UNICELLULAR AND MULTICELLULAR CELLS (Natural Sciencie Year 5 Unit 1)

Along this topic we have learn about the living things and the cells. Today we want to learn a bit more about the organization of cells. If we focus our attention in the cells we can classify the organisms into MULTICELLULAR and UNICELLULAR.

Let's have a look to this video and at the end of the video in the group you have to create a definition about what a multicellular and an unicellurar is. 

UNICELLULAR ORGANISMS

Ameba, Picturepest, (CC BY 2.0)

Living things that are composed of a single cell are called unicellular organism. The single cell perform all the functions needed to live. 

REMIND QUESTION: What are the vital functions of a living thing? 

MULTICELLULAR ORGANISMS

Seaweeds, Mike Pennington, (CC BY-SA 2.0)

Living things that are composed of two or more cells are called multicellular organism. All the cells are arranged so that the organism can performed the vital  functions. 

• LEVEL 1: It is the single cell. 

• LEVEL 2: Tissues. They are a set of one type of cells which performs the same function. 

• LEVEL 3: Organs. The grouping together of a set of tissues which performs the same function. 

• LEVEL 4: System. Some organs that perform the same function are grouped together in a same system.

All the systems perform the ORGANISMS

Let's practise a bit more about Organization of Living Things using this video and the following test. 

• BBC: KS3 Betisize Science, Cells to system. 

Types of cells

 Muscle cells are elongated. These cells and the tissues can expand and contract. This allows muscle to move. 

Epithelial cells: These flat cells line certein area of the body such all the skin. They insulated the body and protect it. 

Nerves cells: They are star shaped with long extension or arms. These cells establish connections and then transmit information to all parts of the body

To sum up and internalise your knowledge along this lesson you are going to create a model explaining from the cells to the organism. Let's use plasticine to create the model and paper to label it. Take a picture of it to publish it. 

What do you have to do?  Create a model using plasticine and paper to reproduce this photo. 

STEP 1: Decide with your mates what you are going to represent. Let's investigate how it is and how to represent. 

STEP 2: Talk with your mates about the material you will need and how do you will organize to have it (plasticine, sticks, papers, and if it is posible a camera to take a photo)

STEP 3: Organize the group deciding who is going to do each things, who is going to create the cell, who the tissue, the organ,.....

STEP 4: Work on your part of the task, don't hesitate to ask for help to your mates in case it is necesary. 

STEP 5: Let's prepare the final model and take a picture and send it to your teacher. 

STEP 6: Each group will show the final product to the rest of the groups. 

• It will be esier for you to talk in front of your mates if you have a script to follow. The following sentences would be helpful for you. 
• Hello, we are........
• We are going to present you the .......levels of organization of the human body.
• The first level is the ......................
• All the .............together form the 2nd level which is..................
• The ............... together form the 3rd level which is the..............
• The ................., ..........................., .......................... are the different organs for the .......................... system. Explain your system, you can use your own information or you can have a look to page 14 and 15 of your book. 
• The ... system with the ... system, the ... system, the ... system, the ... system, the ... system, and the ...system form the HUMAN BODY.

CELLS (Natural Sciencie Year 5 Unit 1)

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?

Animal Cell Cross Section Model, Divinemercy, (CC BY-SA 3.0)

YES. We are talking about cells. 

All living things are made of cell. Cell is the smallest 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 difference 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. 

The characteristics of living things (Natural Sciencie Year 5 Unit 1)

Today we will start a new topic in our subject of Natural Science. We are going to learn and investigate about THE ORGANISATION OF LIVING THINGS. 

First of all we are going to start with the main characteristics of the living things. Let's have a look to the following video and try to identify the main characteristics of a living thing: What things make something to be a living thing?

Let's think on that question using a THINKING ROUTINE: Think - Pair - Share. 

VITAL FUNCTIONS

Nutrition:  Transform food into simple subtances: nutrients, and then get energy from them. Plants use the oxygen they take through leave to make their own food. Animals eat other living things. 

House for Giant Pandas, Michael Tyler (CC BY-SA 2.0)

Interaction: It is the ability of living things to sense the changes in the enviroment and react to them. 

Sun...flower, James Ryckwood (CC BY 2.0)

Reproduction: It enables living things to produce offspring similar to themselves. 

Baby dessert tortoise, U.S. Geological Survey

Let's  pratise your knowledge using this game. You can play in pairs, each one will run a colour of the game. 

THE SIZE OF LIVING THINGS

Macroscopic things: Living things that we can see with the naked eye. 

Big and little dog, Ellen Levy Finch, (CC SA-BY 3.0)

Microscopic things or microorganisms: They are living things that are so small that we cannot observe them even with a magnifying glass. To look at them we need a microscope.

Staphylococcus aureus bacteria escape, NIAID/RML  (CC0 1.0)

Let's do an investigation task about MACROSCOPIC and MICROSCOPIC living things. Each one of you will create a chart with a photo, the name of the living thing and the dimensions of the living things. We will make a big poster with all of them. 

• Microscopic: 
• Softschools: Bacteria Examples
• Wikipedia: List of viruses
• Macroscopic:
• Wikipedia: List of Herbivorous animals 
• List of Scientific Names of plants

Before finishing this part of the topic it would be great to think a bit about what you have learn. This part will be called de Learning Diary. Let's think a bit in these three questions and take some notes about your learning in your notebook.

• What have you learnt?
• How did you learn?
• Would you like to investigate or learn a bit more about any of these aspects?

CELLS (Science Y5 - Unit 1)

The characteristics of the living things are:

• They are born from other living things.
• They eat.
• They react to their environment.
• They grow.
• They reproduce.
• Finally, they die.

We have learnt this with the help of Mr.Bean and their frogs...
