Ptable is an interactive Web 2.0 periodic table. It provides dynamic layouts, property trend visualization, orbitals, thousands of isotopes, and 5 writeup sources. The application uses no Flash or images, giving all the scalability and accessibility of a normal web page (it can be viewed on any kind of computer and device).
The layout, unless differently specified by the user, automatically switch to fit the width of the screen. Using the check boxes at the top of the page allows to dynamically switch between various configurations (simple, with names, with electron configuration, and inline inner transition metals).
In addition to Wikipedia descriptions in all languages, write-ups, photos, videos, and even podcasts are offered in the first tab's dropdown. Write-up windows can even be torn off or docked to the edges to allow simultaneous use of the table while reading.
Data is acquired from primary sources and curated libraries. Layout and presentation were reviewed by the world's foremost periodic table academic, Eric Scerri. Translations and non-English element names, however, should be considered no more reliable than Wikipedia.
Search (into the box at the top right) can be performed by name, symbol, or atomic number. Advanced searches work, for example, on the atomic weight, number of orbitals, etc.
Most browsers, tablets, and phones can store the site and its data for use offline. Firefox prompts you with a notification bar at the top while Chrome and Safari directly save it.

Scratch is a programming language that makes it easy to create animations, interactive stories, animations, games, music, and art. The outcomes can be stored and shared on the web within the Scratch system.
It is not only an ideal tool for the creation of simple and attractive interactive and/or animated learning objects, but it also serves as a learning instrument for young people. By using Scratch learners learn not only to create and share Scratch outcomes but more importantly they learn mathematical, logical and computational ideas, while also learning to think creatively, reason systematically, and work collaboratively.
Scratch is at first sight a bit difficult to learn, but there is a (short and simple) manual that helps everyone getting started within minutes. It is not a full blown animation tool but it is a lot of fun and very rewarding to work with.
Scratch is developed by the Lifelong Kindergarten Group at the MIT Media Lab, with financial support from the National Science Foundation, Microsoft, Intel Foundation, MacArthur Foundation, Google, Iomega and MIT Media Lab research consortia.
amara (powered by Universal Subtitling)
amara (formerly known as Universal Subtitles) is a community platform that allows for easily captionning and translating of the videos one produces, by seeking assistance from the viewers. Subtitling not only increases the geographical appleal of the vides by adding language versions, but also has the additional advantage of making videos accessible for the deaf and hard-of-hearing. The subtitling (translation and subtitle text addition) is done by volunteering viewers, like a wiki: easy, free and fast with no software to install. As of today August 15 2011) over 117000 videos have already been subtitled with Universal Subtitles.
Amara gives individuals, communities, and larger organizations the power to overcome accessibility and language barriers for online video. The tools are free and open source and make the work of subtitling and translating video simpler, more appealing, and, most of all, more collaborative.
The benefits of captioning and subtitling are immense:
- Captions make videos accessible for viewers who are deaf or hard of hearing
- Translations make it possible for all of us to watch video in languages that we don't speak
- Video creators get: better SEO, more views, access to a far bigger (potentially multilingual and global) audience, accessibility for deaf and hard of hearing viewers, and more
Amara is composed of three main parts:
- A subtitle creation and viewing tool (aka the widget)
- A collaborative subtitling website
- An open protocol for subtitle search/delivery

The Divis project (Digital video streaming and multilingualism) is a European funded Project that run from October 2008 to September 2010. It aims to encourage, motivate and equip both teacher trainers and practising language teachers to include video production in their teaching.
The official report of the project is available here:
Initial research was undertaken to establish how teachers feel about the use of video production and what skills and experience they had in this area. From the results of the research, the project team developed a online guide to address the teachers' needs, introducing creative and non-conventional teaching methods and samples to support implementation of video work in the classroom as well as providing technical support. The manual is available in many languages on the following webpage:
On the Divis project website, you can also find very good examples of usage of videos, photo stories, dramas, and television news in education. There is also a useful technical support section:
Photo story, Video words, school presentations, drama, television news, technical support, Video gallery, download guide
DNA from the beginning
DNA From the Beginning is organized around key concepts of classical genetics, molecules of genetics, and genetics organization and control. The science behind each concept is explained by animation, image gallery, video interviews, problem, biographies, and links.
This site and its sections or chapters include references, images and a bit of information on several key figures in these areas such as Mendel, Miescher, Levene ...
The feature "option" is a basic game / quiz in which your knowledge is tested.
3 Main sections:
- Classical Genetics
- Molecules of Genetics
- Genetic Organization and Control
Each topic has subsections:
- image gallery
- video interviews

The Europeana online portal was launched by the President of the European Commission in November 2008 and currently provides access to over 19 million objects from European libraries, museums, archives, galleries, and audiovisual collections.
These objects include:
- Images - paintings, drawings, maps, photos and pictures of museum objects
- Texts - books, newspapers, letters, diaries and archival papers
- Sounds - music and spoken word from cylinders, tapes, discs and radio broadcasts
- Videos - films, newsreels and TV broadcasts
More than 1,500 heritage institutions contribute cultural content in Europeana. Their number and geographic coverage are steadily growing.
The objects relate to science, media and art. They are available in different formats (text, images, audio/video, etc.) and in every European language.
