The Framework for Remote Experiments in Education (FREE) is the new platform elected and developed to support our Laboratories. We are moving all experiments to this new website, with mobile support, and soon most of elab experiments will have a new shape.

We apologize for any inconvenient if your favorite experiment is unavailable in elab, soon you will find it at free.elab.tecnico.ulisboa.pt. For the time being we are publishing direct links for each control room in our wiki in the “Links” collapsible section of each experiment description.

Some browsers, due to their configuration, will refuse to launche e-lab unless you update for the last JAVA version, which will NOT run e-lab and many other free software. PLEASE KEEP your JAVA 6 version in your computer and turn around following the sequence:

1) Download directly the program file (.jnlp) from here; From the download tab check were it was stored in your computer (by clicking with the right mouse button and selecting “Open destination folder”)

2) Access the command prompt or console (ex: running CMD);

3) Change to the directory you have download the .jnlp file (eg: cd .\AppData\Local|Temp);

4) Execute the JAVA Web Start by issuing the command
>javaws elab-client.jnlp
or
>javaws elab-client-XX.jnlp , where XX is the last version downloaded (check by doing a >dir)

Please accept all the risks for being educated.

It was deployed a new e-lab experiment to measure the linear momentum conservation where the collision can be viewed in various inertial frames including the centre of mass (colisione). This last experiment was supported by the “Escolher Ciência” program and is host at  Externato Cooperativo da Benedita.
In parallel with the Boyle-Mariotte experriment at ESPAV, this experiments are the demonstration of e-lab distributed versatility. See the movie at Colisione HD Movie.

At Externato Cooperativo da Benedita, Portugal, was released a “Flintstones” pendulum following some work around the World Pendulum.
This pendulum was created with recycled and raw materials and is a very good example from students’ creativity .
