This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More) textbook chapter, What Heats the Earth's Interior?, part of the unit, Energy Flow, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

Sea floor spreading is demonstrated using a model consisting of two classroom desks and an 8-foot strip of paper. Changes in polarity are indicated using a felt marker. The investigation supports material presented in chapter 3, "What Heats the...

In this demonstration, a plastic soft drink bottle is used to demonstrate properties of gases and liquids with respect to temperature and pressure. Calculations using the formula for the Ideal Gas Law are included. The resource is from PUMAS -... (View More) Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This is a lesson about the formation of plasma bubbles in Earth's ionosphere. Plasma bubbles cause stars to twinkle and radio signals from satellites to distort. Learners will build a model ionosphere in order to demonstrate and understand this... (View More) process. This activity requires special materials including a laser pointer and silicon-based glue.

In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the... (View More) motions of the Moon about the Earth and the Earth about the Sun, and then test their understanding using an experimental apparatus made from a cardboard or plywood disk and rope. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

In this demonstration, an apple is used to help students visualize the relative amounts of land and water resources on the planet, and highlights the vulnerability of these resources we share. The apple is sectioned proportionately according to... (View More) different categories of resources and land use. Questions are provided to guide a discussion. This activity is supported by a textbook chapter, One Global Ocean, part of the unit, Losing Biodiversity, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

This is an activity about collecting, describing and classifying terrestrial and lunar rocks. Learners will collect and describe rocks of varying texture, color and shapes. Descriptors will include color, presence or absence of grains and grain... (View More) size, textures, banding and other patterns. From the descriptions, learners will classify their collected rocks and extend their knowledge to classify lunar rocks. This activity is in Unit 1 of the Exploring the Moon teacher's guide and is designed for use especially, but not exclusively, with the Lunar Sample Disk program. (View Less)

Learners simulate the process of geological differentiation. The activity ends with an extension question that asks about the makeup of the highlands of the Moon. This activity is in Unit 2 of the Exploring the Moon teacher's guide and is designed... (View More) for use especially, but not exclusively, with the Lunar Sample Disk program. (View Less)
