Extension:If you want to take this experiment another step, try testing the individual leaves of a plant. Place bluecobalt chloride paper on the underside of one leaf and the upper side of another leaf. The cobalt chloridepaper place on the underside of the leaf turns pink but the blue cobalt chloride paper on the upper side ofthe leaf remains blue.Get students to create hypothesis about what they expect the results will be before you conduct thisextension demonstration. Then get students to suggest possible explanations for the observed results.Web Links:http://www.funsci.com/fun3_en/exper1/exper1.htmhttp://www.skoool.ie/skoool/homeworkzone.asp?id=255http://www.ehow.com/list_7433793_plant-respiration-experiments.htmlhttp://www.oocities.org/hkbiology/respirationexperiment.htm4The NCE-MSTL does not claim ownership rights to the images on this activity sheet.
