UNIT 1. LIVING BEING
C.E.I.P. SANTA ANA (Madridejos)TION:
There are many things around us. Some of them are alive and some are not. Look at the pictures and say the differences between them. Could you make a mind map to organize them?
1. WHAT DO YOU THINK?
What animals are endangered? What plants? Why? Is there anything we can do to help them? How?
2. WHAT ISALIVING BEING?
How do you know if something is living? What objects are made from living things? In nature we can find two types of things: non living things (stones, rocks, minerals) and living things (animals, plants…).
Living beings need food, water and air to live and grow. They react to things. Living beings perform the vital functions. Non-living things don’t perform the vital functions.
The vital functions are nutrition, interaction and reproduction.
NUTRITION. Living beings get oxygen and nutrients, that they use to get energy and grow. Later they expel waste products.
INTERACTION. Living beings detect changes (temperature, sounds) in the environment and they react.
LEARNING SITUA-
REPRODUCTION is the process in which living beings produce more beings similar to them-
1. Guess the vital function:
We come from other living beings: We react to things that happen: We need food to live:
2. Name three living things and three non living things.
Let’s play.

3. CLASSIFICATION OF LIVING THINGS
What things do you classify in your house?
Say: animal or plant.
Sea sponges look like plants, but they are animals. Is this an animal or a plant?
Classifying living beings means grouping similarones together. We choose specific features to help us classify. For example: Do they have skeleton or not? Do they perform photosynthesis?
We can classify all beings in five big groups or five kingdoms.
4. FIVE KINGDOMS
Each kingdom is formed by living beings with similar characteristics.
FIVE KINGDOMS are: Monera (or bacteria), Protoctista, Fungi, Plants, and Animals
4.1. MONERA KINGDOM (or bacteria). They are very small. They can live everywhere, even inside our bodies. There are helpful bacterias (in our intestine…) and harmful bacterias that produce many infections and dis- eases.
4.2. PROTOCTISTA KINGDOM. They are small. They live in the water in colonies. Algae make their own food like plants, the rest of them eat other living things. Protozoa don’t move. Amoebas can move.
1. Odd one out:
Algae - bacteria - amoeba
Animal Plant Monera Fungi Nutrition Protoctista
2. True/false: Yeast and mould are monerans. Some bacteria are good for us.
3. How do you differentiate a plant from an animal?
4. Where can bacterias live?
5. Have you ever had a bacteria inside your body?

4.3. FUNGI KINGDOM.
Fungi don’t make their own food. They live in damp places. We eat some types of fungi, such as mushrooms. Mould and yeast are also fungi.
Why are plantsdifferentfromfungi?
In which places can we see mould?
4.4. PLANT KINGDOM.
Plants produce their own food through the photosynthesis. They get energy from the Sun. They can’t move from the soil. There are two groups: Without flowers like moss and fern (they reproduce themselves by spores).
With flowers, like lemon, orange, almond trees, rose bush
4.5. ANIMAL KINGDOM.
They can move around. They eat other living things because they can’t produce their own food. They need food, water and oxygen. There are two groups: vertebrates and invertebrates.
Which kingdoms do they belong to?

What is biodiversity?
Scientists have discovered more than two million different species, but there are still many more to discover. The enormous variety of living things is called biodiversity.
Our planet is ideal for life because it has light, water and air.
Living things of the same species which live in the same place are called a population, like a fox population in a forest.
All the populations are a community.
In what ways are plants and animals important to each other?
