Free, Amazing Math Movie with Lessons in Geometry & Dimensions

Dimensions

(www.dimensions-math.org/Dim_E.htm)

Age Range: 12-18 (Grades 7-12, with parental supervision)

 

Created by three math enthusiasts (with terrific credentials) this site offers a free film on mathematics that references the work of renown mathematicians, scientists, artists, and others in a multi-media presentation that is sure to amaze and (hopefully) make the subject matter understandable.

When you get to the site, click on “Tour/Guide” to get an overview of the course. Then click on “Watch Online” and choose “American English” to start the video in English. Of course, if you prefer, you can watch it in German, French, Spanish, Italian, Japanese, Russian and Arabic.  

Back on the main page, click on “Details” so you can follow along by chapter: 

  • Chapter 1, Dimension Two – Learn or review what meridians and parallels are.
  • Chapter 2, Dimension Three – Mixes “elementary” math with imagination and philosophical elements.
  • Chapters 3 and 4, Fourth Dimension – Contains more difficult mathematical concepts. However, the viewer is encouraged to pause the film and consult a reference page for additional information. As the creators explain, “you can always sit back and enjoy the pictures!”
  • Chapters 5 and 6 – Contains an introduction to complex numbers that could also be used as a refresher course. As the designers explain, “If you know nothing about complex numbers, you should push the pause button as often as you like, and try to understand using the references that we propose. These chapters are the most ‘school-like’ of the film. To thank you for your efforts, chapter 6 ends with an amazing deep zoom scene.”
  • Chapters 7 and 8 – Get an introduction to the Hopf fibration. Again the film creators explain that even though it’s not beginner’s stuff, “it is quite pretty and deserves to be understood.”
  • Chapter 9 – Shows the proof of a theorem of geometry that is relatively “elementary.” As the designers explain, “Without proofs for theorems mathematics would not exist, and we wanted to make this very clear at the end of a film that is essentially about mathematical objects.”

Each lesson or “chapter” of the film is almost 14 minutes long. Watch it in segments or sit down and watch the whole thing in one sitting. You are encouraged to use it in a way that works for you “based on your interest, your prior knowledge on the subject, or simply on your mood of the moment!”

Happy Earth Day tomorrow! This website offers FREE science education journals: “The Natural Inquirer,” for middle and high school, “Investi-gator” for upper elementary, and readers for PreK-2. Scientists with the USDA Forest Service share their research in a fun and engaging way.

Each issue of “The Natural Inquirer” introduces students to the scientists who conduct the environmental research and includes an article or more on a specific research project. Some of the issues are entitled: 

  • World’s Forests
  • A Burning Question
  • Chew on This!
  • Full Throttle Model
  • Fresh Water
  • Wilderness
  • Flower Power
  • And more!

Each issue also contains a “Discovery FACTivity” designed to help students learn scientific vocabulary words included in the articles. There are also discussion questions designed to help students think more about research. You can download the issue(s) you are interested in or order hard copies (only 5 issues at a time).

Be sure to check out the left side bar under “For Educators” for links to lesson plans, science cards and posters, and more.

This is a treasure trove of environmental learning resources! Bookmark this one, as you’ll need to visit many times to explore the vast content!

The Great Backyard Bird Count

The Great Backyard Bird Count

Age Range: All (All grades, children with parental supervision)

 

Mark your calendars and get ready to participate in “The Great Backyard Bird Count” scheduled for February 14-17, 2020.

This annual event, sponsored by the Cornell University Lab of Ornithology and the Audubon Society, is your opportunity to join a citizen-science project (for kids, teens, and adults) that helps scientists collect data and investigate far-reaching questions about bird populations.

It only takes as little as 15 minutes on one day. You simply count the birds you see in your backyard and turn in the results. It’s free, fun, and easy – and it helps the scientists to help the birds.

To learn how to participate go to The Great Backyard Birdcount website. Use the menu to register, learn about birds, and view the bird photo gallery.

Now, if this sparks your family’s interest in birds, you are sure to enjoy this website: WhatBird.com. Use a tool that helps you to identify a bird by what it looks like. You simply enter its attributes such as habitat, size, color, body shape, bill shape, etc., to drill down results, choosing as many options as you can along the way.

The 60+ Symbols of Astronomy & Physics

Sixty Symbols

Age Range: 6-18 (Grades 1-12, with parental supervision)

 

This fantastic website offers FREE videos about physics and astronomy featuring experts from The University of Nottingham, who explain the strange letters and squiggles (many more than 60 of them) used by scientists.

As explained at the website, “Sixty Symbols is a collection of videos by experts from The University of Nottingham. It’s worth noting many symbols have multiple uses across scientific disciplines and we sometimes tackle them from an unexpected viewpoint.” Here’s some of what you’ll see: 

  • Click on “E” for energy and see an Einstein doll on a swing as a demonstration of potential and kinetic energy.
  • Click on the symbol for the planet Venus (looks like a hand mirror) and learn all about it. You’ll also learn the history of the symbol and its use as the universal symbol for women.
  • What has a symbol of a cat got to do with physics? Visit the site, click on the cat and find out!

When you get to the site you’ll see the table of Sixty Symbols (and then some). Click on any one and a new page opens where a video launches that explains it. They are wonderfully engaging and educating.

Fun Periodic Table of Videos

Periodic Videos

(www.periodicvideos.com/)

Age Range: 8-18 (Grades 3-12, with parental supervision)

 

What a find! This website teaches the periodic table with videos!

When you click on an element on the periodic table, it plays a video showing educational experiments and explanations about that element. (Okay, while this site is probably designed for middle school, high school, and beyond, younger children will enjoy seeing some of the experiments. Plus, we’ve found that little kids lap up information about the Periodic Table, so don’t be shy about introducing them to it.)

This is so much fun! Each video is short (up to about 10 minutes) and provides basic information about the featured element, it’s history, and how it is used. You can tell the chemists, who narrate while demonstrating experiments with the various elements, love what they do!

Consider starting with Lithium (Li). It’s very reactive in water and the clip is fun to watch. Then try Hydrogen (H) or Helium (He) to see a big bang! (Careful – kids may be tempted to try this at home, so parental guidance and safety discussions are required.) The Phosphorus (P) video will really amaze your kids when they learn there’s about a pound of this reactive element in their bodies!

The scientists in the lab have a lot fun demonstrating the properties of the elements – and their antics with beakers, Bunsen burners, and bloopers are narrated by mild-mannered professor Martyn Poliakoff who has wonderful, wild, Einstein-ish hair! Some of his descriptions are hilarious – such as when he describes what can be done with Nitrogen (N). (Preview it, as it might alarm younger children.)

Note: We didn’t watch all of the videos. Therefore, parents AS ALWAYS should preview the videos BEFORE showing them to children to determine suitability of content.

The Periodic Table of Videos is educational, fun, and not to be missed!
