The document discusses different forms of energy and how living things obtain energy. It explains that plants obtain energy from sunlight through photosynthesis to produce food, while animals obtain energy by eating food or other animals. It notes that all living and non-living things require energy to function, whether it is food, fuel, electricity, heat, light, sound or other forms of energy. The document also provides examples of activities teachers can do to demonstrate different types of energy to students.

1. Science is nothing but: observing, experimenting and inferring ______ observing experimenting inferring Do you remember ? So let’s think about it…….. How things happen?

2. It is all about energy ! How Things Happen? Energy

3. H ow T hings H appen? Why do you eat food? You eat because you have to get energy for living. You need energy for walking, talking, running, playing, and doing every kind of work. Animals and plants also need energy. Animal take their kind of food. Do plants eat food too? No, they do not. They do not eat like animals. Instead they make their food using the sunlight energy. Energy

4. How Things Happen We have to eat to get energy Energy

5. E NERGY F ROM F OOD

6. Energy All living things need food Animals, plants and human beings need energy to do work

7. day night sun light sugar carbon dioxide water PLANTS MAKE FOOD in sunlight This whole process is called photosynthesis. Energy

8. There are different ways in which animals obtain their food . But they all need food to get energy. Food is the fuel for the living engine ! In an automobile fuel is burned to get energy in order to get it moving; Much like the same food is burned in our bodies; By the process of burning we mean stepwise chemical breakdown of food in order to release energy ENERGY FROM FOOD Energy

9. Energy

10. What did you see in the previous slide? Sun is the ultimate source of energy. Plants make food in sunlight from chlorophyll using salts and water from soil. Many animals depend upon plants for food. We also, directly or indirectly, depend upon plants for our food. Energy

11. Things get moving or working when energy is supplied to them. Fuel, electricity, wind, heat, light, sound are different kinds of energy

12. Objectives After reading this lesson The children will know that: Energy

13. Energy is the Key word Animals have to eat food Plants need to have sunlight, water and minerals to make food Machines need fuel Every moving thing needs energy Kinds of energy: light, heat , electrical , mechanical , chemical, sound , muscular.

14. heat Energy chemical light heat motion electrical potential muscular mechanical Energy

15. Activities Many easy activities can be performed with this kind of lesson. First ask questions in order to revise the lesson thoroughly. Why do living things need energy? What 2 types of energy we get from sun? What do plants do for their food? Why do we need to have petrol or gas for cars? How is a bulb lighted? How does a sail boat move? Energy

16. Hints for Activities Light a candle and ask children what is happening. (Heat and light are produced) Bring battery operated toys, and show the children that they don’t work if you take out the battery. Drop a ball on the ground, or roll it on the table Pick up some pins by a magnet. Make a child stand in front of a fan with a paper in hand. Make the children sing National Anthem. Ring a bell. Tell them sound is also a kind of energy. Hold the hand of a child tightly, tell them it is the muscular energy. Energy
