In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

This textbook chapter outlines the historical development of the Theory of Natural Selection, presenting classic evidence including Darwin's study of finch beak variation in the Galapagos Islands and Kettlewell’s investigation of the pepper moth... (View More)

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)

Working in pairs or small groups, students use construction paper to simulate cloud cover. They estimate the percentage of cloud cover represented by torn pieces of paper on a contrasting background and assign a cloud cover classification to the... (View More)

In this activity, students plot data from GLOBE schools on a map with latitude and longitude lines and draw contours based on the values plotted. The resource includes a student worksheet and data table. Several suggestions for extensions of this... (View More)

Students become aware of the changes in visibility and sky color due to particles suspended in the air, called aerosols. They observe, document and classify changes in visibility and sky color over several days and understand the relationship... (View More)

In this activity, students observe and sketch clouds, describing their forms. They will initially generate descriptions of a personal nature and then move toward building a more scientific vocabulary. They correlate their descriptions with the... (View More)

In this investigation students explore how resolution affects information content on remotely sensed images, relate remote sensor resolution (pixel size) to information content, and gain an understanding of the information content of different kinds... (View More)

Students examine a series of remotely-sensed images of the US, scaling from the continent to San Francisco, and distinguish the concepts of scale and resolution. At greater resolution, students are able to identify different land classes on the map,... (View More)
