In this scenario-based, problem-based learning (PBL) activity, students investigate cloud formation, cloud classification, and the role of clouds in heating and cooling the Earth; how to interpret TRMM (Tropical Rainfall Measuring Mission) images... (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 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)

This activity will show students how to determine rate of evaporation and the atmospheric factors that can affect this rate. Laboratory equipment needed for this investigation includes: a digital balance or triple beam balance, metric ruler in... (View More)

This is an activity involving scientific inquiry. Using a constructed Mystery Light Box, learners will observe what is in the box without removing the object from the box, shining a light into the box, or reaching hands into the box, and they will... (View More)

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... (View More)

This is a series of three activities about light and spectra. First, learners will construct their own spectroscope, observe common light sources, record the observed spectra, and compare their findings. Next, learners will use their spectroscopes... (View More)

This activity is about the discovery of water ice on Mars. Learners will record and graph temperature data and use a model of an ice-rich and ice-free surface on Mars to examine how ice content in the martian soil would impact the temperature of a... (View More)

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... (View More)

This is an activity about understanding how the Earth’s axial tilt changes the angle at which sunlight hits the Earth, contributing to the variations in temperature throughout the seasons. Learners will create a sun angle analyzer in order to see... (View More)
