’Orsay sont riches en nectar et pollen qui nourrissent les insectes auxiliaires entomophages (insectes qui mangent d’autres insectes) et parasitoïdes (insectes qui pondent leurs œufs dans le corps d’autres espèces) ; à certaines périodes de leur cycle biologique, cette nourriture leur est indispensable. Dans un jardin naturel, considéré comme un "jardin du fainéant" par l’entomologiste Vincent Albouy, point de labour, point d’irrigation et sus aux traitements. C’est une façon idéale d’entretenir un verger conservatoire comme celui de la faculté d’Orsay.

How to Make a Hovercraft
If you're on Pinterest, chances are good you've seen this activity. But for the few who haven't, get ready for some seriously cheap science fun. We made a hovercraft! Supplies An old CD that you no longer need Glue gun and glue sticks thumbtack soda bottle screw top (you want one that's fairly deep) latex party balloon Assembly Poke several holes in the plastic bottle top with the thumbtack. Use a hot glue gun (Adults, please. You're almost done. Now blow up the balloon. Ask your child to make predictions. Let it Go Set on a flat surface like a countertop or wood floor. Invite the child to form a hypothesis about why and how this works. How it WorksThe force of the air that exits the balloon as it deflates goes through the holes in the bottle cap, pushes against the surface (floor or counter), and creates a cushion of air over which the CD glides freely.

Explore the Sky . Your Sky Tonight
Our star chart is designed to get you out learning the night sky within a matter of moments. Just set it for your time and location, make a few tweaks if you like for personal taste, and print it out. For stargazing, pick a location that's as free as possible from bright local lights, and give yourself at least half an hour outdoors so that your vision becomes fully dark-adapted. It's also easy to customize the star chart for use with binoculars or a small telescope. First, check your location. Then pick a direction. Field of view: Our chart defaults to a naked-eye field, so if you're learning constellations or spotting planets, leave the chart on that setting. Display options: For most purposes starting out, you may wish to leave these as they are. Equatorial Grid shows lines or right ascension and declination—the longitudes and latitudes of the sky. When you've got the chart you want, just click for a print version, print it out, and head outside to see nature on its largest scale!
