This unit consists of five activities, all of which focus on the response of plant life-cycle events to climate change. Students participate in discussions, field observations, data collection and analyses, plant identification, seed dispersal... (View More)

This unit focuses on the impacts of climate change on humans. Students participate in activities using "Character Cards" (included with the unit). The cards introduce fictitious citizens who describe the local economic, social and political factors... (View More)

Students are introduced to the purposes, benefits and challenges of citizen science projects. Examples of historical and current projects are presented, and evidence is provided showing why human scientific analysis is sometimes better than computer... (View More)

Using the 5-E model, these lessons introduce planets, planetary systems, star types, exoplanets, transits, light curves, and the Planet Hunters citizen science project. Supplemental materials include data/image sheets. Next Generation Science... (View More)

This activity is designed to help building student understanding of how scientific theories can change over time. Science theories change in the face of new evidence. However, when new explanatory frameworks, or theories, are proposed to explain... (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)

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 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)

In this hands-on activity, students create a model soil profile in a two-liter beverage bottle, time the movement of water through different soils and observe the amount of water held in these soils. They observe the filtering ability of soils by... (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)
