On Tuesday, we received the visit of 3 sciences from the University of Navarra. They conducted several experiments related to different branches of science:

Physics:

-Magnets: how they repel and attract and even float!

-Light: using a laser we tested how it travels, where it reflects, and how we can create 3D effects using concave mirrors and a small plastic frog.

Chemistry:

-Changes of state and exothermic reactions can be useful to keep your hands warm in cold weather.

-Combustion of chemical elements and the different colours they produce.

-Chemical reaction when we mix hot oil and water.

-Exothermic reaction when there are mixed soap, acetate and hydrogen peroxide.
