Wrking in small grups, have students cnduct research n the Internet and/r lcate surces in the library fr pinins f thse wh believe in glbal warming versus thse wh d nt. Give them sufficient time t read the materials and encurage them t take ntes fr the debate. They may need additinal time utside the class perid t cmplete the readings. After students have cmpleted their research, make a T-chart n the bard with the headings Believers in Glbal Warming and Nn- Believers in Glbal Warming. Divide the class int tw grups: Believers and Nn-Believers. Have the tw grups meet t review their respective ntes and prepare fr the debate. Remind them that they shuld supprt their psitin with evidence drawn frm their research. Psitins and evidence shuld be scrutinized by the grup accrding t scientific merits, verifiability, weight f evidence, and influences by utside parties. Have the class cme tgether t begin the debate. Give each student sufficient time t express an pinin and t prvide supprtive evidence. Pse the fllwing questins t encurage the debate: Hw d we knw that glbal warming is ccurring when yesterday/last week/last mnth was cler than nrmal?
