This demonstration shows that similar-appearing lights can be distinctly different, suggesting that the light emitted is generated in different ways. It requires some advance preparation/setup by the teacher and three recommended sources of orange... (View More)

This is a design challenge about heat transfer and insulation. Learners will apply the scientific method to design and build a container that will keep items cool when placed in boiling water. They will practice collaboration in team-building and in... (View More)

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 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 activity requires construction of a simple salinity tester. Students will create their own calibration scale during this experiment, and look at the change in salinity that would arise if freshwater was suddenly dumped into the ocean. Materials... (View More)

This is an activity about polarized light. Learners will use a polarizing filter to build and calibrate a simple polarimeter, use the constructed polarimeter to find sources of polarized light, and measure the angle of polarization of polarized... (View More)

In this activity, learners will explore the properties of color filters and filter bandpass by observing light sources using diffraction grating and color filters and create a graph of percent transmission versus wavelength to characterize the... (View More)

This is an activity about the movement of sunspots. Learners will project an image of the Sun using a telescope, binoculars, or a pinhole projector, observe and record sunspots over the course of several days, and calculate the speed of the observed... (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 activity is about the remote operation of planetary rovers. Using remote control cars and other materials, learners will simulate the experience of trying to operate a planetary rover and working as a team to address challenges and meet a... (View More)
