Here we have the green tables group of ESO2.
They have already started to attend the laboratory sessions where we perform experiments in English. We will learn about safety, the use of the basic laboratory equipment and also about separation techniques.
We have been learning about density and how to measure density of irregular solids,. We have also been able to identify solutions with different salinity thanks to their different density.
This term, a new group of students are going to the lab three times a week.
So far we have learned the safety rules to be followed in the lab, the tools and equipment that we use in the lab. We have studied and experimented with the magnitudes mass, volume, density using the scales, graduated cylinders, droppers and beakers.
Last week we had to measure the volume of one drop of water. Do you know how many drops of water there are in 1 mL of water? Some students guessed 6 drops, others 15 or 20 drops. Who was right?
Come to the lab and try yourself!
This week we are doing posters about the mixture separation techniques and next week we are going to start the section: MY OWN EXPERIMENT.
