It’s summer, which means many of us will be moving into new schools, or cleaning out old ones. It’s not unusual to come across equipment that you have no idea how it is used (even for veteran teachers!). In light of that, we and PTSOS have created a new Twitter hashtag to use our collective wisdom to help identify unknown equipment:
Are you doing something that should be shared with other physics teachers? Will it take more time than the five-minute limit in Share-and-Tell? In that case, please sign up to present either a poster, presentation or workshop. We’ll start the conference with our poster session, and close with contributed talks.

Help the Exploratorium celebrate their 2nd anniversary at Pier 15 on April 17. Share what you love most about our new home for a chance to win a lifetime Dual Explorers membership and a $500 gift card to the Exploratorium Store.
Share your favorite exhibits, views, and memories of Pier 15 for a chance to win a lifetime of exploration, curiosity, and creativity.
The second draft of the Next Generation Science Standards have come and gone (comment period was in January 2013). The January 2013 draft version has been removed from the official website, but you can still find it here.
In their Season Premiere the Mythbusters will take on the infamous projectile problem of a dropped vs shot bullet. While teaching projectiles, many teachers use an example of shooting a bullet horizontally and dropping one next to it at the same time. While students agree that this may hold true for slow projectiles, they often don’t believe that that gravity would act on something moving really fast, like a bullet. On their season premiere tonight, 9pm PST, the Mythbusters will be testing this out in “Knock Your Socks Off.”
WASHINGTON, July 16 /PRNewswire-USNewswire/ — NASA released Thursday newly restored video from the July 20, 1969, live television broadcast of the Apollo 11 moonwalk. The release commemorates the 40th anniversary of the first mission to land astronauts on the moon.
The initial video release, part of a larger Apollo 11 moonwalk restoration project, features 15 key moments from the historic lunar excursion of Neil Armstrong and Buzz Aldrin.
A team of Apollo-era engineers who helped produce the 1969 live broadcast of the moonwalk acquired the best of the broadcast-format video from a variety of sources for the restoration effort. These included a copy of a tape recorded at NASA’s Sydney, Australia, video switching center, where down-linked television from Parkes and Honeysuckle Creek was received for transmission to the U.S.; original broadcast tapes from the CBS News Archive recorded via direct microwave and landline feeds from NASA’s Johnson Space Center in Houston; and kinescopes found in film vaults at Johnson that had not been viewed for 36 years.
NASA Television will provide an HD video feed of the Apollo footage hourly from 12 – 7 p.m. on July 16 and 17. Each feed is one hour. For NASA TV streaming video, downlink and schedule information, visit:
NASA’s Apollo 40th anniversary Web sites provide easy access to various agency resources and multimedia about the program and the history of human spaceflight, including a gallery of Apollo multimedia features. Visit the site at:

WeChooseTheMoon.org “The site will plug you into the current state of the mission and has many tangents to keep you occupied during quiet times (especially the “loss of signal” intervals). Keep the site running in the background while you work away at the tasks of the day.” [Thanks, Dean Baird, for the quote]
Physics educators have used photos of natural and man-made breakwaters to show refraction for probably as long as we’ve had photography. But now online mapping web sites (Google, Yahoo. etc.) allow you to find locations near you to make the images more tangible to your students. Oceans and bays are full of images of refraction, but you may also find diffraction patterns in a large lake.
Below is an example from a breakwater in Berkeley, CA, in the San Francisco Bay

Check water bodies around your institution to find examples you can use with your students. Most mapping sites allow you to save landmarks in a “My maps” section, so once you find a good location, you can save it, then pull it up from a list when you need to show it in class.
One warning: Map sites update their satellite photographs every so often (as the USGS releases newer ones), so check your location before your lecture to make sure your pattern is still there!
