Microscope observation of cheek cells

I add some images to help you with the experiment report about microscope observation of cheek cells.

First we used a clean cotton swab to get the cells, then we used the methylene blue solution to give color to the cells, then we used the microscope with differents magnifications to study the sample

this is a pointer that we use to point out things

we could see something like this:

Super Size Me

Super Size Me

As we could learn in the first and second units, talking about different biomolecules and their function in the human body, and also all the information that we received from the activity about nutrition that we have had on the high school, we know that is really important to have a good diet to be healthy.

See the documentary "Super size Me", write a short report where you describe what happen in the film, the real problems that a bad diet can cause in our organisms and the importance of have a good diet.

There is something wrong with it, so maybe you need to see the first and last part in spanish or look for it in other places
