This activity is a hands-on activity to help students learn the behavior of gas particles.

This investigation will have students testing how heating and cooling can change the state of matter. They will test a variety of materials determine whether a change takes place through heating/cooling.

This activity examines the characteristics of light. Students demonstrate that light travels straight and does not bend around an object.

This video segment adapted from NASA describes the basic characteristics of our star, the Sun.

A large complete authoritative biography of Coulomb. Five large pictures, over a dozen links to contemporaries, references, a poster, other mathematicians. A fine source.

This activity is a 2 part lab activity where students record properties of various bars of soap, and make models of molecules as they are cooled or heated. Students develop a new experiment changing one variable.

In this video segment adapted from NOVA, scientists are on the hunt for tornadoes. Using Doppler radar, they gather data in the hopes of solving the mystery of how tornadoes form.

Matching game, including matching common ionic charges and ions and the compounds they form and naming of greek prefixes for covalent molecules.

In UCM, the net force called Fc is equal to mv2/r and is directed toward the center. This is demonstrated by an object that is suspended by a string and is moving in a circular path which makes a conical pendulum. In this experiment, you will measure the tension and the length of the string to show that net force Fc = mv2/r.

Students learn about gear ratios and power by operating toy mechanical cranes of differing gear ratios. They attempt to pick up objects with various masses to witness how much power must be applied to the system to oppose the force of gravity. They learn about the concept of gear ratio and practice calculating gear ratios on worksheets, discovering that smaller gear ratios are best for picking objects up quickly, and larger gear ratios make it easier to lift heavy objects.

Students are challenged to design a method for separating steel from aluminum based on magnetic properties as is frequently done in recycling operations. To complicate the challenge, the magnet used to separate the steel must be able to be switched off to allow for the recollection of the steel. Students must ultimately design, test, and present an effective electromagnet.

This article continues an examination of each of the seven essential principles of climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured. Principle 2 covers the complex interactions among the components of the Earth system. The author discusses the scientific concepts underlying the interactions and expands the discussion with diagrams, photos, and online resources.

This interactive resource adapted from the National Park Service describes the different kinds of sediments that make up coastlines, with a focus on the variety in color, size, and sorting.

This interactive resource adapted from the National Park Service describes the many forces that affect shorelines, including tides, weathering, erosion, and deposition.

This professional development article identifies resources that show young learners (K-grade 5) how scientists study Earth's climate and make predictions. The online lessons either allow students to collect and analyze data or learn about tools and technologies that make data collection possible. The lessons are aligned with national content standards for science education. The article appears in the free, online magazine Beyond Weather and the Water Cycle, which examines the recognized essential principles of climate literacy and the climate sciences for elementary teachers and their students.

This video from NASA describes the detailed computer modeling used to predict that colliding neutron stars can produce gamma-ray bursts similar to those associated with black holes.

This is a laboratory exercise designed to allow students to further investigate the light spectrum. This lab is used to have students view the light spectrum first hand as opposed to using lecture alone.

Watch the ZOOM cast find out how many balloons filled with air and then with water are required to support the weight of a cast member.

In this video segment, members of the ZOOM cast experiment by bending and folding sheets of paper into various shapes to see which shape will support the weight of a heavy book.
