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 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)

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)

In this laboratory activity, learners explore the difference between heat and temperature, and explore the rate of heat transfer from one substance to another as it depends on the density of the substances being investigated. The activity can be... (View More)

In this introductory classroom activity, students exercise their scientific skills of observation and deduction as they use their senses and simple laboratory assays, such as pH indicator paper, to identify mystery pollutants in water samples.... (View More)

In this lab-based activity, students learn how to use scientific instruments used to take hydrological data. Students will rotate among measurement stations for each of the hydrology protocols that will be done by the class. They will practice using... (View More)

This is an activity about the magnetic deflection. Learners will observe and measure the deflection that an iron mass causes in a soda bottle magnetometer and plot the data. The data should show the inverse-square cube law of change in the magnetic... (View More)

Audience: High school

This is an activity about the effect of solar storm events on Earth's magnetic field. Learners will construct a soda bottle magnetometer, take it home, collect data over the course of three days, and analyze the results from several of these data... (View More)

Audience: Middle school

This is an activity about Earth's magnetosphere. Learners will use a magnet, simulating Earth's protective magnetosphere, and observe what occurs when iron filings, simulating the solar wind, blow past and encounter the magnet's field. This is the... (View More)

Audience: Elementary school

In this hands-on experiment, students will investigate the basic principle of photosynthesis and learn how light intensity diminishes as a function of distance from the light source. Questions help learners connect these two ideas to determine if... (View More)
