8 slide PowerPoint. Consists of 13 images taken in chronological order of two people eating dinner. You can print the images. Students put the images in chronological order and can make observations and inferences about what they see. I usually have the students make three columns on a large piece of paper. One for the picture, one for the observation and a third column for inferences. Print out large color copies for manipulation but you may want to use smaller B&W pictures for student activity.
