This is a hands-on lab activity about the composition of salt. Learners will explain the general relationship between an element's Periodic Table Group Number and its tendency to gain or lose electron(s), and explain the difference between molecular... (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 is an activity about the properties and characteristics of Earth’s magnetic field as shown through magnetometer data and its 3D vector nature. This resource builds understanding of conceptual tools such as the addition of vectors and... (View More)

This is an activity about changes in the Earth's magnetic field during magnetic storms. Learners will construct a soda bottle magnetometer, collect data, and analyze the results to detect magnetic storm events. The operation of the student-created... (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)

This activity focuses on the question, What do active galaxies look like when viewed from different distances? Students work in small groups to learn about the small angle formula, construct a template, and use it to correctly measure the angular... (View More)
