Bird - Eggs with shell coveringFrog - Eggs are thick, slimy and having bad smellSpider - kept in a bag underneath its bodyFish - keep their young in their mouthsSnake, Tiger - attack in order to protect their eggs Turtle - hide their eggsKangaroo - carry their young in their pouches Elephant - stay in herds

3.1 Food ChainAnimals and the food they eatClassify animals into herbivore, carnivore and omnivore.Producer Consumer Construct food chainGreen plant obtain energy fromthe sun to make food. GreenPlant as a producerHerbivore :Animals that eat plants only.e.g.: cow, goat, deerCarnivore:Animals that eat other animals.e.g.: tiger, lionOmnivore:Animals that eat plants and other animalsAnimals that eat plantor other animals are called consumers.

The food relationshipamong living things can be shown bya food chain.To construct food chain It must start with plant as a producer.In a food chainthe arrow

means eaten by

All living things need food to survive.Green plant can make theirown food. However animals cannot make their own make their own food.

INVESTIGATING FORCE AND ENERGYENERGY1.1 The Uses of EnergyWhy energy is needed?- by living things to carry out life processes. Ex : moving, breathing, growingThe Sources of EnergySun- main source of energy - produces light and heatFood- food contains stored energyWind- Moving air - Used to pump water, drive small sawmills - to move, boil, melt, or bounce non-living thingsFuelBatteries- wood, coal, petroleum, natural gas- device that generated electrical energy from chemical energyWater- moving or falling water produce energy
