This activity promotes student understanding of some of the movements that take place when warmer water and cooler water interface, and how differences in densities, resulting from variations in temperature, set molecules of liquids and gases in... (View More)

This chapter provides a series of investigations, ranging from teacher-centered to open inquiry, that involve the formation of clouds in a model cyclone, and demonstrating how the availability of heat (indicated by temperature) affects formation and... (View More)

This experimental activity is designed to develop basic understanding of the relationship between the angle of light rays and the area over which the light rays are distributed, and the potential to affect changes in the temperature of materials.... (View More)

This is a lesson about solar system exploration. Learners will understand that combining information gathered by a variety of robots gives us a more comprehensive understanding of our solar system. Learners will explore a planet made up of a... (View More)

This is an activity about modeling and the scientific process. Learners will discuss the models they created in the previous three activities as models of forces that shape the surface of planets, and talk about the similarities and differences... (View More)

This activity explores how ancient Sun observers made use of natural and built structures to mark solar alignments observed at different times of the year, particularly around the solstices and equinoxes. In Part 1, the teacher prepares a horizon... (View More)

This is a lesson about the phenomenon of ice and about scientific inquiry. Learners will ask scientific questions about ice, will delve into the nature of science, embark upon scientific inquiry, and will practice scientific enterprise. Activities... (View More)

In this project, students construct shelters that have varying properties and place them in the same location, or place similar shelters in different locations and compare temperature data taken in each shelter. Students predict what will happen for... (View More)
