This is a hands-on lab activity about the chemical composition and conductivity of water. Working in groups, learners will: conduct an experiment involving the process of electrolysis, prepare an experiment to better understand the process of ion exchange, discuss and research the "softness" and "hardness" of water, and use the periodic table to identify elements and learn their characteristics. Background ... Full description.

In this activity, students perform a version of the experiment of 1801, in which ultraviolet light was first discovered by Johann Wilhelm Ritter. This experiment should be conducted outdoors on a sunny day - variable cloud conditions, such as patchy cumulus clouds or heavy haze will diminish your results. This activity requires advance preparation and special materials (e.g., glass prism, blueprint ... Full description.

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 difference they observe. This is a learning activity associated with the GLOBE soil investigations and is supported by the Soils chapter of the GLOBE Teacher's ... Full description.

In this open inquiry activity introducing concepts of remote sensing, students will discuss and research different invisible phenomena. They will then test and verify the existence of selected invisible phenomena by using measurement or detection devices. Depending on the phenomena being investigated, some of the following supplies are suggested: thermometer, light meter, decibel meter, telescope, ... Full description.

In this activity, students are introduced to the concept of remote sensing. In the course of this experiment, students will investigate heat conduction on two surfaces and understand the application of these techniques to spacecraft investigations of surfaces in the solar system. Materials required for the outdoor demonstration include a cement step, sand, laboratory thermometers, foam rubber, and ... Full description.

This is a series of five activities about geology on the moon. Learners will explore lunar stratigraphy (caused by lava flows), impact craters, the moon's history, spacecraft design in which students build models of the LRO out of edible or non-edible materials, and the future of lunar exploration. This guide includes the activities from the original Field Trip to the Moon guide plus activities relating ... Full description.

This is an activity about photosynthesis. Learners will use the basic principle of photosynthesis and investigate how light intensity diminishes as a function of distance from the light source. Questions help them connect these two ideas to determine if photosynthesis could occur at Saturn. Full description.

Students will explore how energy from the sun is absorbed, reflected and radiated back into space by Earth. By completing three short labs investigating the effects of surface color, type of material, or cloud cover on temperature change, students will begin to consider how various surfaces might affect Earth's overall temperature. Earth's energy budget will then be explored through a video, simulation ... Full description.

Students will be introduced to the causes, locations, and hazards of landslides, as well as the role of satellite observations in predicting and studying them. To begin, students investigate the amount of precipitation sufficient to cause a landslide in two different mediums (soil and sand), then use their findings in follow-up activities. After the lab, students will think about how rain information ... Full description.
