Learning by Seeing: Fun Visualization Tools That Educate

Jim Moulton

Technology Integration and Project-Based Learning Consultant

One recent morning, I sat in the window seat on a flight home from foggy Atlanta, Georgia, to Maine. As we gained speed heading down the runway, I watched the wing and noted the fully extended flaps. As soon as we lifted off and entered the fog layer some 20 feet up, an intense cloud rolled off the upper surface of the wing. When I saw this phenomenon in action, I immediately thought, "A-ha! Bernoulli's principle!"

The shape of an airfoil (especially when the flaps are extended to exaggerate the airfoil) is such that the air moving across its upper surface has to go a greater distance, and, therefore, faster. This creates a reduction in the air pressure on the upper surface, and allows the relatively greater pressure below the wing to lift the plane into the air.

The roiling cloud I witnessed was the moisture being squeezed out of the damp, foggy air moving across the top of the airfoil and becoming compressed like a sponge, thus leaving less room for water molecules. It was fascinating to see it happen, and even better that I could recall my understanding of Bernoulli's principle -- something I had not thought about in years.

Like the real-world example above, following are a few of my favorite Web-based resources to help teachers explain -- and get their students to understand -- complex topics in new ways:

  • Learningscience.org provides a comprehensive collection of tools for teaching science. The site offers several areas to visit, and specific tools for each are organized by grade level. Learningscience.org is a collaborative project of the Central Bucks School District, in Doylestown, Pennsylvania, including curriculum coordinator George Mehler and district teachers, and the College of Education at Philadelphia's Temple University. Don't miss the Tools of Science section!
  • From the Maine Mathematics and Science Alliance, PRISMS (Phenomena and Representations for the Instruction of Science in Middle Schools) is a resource, as the site states, of "reviewed phenomena and representations" for middle school teachers and students. Another great collection of science visualizations!
  • Utah State University's National Library of Virtual Manipulatives offers classic classroom materials such as tangrams, geoboards, and more. Check out the Algebra Balance Scales, for grades 6-8 and 9-12. I've had so many teachers tell me, "If only I had had this resource when I was in school!"
  • CSERD (Computational Science Education Reference Desk), a Pathways project of the National Science Digital Library, brings us Project Interactivate and its collection of middle school-based mathematics tools. Be sure to check out the Discussions -- they're like a reader's theater for math!
  • The Visuwords online graphical dictionary uses Princeton University's WordNet, an open source database created by university students and language researchers. You have to play around on this site to learn how to maximize what it offers. It is color coded; floating your cursor over any word delivers a definition. How about asking students to put their vocabulary words in and see what comes up?
  • Ricci Adams's Musictheory.net gets you started with a choice of Lessons, Trainers, or Utilities. I'm not a musician (just ask my family), but I like the way this site helps me better understand the language of music. Check out the pop-up piano!
  • Playing with Time takes a look at how the world changes over a given period. This collaboration between Red Hill Studios and the Science Museum of Minnesota allows you to view time sped up and slowed down, and offers activities and collaborative projects that illustrate just how complex time really is.
  • Powers of Ten, from the Eames Office (a gallery and store devoted to the works of designers Charles and Ray Eames), is where you'll find the classic Powers of 10 film and so much more to help teachers and students alike better understand scientific notation. (That whole exponential-growth thing can be a real head-shaker!)
  • NetLogo, developed by Northwestern University computer scientist Uri Wilensky, is a great free, downloadable tool for visualizing complexities -- everything from forest fires and predator-prey relationships to HIV.

I'd be interested to know what you think of these sites, and if you know of others, please share!

I thought you would like this visual organizer that shares another type of visualization. That is with a search engine.

Thanks for the links. These are terrific examples of the ways in which online visualization can be applied. I am still looking for online or freeware tools that will allow teachers and students without advanced programming knowledge to create customized visualizations. I teach elementary and middle school and would like to use and help students create their own simple animations and "clickable" interactive images to illustrate concepts they are learning.
I have looked at NetLogo and some of my students have been working with Alice (from Carnegie Melon). We have also used action buttons in PowerPoint and I plan to use Google Maps with them to create a clickable map. Are you aware of any other resources for tools like this?

Real life, visual learning is truly one of the best ways to teach...good job on this lesson.

The NLVM site also works great for teaching arts concepts to kids K-12 (I'm one of 3 resident visual and performing arts teachers).
We're working to give teachers methods for using the arts to teach other subjects.
Thanks for the excellent links.

I just browsed through learningscience.org. It looks like a great resource. My school has a laptop cart which will be in my classroom next week. I may try some of the activities with my students. I will also add the link to my website for students to supplement class work at home. Thanks for the link - I am always looking for good resources for my seventh and eighth grade science students.

Thank you for your insight on the lesson, it seems to be a great life learning experience. Learning visually is something most student do to fully understand a concept. Also I loved the links, they provided much used information. Good job!

Thank you for the wonderful resource ideas. I teach 8th grade math and am always trying to find new ways to capture my students. The BIG problem I have is finding the time to locate and fine tune the resources to make them fit the lesson. Any suggestions on how to find extra time??

Thanks for all the links! I find visualization to be such a vital thing across the curriculum. My school is really pushing visualization throughout Language Arts. I am also constantly working to incorporate real-life examples into my student's learning. Thanks again!

What great links! Although most do not apply to the courses I teach, I have already passed them on to the Health, Math, and Science departments.I had great fun going to many of the sites. This my first involvement with blogging and now I am inspired to hunt for bloggs related to Family and Consumer Sciences. Thanks!

Jim: These are really great websites! I am an Earth science teacher in metro-Atlanta who is always looking for new ways to incorporate technology into the classroom. I find that students become more intrigued with the content when it is presented in a visually appealing manner. I typically introduce my lessons with PowerPoints with flash videos embedded in them. These websites are ideal for what I do...thanks!
