Processes of Science

Mars, a Case Study

Activating Students’ Prior Knowledge

In pairs or small groups, have students look at photos of locations on Earth that show the effects of seasonal water: dry river beds, lake beds, and canyons. To apply the NGSS science and engineering practice of analyzing and interpreting data—specifically data from photos—students will observe, discuss, and list the evidence in the photos that indicates that water was once present. Have students review the photographic evidence of the impact of water and make a chart of the similarities and differences in the photos. (For example, students might notice patterns or placements of rocks that suggest they were moved by water. They might observe soil or rock erosion that suggests a current.)
