Differentiation Strategic grouping with strong speakers Have students explain aloud the observation plan after reading it Compare class data orally and on the spreadsheet Modifications Conduct the investigation as a demonstration if you are short on time or resources. Parts 1 and 2 of the Carbon TIME Growing Plants Video show the investigation and patterns of results. While we do not recommend this, if time is not available, students can watch the video instead of doing the investigation. Have students develop the experimental design on their own using the tools provided. For example, students may choose to set up a control treatment as a container with BTB and no plants. Put the “plants in the dark” container inside an opaque plastic bag instead of in a dark closet. Extending the Learning Have students compare photosynthesis rates between plants in the sun and plants under a grow light.
