Students will study how temp and concentration affect reaction rates and then design a procedure to get the reaction to occur in a specified amount of time.

The purpose of this resource is to have students observe their lilac plants and identify the five phenophases (first leaf, full or 95% leafed, first bloom, full bloom and end of bloom) for each lilac plant. During the growing season, students will observe their lilac plants and identify the five phenophases (first leaf, full or 95% leafed, first bloom, full bloom and end of bloom) for each lilac plant.

Coalbed methane (CH4) is a natural gas and valuable energy resource that occurs in coal beds. This site, hosted by an energy development corporation, explains the geology and stratigraphy of Wyoming in the context of the formation of coalbed methane and its occurrence in Wyoming. Maps, cross sections, stratigraphic columns and fence diagrams are provided to explain Cretaceous and Tertiary coalbed methane-plays in Wyoming.

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.

Climographs, graphic plots of monthly temperature and precipitation, allow students to see how differences in insolation at various locations affect rates of heating and cooling. In this activity, students use climographs to plot locations using latitude and longitude, calculate annual temperature ranges, and relate unequal rates of heating and cooling to climate variations. They will also construct climographs for two locations in New York, analyze them, and answer questions about their observations.

The fundamental concepts of inorganic chemistry including the physical and chemical properties of matter, atomic structure, chemical bonding, stoichiometry, the gas laws, solutions, acids and bases, redox reactions, and chemical equilibria. All course content created by Patricia Richard. Content added to OER Commons by Joanna Gray.

Short Description:
Ten general chemistry semester one lab exercises testing the topics of measurement, light and energy, stoichiometry, solubility, metals activity, calorimetry, and gas behavior.

Long Description:
This lab manual was designed as an inclusive lab experience covering scope and sequence for the first semester general chemistry course at the College of Western Idaho. It includes hands on activities and prompts writing and data processing associated with varied general chemistry topics following an atom’s first approach and including measurement, light and energy, stoichiometry, solubility and activity, calorimetry, and gas behavior. The manual also includes a calculation and statistical analysis appendix, sample reports, and a guide to writing reports. Each lab in the sequence is organized with pre-lab questions, a safety overview, an historical and chemical background and lab instructions as well as lab reporting instructions.

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.

Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

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.

In this video segment from ZOOM, Hillary, from Randolph, MA, takes us on a tour of the columns in her neighborhood.

This activity is a lab designed for students to combust magnesium and use results to explain oxidation/reduction reactions.

This article lists common misconceptions about states and changes of matter and the water cycle. It provides formative assessment probes and information about teaching for conceptual change.

In this activity, students collect data and analyze the cost of using energy in their homes and investigate one method of reducing energy use. This activity provides educators and students with the means to connect 'energy use consequences' and 'climate change causes.' Through examining home energy use and calculating both pollution caused by the generation of electricity and potential savings, students can internalize these issues and share information with their families.

The purpose of the resource is to produce a land cover type map from the digital file of a Landsat satellite image using MultiSpec software.

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation!

"Concept Development Studies in Chemistry" is an on-line textbook for an Introductory General Chemistry course. Each module develops a central concept in Chemistry from experimental observations and inductive reasoning. This approach complements an interactive or active learning teaching approach.
