The organisation of the human body

During the previous lessons we have learnt that the organs are joined with other organs which have the same function creating a SYSTEM. All the systems together perfom the BODY.

Today we are going to work on the organization of the human body and the explanation of the different systems of it. But it is not going to be a normal lesson in which the teacher talks and you just listen.

This time you are going to prepare the lesson and explained to your classmates. In your groups you are going to decide a SYSTEM, behind all these paragraphs you will find information about it,

FOLLOW THE STEPS IN ORDER TO SUCESS.

STEP 1: Decide in each group which system you are going to work on.

STEP 2: Look for all the given information of it, if you need more feel free to look for it in the net.

STEP 3: Design your poster. It should have:

1. Title with the system.
2. A big picture of the system.
3. What vital fuction it covers.
4. How the system do it (let's look at your class book)
5. Label the main parts of it.

STEP 4: Prepare a speech to show it to your mates. Remember you will be their teacher about it so please, try to be clear and precise. Your teacher should check it before the final exhibition. 

SCRIPT:

• Hi! Our names are (your names).
• We are going to present the (name of the system) system.
• As you can see this is a big picture about the (name of the system) system.
• The vital function which it covers are ...
• The (name of the system) system works ...
• The main parts of the (name of the system) system are ...
• I hope you have understood.
• Thanks for your attention.
• Goodbye.

We are learning about living things. In the last lessons we were talking about The Characteristics of Living Things. Just take three minutes to remind and share your learning with your group mates and your class.

Now we are going to take a step forward in the organization of living things we are going to learn about the smallest part in a living thing. Do you know what it is?

Let's have a look to this video and think on it using a THINKING ROUTINE: I see - I think - I wonder

DO YOU KNOW NOW WHAT IT IS THE SMALLEST PART OF A LIVING THING?

YES. We are talking about cells. 

All living things are made of cell. Cell is the samllest unit of live. It is a living thing because it performs the three vital functions: nutrition, interaction and reproduction. 

Let's have a look to the following video and try to answer these questions:

• What parts of the cell do you hear at the song?
• What are the function of these parts?
• Are there any diffeence between an animal cell and the plant cell?

All the cells have:

• Nucleus: contains the material necessary to reproduce the cell and to assign the activities of the cell.
• Cytoplasm: is inside the cell, It is a viscous liquid qich the organelles float in. 
• Organelles: perform various cell funtions, such us manufacturing chemicals and obtaining energy.
• Cell membrane is the outer shell of the cell and takes part in the interaction fuction. 

The plant cells have:

• Cell wall: is a rigid structures that surrounds the cell membrane and protects the cell. 
• Chloroplast: are green organelles that capture light and produce nutrients.

LET'S INVESTIGATE: why do the plant cells have chloroplast?

The following website will help you:

• Biology4kids: Chloroplast

The following games will help you to fix your knowledge about cells. 

• Shephard Software's: Cell games. 

Now it is time to fix your learning in your notebook. Let's draw the two cells, plant and animal ones, label them and write down the differences between them.
