• Students questions seem to disappear along withtime.
• Students show lack of motivation when learningScience.
• The above situation is dependent of:
- Classic teaching approach;
- Missing contextualization of scientific concepts.

A study performed in 2006 [1] suggests thatexperimental work and new technologies arevaluable resources to increase motivation ofstudents in science learning.
• The e-lab platform has the above valences.

Allow teachers' and students' access to a laboratorywhere is possible to collect data in real time.
• Perform experiments that need expensive materialand without concerns with safety precautions.

• Physics and Chemistry in Portugal are frequentlyrejected by students because of the referreddifficulty of their curricula [2], however, areimportant subjects to the construction of students´scientific literacy knowledge and to their academicpath in our technological society.
The essential objective of this study is to proposeways to invert the earlier aspects using technologiesand experimental work.

Actual studies confirm the importance of newtechnologies and experimental work in scientificsubjects using the STS metodology (like e-lab).
Problem-based learning with experimental work andtechnologies places students in contextual learningsituations, creating an education of meaning ratherthan an education of fact collecting.

Teachers continuous training is always importantand necessary, but in e-lab platform case aims to:
- help teachers with e-lab interface;
- help teachers on planning and preparingexperimental work;
- motivate teachers and students.

Experiments explored by teachers:
- determination of gravity value (on Earth);
- pressure change with volume (Boyle-Mariotte law);
- pressure change with depth (hidrostatic law);
- launching data (statistics).

At the end teachers are expected to:
(i) know how to use the e-lab interface;
(ii) know the experiments that already exist;
(iii) have a global vision on the e-lab internalstructure and functioning;
(iv) be able to contribute to the improvement of e--lab interface;
(v) be able to propose others experiments andresources;
(vi) propose and know more scientific resources.

Enthusiastic inquiry results
The use of experimental work and/or technologies inclassroom seems essential to motivate students toscientific areas [1, 3, 4, 5]
• We believe that e-lab is a proper tool forexperiments data collection using a simple,functional, user-friendly platform with all thenecessary resources for students and teachers
