Characteristics of living thingsPre-requisite knowledge/skills:Learning outcomes: The students will be able to:• Identify the seven characteristics of living things• Differentiate between living and non-living• Infer that living things have modifications according to their habits, need and habitat.Materials / resources required: Chart, fact sheetEssential Unit Questions:• What are the characteristics of living things• What are the criteria of classification of plants and animals?Time Class setting/ResourcesLearning Sequence10mins Whole class Introduction:Have the students to take out their home assignment andask if any one faced any difficulty. Have the students readout their answers and discuss them.Show to the students a few samples of living and non-livingthings and ask them to tell the differences between them.Solicit the reply that they can be classified as living or non-living, natural or man-made.Ask them what they understand by living and non-livingthings by giving examples.20 minWhole classdiscussion/Groupactivity/half chartpaperPhase 1: Instructional ProcessTell the students that the following activity is a groupwork. Each group has to write down what they think arethe characteristics of living things.Ask how can they differentiate between living and non-living things?Divide the class into groups.Phase 2:After the groups have finished their work ask them to readKavita Grover Page 2
out their answers and using mind mapping tool given asreference write on the blackboard the seven maincharacteristics of living thingsAsk students:What are the different characteristics of livings thing?Conclude by saying that the main differences are:Movement, Respiration, Sensitivity, Growth, Nutrition,Reproduction, Excretion, and.Let’s now take up each characteristic and discuss about it.Movement:• Ask the students what they understand bymovement.• Why do living things move?• How do insects, birds, fishes, etc move?• Do plants also move?• How do animals move?• Why do they move?Respiration:• What is respiration?• Do plants also respire/how do plants breathe?• How do they breathe?• How do animals breathe? (Land, water, worms andinsects)Sensitivity:• What do you understand by sensitivity?• When you prick your hand what do you do?• When you see some insect near your eye what doyou do?• What happens when you feel very cold?• What are the different sense organs?• Do you think plants are also sensitive?Growth:• Ask: What is growth?• Do all living things grow?• How do plants grow?• Give an example?• Do animals show growth?Reproduction:• What is reproduction?• Why do living things reproduce?• How do plants reproduce?Kavita Grover Page 3
• Where are seeds produced?• How do animals reproduce?Excretion:• What is excretion?• Why do living things excrete?• How do animals excrete?• What do they excrete?• Do plants have any organs for excretion?Nutrition:• What is nutrition?• Why do living thing need food?• How do animals produce food?• How do plants produce food?• Why are leaves green?• Name the process through which plants make theirown food?Tell the students that living thing must have all the MRSGREN characteristics to be classified as living.10 minsGroupwork./enlarged copyof the incompletemind map/fact sheetPhase 3:After the mind mapping on the BB, the students have to readthe fact sheet and complete the in-complete mind map.10 minsPaired work/worksheetPhase 4:After the group the students will work in pair and completethe table on the work sheet.5minsWhole class/worksheetPhase 4:Feedback:Whole class Closure:Ask the students:• What are the characteristics of living things• What are the differences between plants and animalsHome work worksheetKavita Grover Page 4
Fact SheetCharacteristics of living things1. MOVEMENTMost living things move. Living things move in order to survive.Plants move but do not move their position. They are able to moveparts of themselves.Plants move their roots towards water and towards the centre of the earth. They move theirstems and leaves towards light.Animals move to keep themselves safe and to look for food.Some animals move on land, air and water.2. RESPIRATIONAll living things need oxygen to stay alive. They use oxygen to turnfood into energy.To obtain oxygen from the air, animals and plants exchange gasesbetween themselves and their surroundings.Green plants exchange gases with their surroundings through holes inthe under-surface of their leaves. These holes are called stomata.Animals have different organs of breathing depending in the habitat they stay..3. SENSITIVITY:All living things react to stimuli. This means they are sensitive to changes in theirsurroundings and react to them.All animals are sensitive to what is happening around them.Example we shiver when it is cold. We withdraw our hand whenwe touch a hot thing. Some animals have complicated nervoussystems and brains. They have a sense of taste, sight, hearing,touch and smell.Kavita Grover Page 6Fishes, which live under water,obtain oxygen using gillsWorms get oxygen through thesurface of their skin, and insects usebreathing tubes called trachea.Most land animals havelungs.
Plants also respond to stimuli, but in a different way to animals. Some plants turn towardsthe sunlight. Their roots sense and move towards water. The sun flower turns its facetowards the sun, during the day and droop when the sun has set.4. GROWTHAll living things grow. This means they increase their size. They can grow taller. They cangrow wider.5. REPRODUCTIONAll living things reproduce, this means that they make copies of themselves before they die..Plants which have flowers reproduce from seeds. The new seedlings then grow into plants.Other plants grow from spores and cuttings.6. EXCRETIONLiving things have to remove the harmful effects of waste products from their body.Some of these waste products are: carbon-di oxide, nitrogen and water..Kavita Grover Page 7Plants grow taller and wider. Seedlings grow intobigger plants. Plants increase their size in alldirections. And their shape is changing all thetime.Baby animals grow into adult animals.Animals also grow taller and wider, butcan only increase their size in a definiteshape.Some animals reproduce by laying eggs.Frogs, snakes most fish and insects lay eggs.When the young ones of these animals hatchthey have to take care of themselvesMammals like dogs, cow, rabbits etc give birth toyou to young ones. The mother suckles the youngones with her milk. Man is also a mammal.Animals, such as humans, cats, dogs, removethe harmful effects of the gas carbon dioxideby breathing out. They also breathe outwater vapor. The main organs which removenitrogen waste from the body are thekidneys
Plants also produce waste nitrogen, but only in small amounts. They do not possess organsto remove it, so store it in some of their cells after they have turned it into a harmlesssubstance. Some harmful wastes are excreted from the bark of the tree.7. NUTRITIONAll living things feed. They feed to supply themselves with energy.Most green plants make their own food. They make their foodfrom the simple raw materials carbon dioxide and water. Thegreen color (chlorophyll) in the leaves together with sunlightallows carbon dioxide and water to be combined. This processis called photosynthesis.Kavita Grover Page 8Animals do not maketheir own food. Theyfeed on plants, otheranimals, and on deadwaste.
