4年级科学教学大纲

TermOne

Unit1 (Moving and growing)

·Know that humans(andsome other animals) have bonyskeletons inside their bodies,andraise questions about differentbonyskeletons

·Make and record relevant observations ofbones andskeletons

·Make observations andcomparisonsof relevant features

·Know that human skeletons are internal and grow as humansgrow

·Identify a question to makea predictionthat can be tested

·Decide precisely what bodymeasurementto make, and make thesemeasurements

·Use barchartsor pictograms to present measurements

·Say what the evidence shows andwhether it supportsthe prediction

·Know that theskeleton supportsthe body

·Know that animals withskeletonshave muscles attached to thebones

·Know that amuscle has to contract (shorten) to make abone move

·Know that muscles act in pairs

·Know that when someoneis exercising or moving fast, the muscles work hard

·Make observations andcomparisons relatingto exercise andrest

Unit2 (Keeping warm)

·Know that thesenseof touch is not an accurateway of judging temperature

·Know how to use a thermometer tomake careful measurements of temperature usingstandardmeasures

·Know that temperature is a measure of how hot or howcold things are, and that somethinghotwill cool down and that somethingcold will warm up untilit is the same temperature as itssurroundings

·Explain temperature andtemperature changes usingscientific knowledge andunderstanding

·Use ITto collect, store andretrieve temperatures and to explain trends andpatterns inresults in terms of scientific knowledge andunderstanding

·Turn an ideaabout howto keep things cold into a form that can be investigated

·Decidewhatevidence to collect

·Make a tableand record results in it

·Draw conclusionsfrom theirresults

·Conductafairtest

·Collect relevant evidence and use it appropriately whendrawing a conclusion

·Begin to turnideas into a form that can be investigated

·Use thermometers to makecareful measurementsof temperature

·Identify and suggest explanationsfor patterns and trends in resultsand use these results todrawconclusions

·Know that metals are not goodthermal insulators but that wood andplastics aregood thermalinsulators

·Know that materialssuchas metals, whichare good electricalconductors, areoften good thermal conductors

·Recognize a range of usesof thermal insulators

TermTwo

Unit3 (Friction)

·Use a forcemeter carefullyto measure forces

·Know that ‘newton’isthe unit of force

·Know that there is a force betweenan object and a surfacewhichmayprevent the object moving

·Decidewhatevidence to collect

·Predict whatwill happenand plan a fairtest

·Make and record careful measurementsand present them in a barchart

·Relate the results to the prediction

·Explain conclusions in terms of the roughnessor smoothnessof the surfaces

·Plan a fair test as independently as possible

·Try and explain the resultsin terms of friction

·Know that when two moving surfacesare in contact, the force between them is called friction

·Know that friction can be useful

·Know that water resistanceslowsdownan object moving through water

·Explain whatevidence needsto be collected and decidewhether the test is fair

·Identify trends in results and drawconclusions explaining thesein termsof the force betweenthe object and the water

·Know that airresistance isa force that slows downobjects moving throughair

Unit 4 (Solids,liquids and how they can be separated)

·Identify solids and liquids

·Know that there are liquidsotherthanwater

·Makecarefulobservationsandmeasurements of volume, recording them in tablesand using them to draw conclusions

·Know that liquids do not change in volume when theyare poured into a different container

·Know that solids consistingofvery small pieces behave like liquidsin some ways

·Know that solids can be mixed togetherand it is often possibleto get the originalmaterials back

·Choose appropriate apparatus forseparatinga mixture ofsolids

·Know that changes occurwhen somesolids are added to water

·Makecarefulobservationsandrecordresults in tables and then make comparisons

·Know that thesame materialcan exist as both solid and liquid

·Know that liquidscan bechanged to a solid by cooling, and this is known as freezing or solidifying

·Know that a solid can be changed to a liquid by heating and this isknownas melting

·Know that different solids meltat different temperatures

·Know that melting and solidifying or freezing are changes that can be reversed and thatthey are the reverse of each other

TermThree

Unit5 (Habitats)

·Identify different types of habitat

·Know that different animalsare found indifferent habitats

·Make predictions of organisms that will be found in a habitat

·Observe theconditionsin a local habitatand make a record of the animals found

·Know that animals are suited to the environments that they are found in

·Group organismsaccording to observablefeatures

·Use keys to identify local plants or animals

·Identify the food sourcesof different animals in different habitats

·Pose questions aboutorganisms and their habitats, and make predictions

·Decidewhatevidence to collect and to design a fairtest

·Makereliableobservationsof organisms

·Indicatewhether theirpredictions are valid and explainfindings in scientific terms

·Identify the structure of a food chain ofa specific habitat

·Know that animals aresuited to the habitat they are found in

·Know that most food chainsstart with a green plant

·Recognize ways in which living things and the environmentneed protection
