This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the current, I, for each set resistance value, students plot the three points on a Cartesian plane and note the line that is formed. They also see the direct correlation between the amount of current flowing through the lamp and its brightness.

This lesson introduces students to the concept of air pressure. Students will explore how air pressure creates force on an object. They will study the relationship between air pressure and the velocity of moving air.

We developed this Natural Hazards book to fill the void we found and contribute a Canadian version to the public. We both feel that Open Education Resources (OER) are an excellent way to share the body of knowledge and work of those in the Physical Geography discipline. Each chapter in this book started with a chapter drawn from another OER and then edited to our own material we have used while teaching our classes in Natural Hazards for over 15 years. We will use the feedback from our students in 2021 and 2022 classes to finalize this book too.

The video resource "Capacitors and Kirchhoff: Crash Course Physics #31" is included in the "Media Literacy" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Students are presented with a short lesson on the difference between cohesive forces (the forces that hold water molecules together and create surface tension) and adhesive forces (the forces that causes water to "stick" to solid surfaces. The interaction between cohesive forces and adhesive forces causes the well-known capillary action. Students are also introduced to examples of capillary action found in nature and in our day-to-day lives.

Part II of our in-depth look at carbon dioxide, a moleculeoften associated with global warming.

You've probably seen carbon dioxide as a gas and solid but it is much rarer as a liquid.

We take a look at Carbon - one of the most important elements for our lives on Earth. We look at various forms of elemental carbon, from diamonds to exotic graphene and buckyballs. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

Carl Sagan reviews a mail-order mini ecosystem. The resource, "Carl Sagan - Review of the Ecosphere" included in "Lesson 2 Small World Scaling Sustainability" is a part of "Unit 02 Introduction to Science and Engineering Methods" included in Energy & Sustainability ES - Course 1.

Students observe Pascal's law, Archimedes' principle and the ideal gas law as a Cartesian diver moves within a closed system. The Cartesian diver is neutrally buoyant and begins to sink when an external pressure is applied to the closed system. A basic explanation and proof of this process is provided in this activity, and supplementary ideas for more extensive demonstrations and independent group activities are presented.

Maps capture the power of place. A well-designed map can stoke our imagination, helping us to understand how a place looks or feels. Maps serve two roles. First, maps facilitate visual communication where knowns are presented to map readers. Second, maps permit visual thinking where insights into patterns and trends in spatial data are explored. In GEOG 486, Cartography & Visualization, you will learn and apply cartographic theory creating appropriately designed maps. You will learn how to associate the visual variables to symbolize types of spatial data. This process creates an appropriate visual hierarchy that conveys an informational hierarchy about the underlying message. Thus, techniques in map design will be applied to produce, evaluate, and critique reference and thematic maps.

In this video Paul Andersen explains how the three types of catalyst classes act to speed up reactions. Acid-base catalysts either add or remove a proton from one of the reactants. Surface catalysts provide active sites where reactants can adsorb and create more successful collision.

Paul Andersen explains how catalysts can speed up a reaction without being consumed in the reaction. Catalysts can lower the activation energy of reaction be stabilizing the transition state. They can also create new reaction pathways with new reaction intermediates that lower the overall activation energy.
