See How Bolts Are Made!

May 3rd, 2013

Hi!  It’s Friday, May 3, 2013 and time for a Virtual Field Trip at ClickSchooling!

Recommended Website:

Portland Bolt & Manufacturing Company

Age Range: 9 and up (approximately, with parental supervision)

At this website you can watch a five-minute video on how bolts are manufactured.

You may know that the building of a new San Francisco Bay Bridge, the world’s largest single-tower, self-anchored suspension span, is underway. You may have also heard that one third of the 96 bolts (threaded steel rods that are 3 inches in diameter and 17-24 feet long) broke after workers placed them in March 2012. The bolts were used to connect the bridge at the pier to help control swaying and seismic uplift during an earthquake.

Metallurgy experts suspect that galvanizing the steel bolts trapped hydrogen atoms beneath the zinc coating causing the bolts to become brittle. 

Interestingly, the company featured on today’s website, declined to submit a bid on manufacturing the Bay Bridge bolts because of the riskiness of the galvanizing requirement. (Galvanizing this kind of bolt is prohibited in the Caltrans bridge design manual – but engineers opted to do it anyway! They haven’t explained why.)

When you get to the website, you can read about the history of the Portland Bolt & Manufacturing Company. Scroll down to the end of the page to find the video, “How It’s Made: Portland Bolt.” Then click on the arrow to watch the video that includes:

Rock-It Science Videos

Age Range: 7-14 (with wiggle room, and fun for all ages)

First, I’d like to preface this review by saying I know the Founder of Rock-It Science. His name is John McChesney, and the kids fondly refer to him as “Mr. Mac.”  My sons took homeschool science classes from him for about 6 years. That’s how much his brand of science education appealed to them – they couldn’t get enough! 

So, I’m excited to tell you that you and your kids can watch some Rock-It Science Videos of classes and fun experiments for free!

When you get to the site you’ll see a menu of videos that include:

*Meet “Mr. Mac” – Find out who the quirky genius is behind these innovative science lessons.

*Dry Ice – Watch a series of experiments showing the amazing properties of Dry Ice.

*Air Pressure – Watch the video and then try some experiments in your own kitchen!

*What Happened to Japan’s Nuclear Reactors? – Get a kid-friendly explanation of what happened to Japan’s nuclear reactors after the earthquake and tsunami.

*How to Light a Match – Find out the safe way to handle matches, and use flames in science experiments.

*Crash Test Dummies – See how students (ages 11-16) build a device that will protect an egg during a crash.

*Global Warming – Hear and see Mr. Mac’s explanation of the “Greenhouse Effect.”

When you’re through watching the videos poke around the site to learn about the history of Rock-It Science, their mission, and read Mr. Mac’s blog.

 

Tsunamis & Earthquakes (Special Edition)

March 11th, 2011

Hi!  It’s Friday, March 11, 2011 and time for a Virtual Field Trip at ClickSchooling!

SPECIAL EDITION:  Because of the devastating earthquake and tsunami in Japan, instead of a Virtual Field Trip, this issue of ClickSchooling offers information about natural disasters including what causes them and emergency preparedness. My heart goes out to everyone affected by this disaster.

Age Range: 5-18 (varies; with parental guidance)

Recommended Websites:

PBS: Savage Seas – This site offers a tsunami simulator that allows you to create a virtual ocean wave. You’ll also find facts and information on tsunamis, freak waves, trade winds, and more.

FEMA (Federal Emergency Management Agency) – Offers information on disasters and disaster preparedness for children (about ages 6-12) including:

Earthquakes for Kids – Learn the science of earthquakes, the history of earthquakes, get the latest earthquake information worldwide, see animations, and learn how to become a geologist and/or an earthquake scientist.


International Tsunami Information Centre – Offers several educational resources including:

*The Great Waves – A  free, downloadable, 12-page booklet that explains what a tsunami is, how fast and how big they can be, what causes them, and describes programs undertaken to mitigate this hazard, including the development of tsunami warning centers, and safety rules describing what to do when a tsunami strikes your coastline. Available in English, Spanish, French, and Chinese.

*K-12 Tsunami Curriculum – These downloadable publications are divided into two grade ranges (Kindergarten-to-Grade Six, and Grades 7-12). Each topic includes information, activities with exercise sheets, and a teacher’s guide.

The National Oceanic and Atmospheric Administration offers the following information: *Tsunami Warning Brochure for Kids

I hope this information brings great understanding about these natural disasters.

Earthquake Science

USGS: Earthquakes for Kids

Age Range: 8 and up (approximately – there are aspects that will appeal to people of all ages)

Due to the massive earthquake in Chile on February 27th (magnitude 8.8 on the Richter Scale), I thought your children may have questions about earthquakes. At this USGS website (designed for kids) you can learn all about the science behind earthquakes and much more.

When you get to the site you’ll see a menu of items that include:

*The Science of Earthquakes – Discover what happens when two blocks of the earth suddenly slip past one another and better understand terminology like fault, fault zone, magnitude, Richter Scale, hypocenter, and epicenter.

*Latest Quakes – View an interactive map of the world indicating where and when earthquakes have happened.

*Become an Earthquake Scientist – Learn how a geophysicist studies the Earth using gravity, magnetic, electrical, and seismic methods.

*Animations – Watch incredible animations of liquefaction, strike-slip fault, thrust fault, wavefronts, foreshocks and more.

*Puzzles and Games – Get coloring pages to print, take an earthquake quiz, enjoy an interactive word search puzzle, use a calculator to see how much bigger a magnitude 8.7 earthquake is than a 5.8.

You’ll also find terrific links to further resources, science projects, and “Earthquake ABC’s.”

Then, learn what to do to stay safe in an earthquake at FEMA’s website.

FREE Unit Study: How the Earth Works!

April 12th, 2005

Recommended Website:
How Does the Earth Work?

List member, Tammy Watson, recommended today’s website for budding geologists and as a great supplement to any celebration of Earth Day (the 38th anniversary celebration is on Friday, April 22nd, 20011).

When you get to the site you will see an introduction that outlines the four lessons designed for elementary students. This is similar to a webquest, in that students go to various recommended educational websites to find data to complete their assignments. The lessons include:

  1. The Layers of the Earth — Accept an assignment to investigate what the Earth is made of and how it works — including convection currents!
  2. Plate Tectonics — Become a News Reporter to inform your readers about the Super Continent of Pangaea and Plate Tectonics.
  3. Volcanoes and Earthquakes — Become a Volcanologist and learn to collect data and graph volcanic eruptions.
  4. The Difference between Climate and Weather — Discover what meteorologists do — analyze climate data!

You can follow the lessons in the order prescribed or use each lesson independent from the others to explore an area of interest to your particular student. This is a great use of web technology to further education.
