This week I was updating the links in several of my books, and I had an epiphany. Wouldn’t it be great if the links were evergreen and NEVER became outdated? If you write or publish in any media, take a look at my article: “Prevent Link Rot in your Published Work”
=============> Surfnetkids Resource of the Week: Postcards =============> I’m introducing a new section, where each week I’ll highlight a different part of the Surfnetkids site. This week we added two new postcards (Santa Claus and Hannukkah) to the Surfnetkids Postcard collection.
Today’s newsletter is brought to you by the following sponsor. Please take a look at their offer; without their support, this newsletter wouldn’t be possible.
Just for DVD Owners Rent DVD movies online and have them mailed to your home with Netflix.com. I love renting DVDs from Netflix.com because I can rent as many DVDs as I want each and every month for one low monthly fee. Here’s what we watched this month: * A Beautiful Mind (PG-13) brought tears to my eyes * Mrs. Doubtfire (PG-13) kids had never seen it; I never tire of Robin Williams * Nine Queens (R) an intricate Argentinian con-artist plot with an unexpected ending
Coming up we’ve got: * Parent Trap (PG) the 1998 Disney remake is one of my daughter’s favorite see-it-again movies * Pillow Talk (unrated) for a dose of Doris Day and Cary Grant Try it yourself and see!
See ya on the Net, Barbara J. Feldman “Surfing the Net with Kids”
P.S. This week Printables Club Members also: 1) learn where to find online museums 2) learn about online paint-by-numbers 3) learn where to find snail mail and email addresses for the White House 4) get a two-page Internet enrichment printable of today’s topic 5) get access to an archive of +100 Surfnetkids Internet enrichment printables and word searches
The science of sound can be explored at many different levels, from grade school to college physics. Whether your interest is in making drums with first graders, or doing research for a physics project, this week’s site selections will deliver with animations, tutorials, activities and experiments that uncover the many facets of sound.
These eight interactive wave motion demonstrations for middle-school and high-school students are awesome. The first activity, Sound Beats, allows you to experiment with sounds that are very similar in frequency. Based on what you learn, can you determine the frequency of the mystery sounds? In Doppler Effect 1, you can watch sound waves originating from a moving source. You’ll learn why a train whistle changes in pitch as it passes you and how sonic booms are created.
This collection of animations will help first-year physics students visualize and better understand the science of sound and light waves. You can step through the animations, following the menu on the left, or you can jump to the Physics Tutorials on “Waves” or “Sound Waves and Color.” The tutorials are divided into lessons that include self-scoring quizzes. Can’t find the answer to your homework problem? Questions can be posted in the homework help forum; look for the link on the About page.
“Sound is a compression waveform that moves through air or other materials. Sound waves are created by the vibration of some object and are detected by causing a sensor to vibrate. Sound has the standard characteristics of any waveform.” This one-page middle-school lesson introduces the concepts and vocabulary of sound (such as amplitude and wavelength) and concludes with a three-question quiz.
Click on the bouncing ball (you’ll hear it boing, boing, boing if you have QuickTime installed) to enter my pick-of-the-day site for elementary students. Created by the Science Museum of Minnesota, Sound Site is divided into four sections. Visit Activities for ten offline experiments, such as Making a Model Eardrum or Designing a Reed Instrument. Discussions is a collection of audio interviews about the art of composing music. Performance takes you behind the scenes of a Minnesota Orchestra premier. Soundcards are noise snippets you can share with friends via e-postcards.
The Soundry is an award-winning ThinkQuest Internet Challenge entry from 1998, created by three high-school students. To get the most from The Soundry, you’ll need to familiarize yourself with their menu abbreviations used at the bottom of each page. Clicking on A will take you to page discussing Applications of the topic. P is for the Physics behind the topic. My favorite Soundry clicks are the Interactive explorations found at I.
