My first lab experience, according to Blanca

In my opinion, my first experiment in all my life was wonderful!

We went to the lab with our teachers (Rafa and Mónica) and we learned many things about the scientific method. For example: the scientists always use the same instrument not to make mistakes. The most interesting was the experiment and I think that a lost of people think like me.

I liked the entire experiment, but the idea of creating a scientific report is no fun!

For a first experiment, I think that I did very well with my partner, Manuel. This is what we did to measure the density of milk:

We have a beaker with 250 ml of milk.


1.- We measure the test tube without milk= 138 g.

2.- We put milk in the test tube (20 ml in volume)

3.- We measure it= 156.1- 138 (that is the weight of the empty test tube) = 18.1 g

With those measurements, we calculated the density using the formula.

I liked this experiment very very much and I wish that everybody feels the same way!!!

1º ESO experiences first lab visit

Yesterday, students from both Natural Science classes went to the laboratory to study, first hand, how to follow scientific protocols while performing lab experiments. Everyone was excited and truly concentrated on their task. By the way, they calculated the density of a particular liquid: milk. Now, it is their responsibility to produce a quality lab report, explaining their findings and how they got them.

Good luck to you guys, and I leave you with some pictures. Enjoy
