This module focuses on ultraviolet radiation on Earth and in space and how it affects life. Learners will construct their own "martian" using craft materials and UV beads. They will explore how UV radiation from the Sun can affect living things,... (View More)

Audience: Informal education

In this activity, student teams will create a controlled experiment by building ecosystems in two 2-liter bottles. Teams determine the control conditions of both bottles, identify a test variable, and run the experiment for several weeks to... (View More)

In this laboratory activity, students investigate chromophoric dissolved organic matter (CDOM) through gradual dilution of black, green and chamomile tea. Through this activity, students discover how CDOM can dominate the absorption of sunlight, how... (View More)

In this laboratory activity, students experiment with becomes CO² concentrations in water as a prelude to investigating the marine carbon cycle. The activity includes a worksheet and assessment questions. Tap water, ocean water (real or simulated),... (View More)

This activity guides students through sampling, identification and counting of macroinvertebrates sampled in a GLOBE hydrology study site, and understand how the taxa composition found in the sample can be an indicator of water quality and ecosystem... (View More)

This activity is about the discovery of water ice on Mars. Learners will record and graph temperature data and use a model of an ice-rich and ice-free surface on Mars to examine how ice content in the martian soil would impact the temperature of a... (View More)
