Students learn about plant response to light by setting up simple investigations in the classroom.
Biosphere, Green-Up / Green-Down, Lilac Phenology, Phenological Gardens Learning Activities
Students discover that soil properties such as moisture and temperature can vary considerably across a single landscape.
Soil Characterization Learning Activities
Pedosphere (Soil) Learning Activities
Students learn what to look for during budburst by observing variations in timing and appearance of leaves of different local plant species.
Biosphere, Green-Up / Green-Down Learning Activities
Use this flowchart to help you decide which Introductory Activities are appropriate for your classroom. For more information, see the Carbon Cycle Introduction eTraining .
Biosphere, Carbon Cycle Learning Activities
Students explore the relationship between circumference and diameter, learn that circumference is measured at 1.35 m from the tree base, and how to accurately measure trees in the field.
Biosphere, Carbon Cycle Protocol Instructions, Supporting Protocols
Select a Carbon Cycle Site. Determine if your site is STANDARD (accessible area of at least 225m2 of contiguous vegetation ) or NON-STANDARD (an area with some vegetation and some human interference, i.e. a local park, city block, or the school area itself). *This protocol can be done with or without student involvement.

B. Carbon Cycle Activity and Protocol Flow Charts

Use these clickable flowcharts to decide the best way to use the Carbon Cycle materials in your classroom.

Biosphere, Carbon Cycle Protocol Instructions
Students learn how to evaluate the accuracy of a classification they perform in this tutorial.
Biosphere, Land Cover Classification Learning Activities
Biosphere Data Sheets
Measure the aerosol optical thickness of the atmosphere (how much of the sun’s light is scattered or absorbed by particles suspended in the air). Students point a GLOBE sun photometer at the sun and record the largest voltage reading they obtain on a digital voltmeter connected to the photometer. Students observe sky conditions near the sun, perform the Cloud, Barometric Pressure and Relative Humidity Protocols, and measure current air temperature.
