Do any of your students struggle with the scientific and mathematical concepts underlying a lab investigation or to articulate conclusions based on their data? If so, try enhancing their higher-order thinking skills by explicitly linking science and math together. Before students collect and graph their actual data, ask them to predict what they think their data will look like and to sketch a graph of their prediction. Asking students to graph their prediction before they begin a lab investigation helps them construct a theoretical context for the investigation.
