I know that microscopes are used to see thing that are tiny for example a cell and there are a lot in the labs. It was invented by Zacharias Janssen in 1590.In the lab session i think that we are going to speak just in English and some exercise,maybe. Yes, i has been in a lab. I have seen a microscopes, but i don't remember what.

Homework 1

Have you ever gone to the lab? What did you do there?

- Yes. I use to go to the lab every Friday to do some exercises or experiments related with the theory.

We can look bacterias, microorganisms, etc, with the augmented lenses.

The basic parts of the microscope are the lenses, the eyepieces, the stage, the light and the base.

I know that the microscopes are used for look speciments, very little or thiny speciments. They are instruments that the scientifics used in the lab. We userd for look spaciments that we can't see a nackedeye.

-Tell us one thing we haven't said in class about micorscopes.

The first microscope to be developed was the optical microscope by Leeuenhoek. There are two types of microscopes: the optical microscope and the electron microscope, this one augment 1,000,000x.

-What do you think we will do in the lab sessions?

 I thing that we will do easy experiments in grups, and we will learn vocabulary specific.... I thing too that we will talk and learn things about plants, cells, animals, instruments of lab...

- Have you ever gone to the lab? 

What did you do there?Yes, I have gone to the lab. In ''hora B'' fridays last hour. When we have gone to the lab we have seen science films. I have done easy experiments with water, oil... We have done practices like open a heart, with lungs, and many other things...

The microscopes are objects that we use to do some experiments, see microscopy cells, Virus...

The diferents powers of microscopes, allow see things that humans can not see

TALK ABOUT CELLS:

The cell is the basic structural, functional and biological unit of all known livingorganisms. Cells are the smallest unit of life that can replicate independently, and are often called the "building blocks of life". The study of cells is called cell biology. The cell was discovered by Robert Hooke in 1665. The cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that all cells come from preexisting cells, that vital functions of an organism occur within cells, and that all cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.

The microscopes are objects that we use to see very tiny things, like cells. the cells were discovered for Roobert Hooke.

The microscoper are used in the labs, and they have got diferent powers: 4x, 10x, 40x...
