Students explore how mathematical descriptions of the physical environment can be fine-tuned through testing using data. In this activity, student teams obtain satellite data measuring the Earth's albedo, and then input this data into a... (View More)

Students observe cloud type and coverage and weather conditions over a five-day period and correlate these observations. Students make and test predictions using these observations. This is a learning activity associated with the Atmosphere chapter... (View More)

This is an activity about modeling and the scientific process. Learners will discuss the models they created in the previous three activities as models of forces that shape the surface of planets, and talk about the similarities and differences... (View More)

In this hands-on activity, students conduct bottle experiments to learn about the conditions that best facilitate the decomposition of organic material in soil. In the lab, they observe changes in the decomposition of vegetable scraps by varying the... (View More)

In this activity, students quantitatively evaluate the accuracy of a classification and understand a simple difference/error matrix. Students sort birds into three possible classes based on each bird’s beak: carnivores (meat eaters), herbivores... (View More)

In this activity, students learn about hierarchical classification systems and create their own classification system for leaves they collect in the field. They learn about the key characteristics for classification systems and see that there are... (View More)

In this activity, student teams design and conduct a scientific investigation in which they explore the conditions necessary for life. They conduct observations of environmental conditions both indoor and outdoor, and determine the range of... (View More)

In this laboratory activity, students analyze soil samples from their homes to identify soil properties and learn about soil classification. Soils sampled by students from different environments are compared, and students ask questions about the... (View More)
