This video is the second lesson in the How Cold Is Cold? BLOSSOMS series and examines the properties of materials under low temperature conditions. The video consists of a series of fascinating demonstrations with liquid nitrogen, which boils at 77K (-196 C -321 F). These demonstrations include the following: What goes up, may not come down; Is that supposed to be cold? - thermal insulation; Some properties of liquid nitrogen; Making ice cream - the slow way and the fast way; Try not to explode: expansion of liquid nitrogen and the ideal gas law; Making the air cold: phase changes and the affect on volume; No frozen fingers: the changes in mechanical properties; Resistivity at 77K; The magic magnet: the Meissner Effect; Cautions in using liquid nitrogen

SSAC Physical Volcanology module. Students build a spreadsheet to examine how magma viscosity varies with temperature, fraction of crystals, and water content using the non-Arrhenian VFT model.

This Flash animation describes how hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.

This illustrated essay from A Science Odyssey Web site explains the science behind radio waves, including the role of electrons and electromagnetic fields.

In this video segment adapted from Shedding Light on Science, observe demonstrations of the fundamental idea that light travels in straight lines.

Use the Sound Grapher to create visualizations of sound and learn about the frequency, wavelength, amplitude and velocity of sound waves.

Spreadsheets Across the Curriculum module. Students build a spreadshet to calculate grams solute to add to liters solvent to produce solution of desired concentration (mol/L).

In this fast-paced NASA Brain BitesŒ_íěÖ video, an astronaut demonstrates the impact of microgravity on the use of tools in space.

SSAC Physical Volcanology module. Students build a spreadsheet to calculate velocity of rising magma in steady-state Plinian eruptions using conservation of mass and momentum.

In this activity, students investigate how the atmosphere changes with altitude. They will obtain atmospheric data for locations of their choosing using online resources, graph it, and examine it to answer questions about changes in temperature, pressure, humidity, and dewpoint with altitude.

This short video reviews how nations and individuals can work together to reduce the emission of CO2. It discusses strategies to reduce greenhouse gas emissions (energy conservation, renewable energies, change in energy use) and the role that government can play in this process.

How to be a successful organic chemist is meant as an introductory text for undergraduates taking organic chemistry teaching labs. The text is a clear and practical introduction to safety, chemical handling, organic chemistry techniques, and lab reports.

This video segment adapted from the Space Telescope Science Institute shows what the Hubble telescope found when it stared at a single, nearly empty spot in the sky for 10 days in 1995. The unexpected result was a picture of a multitude of galaxies stretching into the distance.

In this activity, students investigate data from Hurricane Ivan, the September 2004 storm that devastated the Caribbean Islands and the Alabama Gulf Coast before looping across Florida and back into the Gulf of Mexico, where it regenerated into a new storm system. They will analyze data on the storm's location, windspeed, and barometric pressure, develop study questions, and map the hurricane's position at selected intervals.

During this activity students build a plastic pipette rocket. The first concept will to learn how igniting varying mixtures of hydrogen and oxygen will affect how far the rocket will fly. Second students will observe and manipulate variables to better understand the fundamental chemistry concepts: principles of combustion reactions, kinetics, stoichiometry, gas mixtures, rocketry, and different types of chemical reactions. Finally, students will assess their own understanding of these chemistry concepts by investigating how NASA scientists launch real rockets into space. One follow-up activity would be to investigate and collect data on a launching a heavier object at the school football field.

This lab gives students the opportunity to find the optimum mixture of hydrogen and oxygen as they react on a micro-scale.

This module discusses the hydrologic cycle and its impacts on the planet Earth. Additionally, the module addresses connections between the hydrologic cycle, climate and the impacts humans have had on the cycle.

The EERC at the University of Bristol has developed an Earthquake Engineering Competition that challenges secondary school students to design and make small scale models of buildings that can withstand strong earthquakes. Provided on the website are tips for model design and construction, load testing advice, and a gallery of models organized by various characteristics.

CH104

DESCRIPTION
Introduces basic principles of general chemistry, including atomic theory, chemical formulas and equations, bonding, stoichiometry, acid/base chemistry, and solutions. Supporting laboratory work included. Not designed for science majors.

LEARNING OUTCOMES
1. Interpret the periodic table to describe elements of atomic structure for the elements and to make predictions about properties based on the position of elements on the table.
2. Apply atomic theory in describing atomic structure, making predictions about bonding and compound formation, and interpreting chemical reactions.
3. Construct and interpret Lewis structures as models for ionic and covalent compounds.
4. Describe ionic and covalent bonding and distinguish between the two, including descriptions of substances of each type at the observable scale.
5. Solve problems using dimensional analysis involving chemical substances and reactions, drawing on understanding of the mole concept, formula masses and reaction stoichiometry.
6. Read, write, and interpret balanced chemical equations, using proper equation syntax and standard symbolism to link such descriptions to phenomena that occur at the observable scale.
7. Interpret and carry out a set of written experimental instructions and then to convey the experimental results in a laboratory report.
8. Apply kinetic-molecular theory to describe solids, liquids, and gases.
9. Recognize acids and describe acidity according to the Bronsted-Lowry definition.
10. Use scientific (inductive) reasoning to draw appropriate conclusions from data sets or theoretical models. Characterize arguments as scientific, or not scientific.
11. Make measurements and operate with numbers properly to convey appropriate levels of certainty when drawing conclusions from experimental data. Identify patterns in data by graphical means.
