“Visit to the museum of science and technique”

Last week we went on a trip to Terrassa to visit a science museum, “Museu de la Ciència i de la Tècnica de Catalunya”. We met at 10:45 in Plaça Catalunya to take the Catalan railways, Jordi and Júlia didn’t meet us there since they were going directly. Once there, the first thing we did was to have our breakfast. We had to wait for Jordi, because he took the wrong train. Once he arrived, we entered and left our things in a locker.

Later on, our instructor called Bea introduced herself and gave us a brief presentation of what we had to do. We went into a room that had the equipment and then explained three different experiments. Before starting the activity, she asked for two volunteers to help her prepare the material. We seated arround different tables in groups of six or seven students. And then Bea did a small revision of some concepts before start the experiments.

The first experiment was about chemiluminescence. Which consited of seeing an emission of light, as a result of a chemical change with luminol, bleach and sodium hydroxide.

After finishing the first experiment, we started an exothermic experiment that was very the reactions between different reagents, glycerin and potassium permanganate. The first thing we did was to place the reflective material in the middle of the table to facilitate the use of the material, we put the reagents first, than we added the crystals of potassium permanganate and then in the middle of the crystals we made a small hole to introduce the glycerin, with the help of the timer we could produce an exothermic reaction.

And the last chemical reaction was about casein coagulation. In the last experiment, we introduced ½  liter of milk. Then we warmed the milk until it boiled. When it cooled we added the vinegar and made the milk sour.We strained the milk and finally drained it and put it in the mold and let it dry. Finally we collected all the material that we had used. After that, we came back on to Plaça Catalunya by train except Júlia who left by car.

When we arrived at 15:00 everybody went to home.
