Wow Lab programs address a real challenge existing in the current formal education: the insufficient occasions and time to approach the practical side of science. Our mission is to capitalise on experimentation, observation and critical thinking in the learning process, complementary to the theoretical information obtained in school. Thus, children understand more easily the natural phenomena around, the connection between them and the scientific notions that they refer to. With us, learning is not based on memorising information, but on the direct interaction with the experiments the kids run for their own and on the quality of information.
