Earth as a System
Seasons and Phenology
- Seasons and Phenology: Summary
- Seasons and Phenology: Introduction
- S1: What Can We Learn About Our Seasons? - Students develop a qualitative understanding of the characteristics and patterns of seasons and highlight the relationship of seasons to physical, biological and cultural markers.
- S2: What Are Some Factors That Affect Seasonal Patterns? - Students use GLOBE data and graphing tools to compare the influence of latitude, elevation, and geography on seasonal patterns.
- S3: How Do Seasonal Temperature Patterns Vary Among Different Regions of the World? ** - Students use GLOBE visualizations to display student data on maps and to learn about seasonal changes in regional and global temperature patterns.
- S4: Modeling the Reasons for Seasonal Change - Students use color visualizations and a 3-D paper model of the Earth to explore the causes of seasons, with a focus on Earth's tilt and its spherical shape.
- S5: Seasonal Change on Land and Water ** - Students use visualizations to compare the effects of incoming solar energy in the two hemispheres, furthering their understanding of seasonal change and climatic effects of land and water.
- P1: Green-up Cards - Students participate in a preparatory activity that will help them identify green-up progression in their local plants and this activity also introduces the idea of spatial scale related to plant observations.
- P2: A Sneak Preview of Budburst - Students learn what to look for during budburst by observing variations in timing and appearance of leaves of different local plant species.
- P3: A First Look at Phenology - Students observe and classify local plants based on their patterns of change other than growth.
- P4: A Beginning Look at Photosynthesis - Students learn about plant response to light by setting up simple investigations in the classroom.
- P5: Investigating Leaf Pigments - Students learn about plant pigmentation and photosynthesis while conducting simple investigations to demonstrate the presence of pigments other than chlorophyll in leaves.
- P6: Global Patterns in Green-up and Green-down ** - Students use visualizations and graphs to investigate the annual cycles of plant growth and decline associated with various land cover types.
- P7: Temperature and Precipitation as Limiting Factors in Ecosystems ** - Students learn about the physical factors that limit the growth of vegetative ecosystems by correlating graphs of vegetation vigor, temperature, and precipitation.
Exploring the Connections
- Exploring the Connections: Summary
- Exploring the Connections: Introduction
- LC1: Connecting the parts of the study site - Students visit the study site, observe the different components of the Earth system and predict how they are connected to and affect each other.
- LC2: Representing the study site in a diagram - Students, either individually or in small groups, use their knowledge of their study site develop a diagram that illustrates the most important connections between the different components of the Earth system.
- LC3: Using graphs to show connections - Students use GLOBE student data to explore, understand, and communicate the connections between the components of the Earth system exist at the study site they are investigating.
- LC4: Diagramming the study site for others - Students compare and contrast the diagrams of their study site developed by individuals or small groups, and develop a class diagram of their study site that best communicates the most important connections between the components of the Earth system that exist there.
- LC5: Comparing the study site to one in another region - Students compare and contrast diagram of their study site with a diagram developed for a region that is biogeographically different than their own.
- RC1: Defining regional boundaries - Students broaden their understanding of the Earth system by expanding their view of the Earth system from the local site to a regional system by identifying the boundaries of a regional Earth system.
- RC2: Effects of inputs and outputs on a region - Students examine the inputs and outputs of a regional scale Earth system and predict what would happen to that system if any of those inputs or outputs were changed.
- GC1: Your regional and global connection - Using global scale maps of winds and ocean currents students predict what region(s) in other parts of the world might be affected by their region.
- GC2: Components of the earth system working together - Using data about the components of the Earth system at the global scale, students discuss how the components interact to form the Earth system as a whole and use the water cycle to explore this in more detail.
