In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.

A car propelled by the reaction between lemon juice and baking soda has more in common with rockets and jet aircraft than one might think. In this video segment adapted from ZOOM, two cast members demonstrate the power of rocket-propelled vehicles and how to exploit the force produced by the carbon dioxide gas. Grades 3-8.

This is a series of activities demonstrating that air has mass, takes up space, and can exert a force on objects enough to lift them.

This collection of still images presents different ways to visualize air, from billowing sails to windblown hair to tornadoes.

Fundamentals of nuclear physics for engineering students. Basic properties of the nucleus and nuclear radiations. Elementary quantum mechanical calculations of bound-state energies and barrier transmission probability. Binding energy and nuclear stability.

In this hands-on OLogy activity, kids learn about matter by building their own models of carbon out of pipe cleaners, wire, and clay. The activity begins with a kid-friendly introduction to matter, elements, and atoms. The illustrated, step-by-step directions show kids how to use the information about carbon on the Periodic Table to create a mobile that shows the element's basic structure. A PDF version of the Periodic Table, along with a kid-friendly overview of how to read it, is also included.

Students are introduced to chemical engineering and learn about its many different applications. They are provided with a basic introduction to matter and its different properties and states. An associated hands-on activity gives students a chance to test their knowledge of the states of matter and how to make observations using their five senses: touch, smell, sound, sight and taste.

Tnis 19-minute video lesson provides an Introduction to the states (or phases) of matter. [Chemistry playlist: Lesson 25 of 106].

This 9-minute video lesson provides more information on Plasma and Hydrogen bonds. [Chemistry playlist: Lesson 26 of 106].

Students are introduced to the concept of different kinds of matter. Students create models of different substances to learn to identify the differences between elements, compounds, and mixtures. This lesson is developed so that teachers can use it with English as a Second Language students.

This unit explores issues related to size and scale, specifically the effect of the size of nanopowders on the interactions of energy and matter (e.g., the absorption of light, addressing the electromagnetic spectrum and associated wavelengths). For example, old sunscreens use "large" zinc oxide particles, which block ultraviolet light but scatter visible light, giving the cream a white color. If nanopowders of zinc oxide are used instead, the cream is transparent, because the diameter of each nanoparticle is smaller than the wavelength of visible light. Upon completing this unit, students will understand: How the energies of different wavelengths of light interact differently with different kinds of matter; Why particle size can affect the optical properties of a material; That there may be health issues for nanosized particles that are undetermined at this time; That it is possible to engineer useful materials with an incomplete understanding of their properties; There are often multiple valid theoretical explanations for experimental data; to find out which one works best, additional experiments are required; How to apply their scientific knowledge to be an informed consumer of chemical products. Length: 5 lessons, up to 11 50-minute classroom periods if all lessons are used. Not all lessons are required. Use the lessons most appropriate for your students.

This module focuses on the launch and propulsion of the Genesis spacecraft. Students will become familiar with how rockets are launched, learn how and why specific rockets are chosen for varying payloads, learn about the history of rocketry, and work with variables that might affect the performance of a launch vehicle. They will work in teams to test a single variable involved in launching a rocket and learn the variables involved with constructing and launching a water rocket. Each activity includes a teacher's guide and students handouts. Video and audio clips are provided.

This module engages students in the use of a clean room and in the planning of assembly of solar collector wafers for the Genesis space mission. They will work in production design teams to explore how the Genesis spacecraft will collect bulk solar wind with the collector arrays and learn to work as a team in a restrictive environment. The module includes several activities with accompanying video clips. Downloadable, printable teachers' guides and students pages are provided for each one.

The students will be able to identify concepts that guide scientific investigations, recognize and analyze alternative explanations and models by the end of this activity.

Students use a Although atoms contain both negatively and positively charged particles, they do so in equal amounts and carry no net charge. This balance can be temporarily disrupted by rubbing one material against another. One device, known as a Van de Graaff generator, uses a fast moving rubber belt to charge a metallic dome to nearly 200,000 Volts. This activity uses a Van de Graaff generator to study the behavior of electrical charges.

This is a comprehensive science textbook for Grade 10. You can download or read it on-line on your mobile phone, computer or iPad.

In this video from Evolution, an exploration of multi-drug resistant tuberculosis in the Russian prison system highlights one reason it is important to understand evolution.

This lesson plan explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. Students think about how atoms and molecules can influence new technologies developed by engineers.

This course focuses on the fundamentals of structure, energetics, and bonding that underpin materials science. It is the introductory lecture class for sophomore students in Materials Science and Engineering, taken with 3.014 and 3.016 to create a unified introduction to the subject. Topics include: an introduction to thermodynamic functions and laws governing equilibrium properties, relating macroscopic behavior to atomistic and molecular models of materials; the role of electronic bonding in determining the energy, structure, and stability of materials; quantum mechanical descriptions of interacting electrons and atoms; materials phenomena, such as heat capacities, phase transformations, and multiphase equilibria to chemical reactions and magnetism; symmetry properties of molecules and solids; structure of complex, disordered, and amorphous materials; tensors and constraints on physical properties imposed by symmetry; and determination of structure through diffraction. Real-world applications include engineered alloys, electronic and magnetic materials, ionic and network solids, polymers, and biomaterials.
