Animal Kingdom

Hi!!!

I leave you the videos that we have watched this morning. You can watch them again as they will help you study and understand things better.

Investigation Projects

We have already started our Investigation Projects!!

We are investigating about different animals (each group has chosen an animal). As you have to find out information and answer the questions that you have proposed, I propose you to have a look at the Britannica Kids encyclopaedia. We don't have full access to all the content, but it includes links to interesting websites and articles!!

You can also look for information on the following pages:

- SIMPLE ENGLISH WIKIPEDIA


- FACT MONSTER

- KIDS.NET


Remeber that you have all this links at the right part of the blog!!

Levels of organization

As you know, organisms can be:

- Unicelular if they are formed by only one cell (Prokaryote cells)

- Multicellular if they are formed by more than one cell (Eukaryote cells)

 In multicellular organisms, such as animals and plants, groups of cells work together to carry out different functions. These are called levels of organization. 

• A group of cells of the same type and with the same function form a tissue.
• When tissues join together they form an organ.
• A group of different organs working together makes up a system.
•  Finally, different systems join together to make an organism.

So, an organism is made up of systems; a system is made up of organs; an organ is made up of tissues and a tissue is made up od cells.

ORGANISM > SYSTEMS > ORGANS > TISSUES > CELLS
