Nitrogen, one of the most abundant elements in the universe, is essential to life. This interactive activity adapted from the University of Alberta provides an overview of the nitrogen cycle.

The goal of this course is to obtain knowledge of the origins of petroleum and gas. An overview is given on the conditions that are needed for oil and gas to accumulate in reservoirs. Moreover, techniques to find and exploit these reservoirs are highlighted. The focus always is on the task of the petroleum geologist during the different phases of oil and gas exploration and production. After an introduction to the course including typical numbers and historical developments, essential terms and concepts like biomolecules and the carbon cycle are explained.

In this course, you will learn about phase relations as applied to oil and/or gas reservoir processes, enhanced oil recovery, gas pipeline transportation, natural gas processing and liquefaction, and other problems in petroleum production. The primary objective of the course is to apply the thermodynamics of phase equilibrium to the framework for phase behavior modeling of petroleum fluids. The focus of the course will be on equilibrium thermodynamics and its relevance to phase behavior predictions and phase equilibrium data description. We will attempt to apply phase behavior principles to petroleum production processes of practical interest, especially natural gas condensate systems.

Continuation of Physics 1. Topics include: simple harmonic motion, gravitation, fluid mechanics, waves, the kinetic theory of gases, and the first and second laws of thermodynamics. This course is a calculus-based physics course that is required by four-year colleges in science and engineering studies.

Students design and build paper rockets around film canisters, which serve as engines. An antacid tablet and water are put into each canister, reacting to form carbon dioxide gas, and acting as the pop rocket's propellant. With the lid snapped on, the continuous creation of gas causes pressure to build up until the lid pops off, sending the rocket into the air. The pop rockets demonstrate Newton's third law of motion: for every action, there is an equal and opposite reaction.

This course investigates the principles of thermal radiation and their applications to engineering heat and photon transfer problems. Topics include quantum and classical models of radiative properties of materials, electromagnetic wave theory for thermal radiation, radiative transfer in absorbing, emitting, and scattering media, and coherent laser radiation. Applications cover laser-material interactions, imaging, infrared instrumentation, global warming, semiconductor manufacturing, combustion, furnaces, and high temperature processing.

Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters. This simulation is best used with teacher guidance because it presents an analogy of chemical reactions.

By making and testing simple balloon rockets, students acquire a basic understanding of Newton's third law of motion as it applies to rockets. Using balloons, string, straws and tape, they see how rockets are propelled by expelling gases, and test their rockets in horizontal and incline conditions. They also learn about the many types of engineers who design rockets and spacecraft.

David Goldstein of the Natural Resources Defense Council takes a look at the energy use of new appliances like refrigerators compared to the continued energy inefficiency of SUVs. Goldstein is a MacArthur fellow and the author of Saving Energy Growing Jobs. The discussion includes David Greene of the Oak Ridge National Laboratory. (56 minutes)

Students are given a variety of materials and asked to identify each material as a solid, liquid or gas. They use their five senses ‰ŰÓ sight, sound, smell, texture and taste ‰ŰÓ to identify the other characteristics of each item.

Students act as chemical engineers and use LEGO® MINDSTORMS® NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and temperature. Students measure the temperature of water in its solid state (ice) as it is melted and then evaporated.

Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and construction materials when designing sound recording studios, classrooms, libraries, concert halls and theatres.

This guided inquiry learning activity is designed to be used in a large introductory chemistry course. By working in small groups to discuss the presented information and question prompts, students will engage in cycles of exploring and analyzing data, inventing new conceptual understandings, and applying those concepts. Students should be tasked with working together to complete the prompts in each section by a set time limit. After each section is completed, the entire class can share their answers via a personal response system, and the instructor can review and explain the correct responses, using the accompanying slide deck, which translates the problems into multiple-choice prompts.Instructional resources include 1) the learning activity (.docx and .pdf) 2) the learning objects (.docx and .pdf) and 3) the slide deck (.pptx).- Atomic Orbitals- Chemical Fuels- Gas Laws- Intermolecular Forces- pKa Trends- VSEPR

This article assembles free resources from the Water, Ice, and Snow issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

Students learn about the underlying factors that can contribute to Plinian eruptions (which eject large amounts of pumice, gas and volcanic ash, and can result in significant death and destruction in the surrounding environment), versus more gentle, effusive eruptions. Students explore two concepts related to the explosiveness of volcanic eruptions, viscosity and the rate of degassing, by modelling the concepts with the use of simple materials. They experiment with three fluids of varying viscosities, and explore the concept of degassing as it relates to eruptions through experimentation with carbonated beverage cans. Finally, students reflect on how the scientific concepts covered in the activity connect to useful engineering applications, such as community evacuation planning and implementation, and mapping of safe living zones near volcanoes. A PowerPoint® presentation and student worksheet are provided.
