The first section of the guide includes a detailed narrative of scientific background, which may need to be interpreted or adapted for student use. For example, students study fish scales to identify changes in environmental conditions experienced by a fish. They create a simulated sediment bed with pollen grains and take core samples and analyze them. They also expose soil samples to sunlight to study the relationship between heat, evaporation, and erosion. In other activities, they examine tree rings, and they observe phase changes in water due to heating and cooling and relate these changes to climate zones.
Several activities promote the concept of change over time.
The third section of the guide includes tips on designing science lessons that employ scientific inquiry and 40 ideas for extension activities.
