Are New Orleans’ post-Katrina flood defenses strong enough?

This 8.5 minute video from PBS Newshour explains the current situation in New Orleans. Experts examine the new man-made defenses, and look at the causes and impacts of delta erosion as well. - Lots of interesting Earth Science here.

Astronomy Interactives/Animations from U. of Nebraska

Here is an incredible collection of astronomy resources for you to examine (play with) in your spare time this summer. This motherlode of animations and interactives is provided by the University of Nebraska - Lincoln. One of my favorites is their Planetary Orbit Simulator, which demonstrates Keppler's first and second laws of planetary motion. Be sure to play with the settings!

Also, here's another fun site that shows the current location of the planets. CLICK HERE to take a look. You can change the settings in the windows beneath the image. The site is developed and maintained by Chris Peat of Heavens-Above.

NOTE: This will be the last post for awhile. School is winding down and my days will soon be spent hiking, kayaking, etc. Have a great summer!

To view a convenient list of all the resources that have been posted on this "Earth Science Guy" blog site, CLICK HERE.

Watch the New Meteor Shower Friday Night (May 23)

This might be worth staying up for. This NASA ScienceCast video provides all the details. Hopefully the skies will be clear where you are. The shower will happen as Earth passes through debris from Comet 209P/LINEAR. Experts aren't sure whether it will be a dud or a magnificent event.

Go "Retro" - Retrograde Animation

Retrograde motion is a tough one to explain to students without some sort of visual aid. This animation by the University of Nebraska is a very helpful tool. CLICK HERE to watch it.
