El Nino and Rainfall

An in-depth lesson, the fourth activity in a series of 36, begins with teaching how the periodic table's arrangement came to its current design. Using this knowledge, pupils then move on to analyze the arrangement of elements to their...

Students investigate the energy used by a light bulb. In this electrical energy activity, students conduct an investigation to explain the relationship between the output of light and the electrical power used by a light bulb.

Students explain what El Nino is, where it is located and how it is created. They describe the weather changes caused by El Nino. They draw the patterns of El Nino on a world map. They predict economic effects El Nino has on the areas it...

When provided with multiple objects, how many ways can the class organize and display them based on predetermined factors? Assist class members with a handy activity—theoretically teaching them concepts to understand periodic table...

Students conduct an experiment.  In this El Nino instructional activity, students learn where El Nino storms come from, what they consist of and what effects they have.  Students also complete an experiment where they create a miniature...

Students use satellite data to explore sea surface temperature. They explore the relationship between the rotation of the Earth, the path of ocean current and air pressure centers. After studying maps of sea surface temperature and ocean...

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of matter....

Students use the Internet to research current and past snowpack levels and river gauging station readings. They determine the relationship between snowpack and river flow. They predict future river flow.

Learners evaluate the relationship between rainfall and runoff of a small island for one year. In this rainfall vs. runoff lesson, students analyze the relationship between the rainfall and the runoff on Barro Colorado Island over a...

Young scholars explore the relationship of resistance, voltage, and current in series and parallel circuits using a computer model of a circuit board. They discover Ohm's Law by constructing series circuits.
