II.KeyPoints&Difficulties

KeyPoints

InterconnectednessofLivingThings:

Alllivingthingsneedfood/water;dependoneachother(fish→birds→plants).

Humanactions(pollution,deforestation)disruptthisbalance.

Vocabulary&Grammar:

respect,connect,die,dead,follow—usedtodescribenaturerelationships.

Difficulties

Graspingplexecologicalconnections(e.g.,fish→birds→trees).

Accuratelyusingvocabularyinabstractcontexts(e.g.,“Natureisabalance—respectit”).

III.TeachingMethods

TaskBasedLearning(TBL):Throughsentenceordering,vocabularyfilling,passagepletion,andactionplancreation.

EcologySimulation:Roleplayingspeciesinteractions(e.g.,fish→birds)toshowconnections.

CollaborativeLearning:Groupworkforactionplanprojects,emphasizingpeerfeedbackonfeasibility.

IV.TeachingAids

CAI(ecosysteminteractionvideos,vocabularydefinitionanimations,actionplantemplates).

Textbook,worksheets,and“SpeciesConnectionCards”(with“fish,”“bird,”“tree”forroleplay).

V.TeachingProcedures

Step1:Warmup–LivingThingsDependence(5mins)

DiscusstheTHINKABOUTITquestions:

Doalllivingthingsdependononeanother?(E.g.,“Yes—treesgiveoxygentoanimals,animalsspreadseeds.”)
