Plants grow and reproduce.

Look at the pictures of these fruits. Does these fruits have seeds. If the fruits have seeds, what can you do with the seeds? Do you eat the seeds? Why do plants have seeds?


Before a plant produces fruit it will produce flowers. The flowers will develop into fruits and seeds. The seed can be planted to produce a new plant.


Animals grow 2 (Butterfly)

Butterflies too go through various stages of development. Just like the tadpole a butterfly begins its life in an egg. When the egg hatches a little caterpillar will hatch. The caterpillar will grow until it reaches the pupa stage. After a week the butterfly will come out from the pupa.

Look at the video clip below and observe the life cycle of a butterfly.



Question: In what way is the baby butterfly (caterpillar) different from the butterfly?

Animals grow 1 (FROG)

Frogs have different stages of development. The first stage is the egg stage. After which the eggs will hatch and the little tadpoles will come out. The tadpoles will grow and have the behind legs before the front legs appear. Then the tails will disappear before they become full grown frogs.



Question: In what way is the baby frog (tadpole) different from the adult frog?

Animal food.

Look at the animals in the video clips below. Observe what they eat.











Animals

Do you have a pet? 

How do you keep your pet?
Who gives it food? 
Pets are animals. 
All animals have to eat food. 
They also need air and water to stay alive.  
Look at the pictures what do these animals need are the food of these animals the same? 








Discuss this with your friends. 

We grow!




Look at the pictures above. These are the pictures of the same person. Is the picture different. If it is different, why is it different? How can the same person be different? Think about it.

As a person grows. The individual will experience changes in the length of the hands, feet and their body size. Other than that their faces will also change, but it will always be the same person from childhood to adulthood.

The Food Pyramid.

Whatever we eat everyday, we must make sure that the food is suitable for our bodies. That is why we have the food pyramid to guide us in what we can eat more and what we must eat less. It is important that we eat healthy food so that we will be healthy and strong.
In the food pyramid we have cereals like rice, corn, wheat and other grains at the bottom of the pyramid. These food are important as they give us energy and
Then we have fruits, vegetable,
Then we have Meat and milk etc.  - help to grow etc.

Sugar,  sweets, fats -
The food that we eat less are unhealthy so we must eat it less.

View the video below to understand it better.


The need of food

In the first entry you have learnt about living things and non living thing. Now think about yourself. Are you a living thing  or non-living thing - why? You can discuss it with your friends and tell them the reason.

Look at the pictures what do you think happened to them?
Can the same thing happen to you? Think about it. Are the people in the picture living beings. Why? What will happen to them if they did not have food.

How long did the people in these pictures not eat?




What will happen to them if they continue not eating?



Yes they will die.

Living things and non living things.

There are many things around us. (Give examples.) These objects can be divided into two different namely living things and non-living things. Living things breath, grow, move, need food, need water, can produce young, while non-living things do not do that. Look around you can you see the living things and non-living things. Which is more living things and non-living things. Can you group these objects into the two groups.

Just to think: Look at the plants. Are they living or no living things? Why?

Look at these videos - can you identify the living and non-living things?






Conclusion: Living thing can breath, move, need food, need water, produce young.
