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.

Conceptual Chemistry is a year-long course based on CK-12 OER instructional material and supplemented with limited commercially-available materials. The course is project-based, argument-driven inquiry. Each quarter begins with presentation of an intriguing phenomenon, followed by an essential question about the phenomenon, and a project centered on answering that essential question. Throughout the quarter, students conduct research and investigations to answer portions of the question. Each unit has a student "Task" at the end that serves as an assessment of the unit's concepts. At the end of each quarter, students assemble all of the unit tasks and synthesize a personal final project that answers the essential question in a personal context chosen by the student.

This interactive, scaffolded activity allows students to build an atom within the framework of a newer orbital model. It opens with an explanation of why the Bohr model is incorrect and provides an analogy for understanding orbitals that is simple enough for grades 8-9. As the activity progresses, students build atoms and ions by adding or removing protons, electrons, and neutrons. As changes are made, the model displays the atomic number, net charge, and isotope symbol. Try the "Add an Electron" page to build electrons around a boron nucleus and see how electrons align from lower-to-higher energy.

This interactive activity helps learners visualize the role of electrons in the formation of ionic and covalent chemical bonds. Students explore different types of chemical bonds by first viewing a single hydrogen atom in an electric field model. Next, students use sliders to change the electronegativity between two atoms -- a model to help them understand why some atoms are attracted. Finally, students experiment in making their own models: non-polar covalent, polar covalent, and ionic bonds.

This 90-minute activity features six interactive molecular models to explore the relationships among voltage, current, and resistance. Students start at the atomic level to explore how voltage and resistance affect the flow of electrons. Next, they use a model to investigate how temperature can affect conductivity and resistivity. Finally, they explore how electricity can be converted to other forms of energy. The activity was developed for introductory physics courses, but the first half could be appropriate for physical science and Physics First. The formula for Ohm's Law is introduced, but calculations are not required.
