In this activity students use log tapes and base-two slide rules as references to graph exponential functions and log functions in base-10 and base-2. Students discover that exponential and log functions are inverse, reflecting across the y = x axis... (View More)

In this online, interactive module, students learn how enhanced Earth remote-sensing capabilities are used by dozens of satellites that are continuously collecting data from multiple vantage points. This allows scientists from different countries to... (View More)

In this problem-based learning activity, students learn about weather forecasting and the role of the TRMM (Tropical Rainfall Measuring Mission) satellite in data collection. Assuming the role of climatologists, students assist a reporter in... (View More)

In this activity students construct multiplying slide rules scaled in Base-10 exponents and use them to calculate products and quotients. They will come to appreciate that super numbers (exponents, orders of magnitude and logarithms) play by... (View More)

This interactive, online activity allows students to explore Hubble's deepest surveys of the far universe and distant galaxy surveys made by Hubble and other observatories. This activity includes science content reading material for the online... (View More)

Audience: Middle school

In this fieldwork activity, students learn that when setting up a research design a system's boundaries are based on the question(s) a scientist wants to answer. Students ground truth, or validate, a pixel within a homogeneous area of a satellite... (View More)

In this problem-based learning (PBL) activity, students take on the role of a student research scientist and explore the role of solar energy in determining climate. Students conduct experiments to observe how a change in water phase affects surface... (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 activity, students build a model of an active galaxy. From this, they will learn about the geometry of the components of an active galaxy and develop an understanding that different viewing angles can lead to dramatically different... (View More)
