See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law. The sizes of the symbols in the equation change to match the circuit diagram.

In this extension to the Ohm's Law I activity, students observe just how much time it takes to use up the "juice" in a battery, and if it is better to use batteries in series or parallel. This extension is suitable as a teacher demonstration and may be started before students begin work on the Ohm's Law I activity.

See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law. The sizes of the symbols in the equation change to match the circuit diagram.

Students work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. They learn about Ohm's law, power, parallel and series circuits, and ways to measure voltage and current.

This lesson will allow students to explore an important role of environmental engineers: cleaning the environment. Students will learn details about the Exxon Valdez oil spill, which was one of the most publicized and studied environmental tragedies in history. In the accompanying activity, they will try many "engineered" strategies to clean up their own manufactured oil spill and learn the difficulties of dealing with oil released into our waters.

This hands-on experiment will provide students with an understanding of the issues that surround environmental cleanup. Students will create their own oil spill, try different methods for cleaning it up, and then discuss the merits of each method in terms of effectiveness (cleanliness) and cost. They will be asked to put themselves in the place of both an environmental engineer and an oil company owner who are responsible for the clean-up.

Students learn about oil spills and their environmental and economic effects. They experience the steps of the engineering design process as they brainstorm potential methods for oil spill clean-up, and then design, build, and re-design oil booms to prevent the spread of oil spills. During a reflective session after cleaning up their oil booms, students come up with ideas on how to reduce oil consumption to prevent future oil spills.

The lesson begins by introducing Olympics as the unit theme. The purpose of this lesson is to introduce students to the techniques of engineering problem solving. Specific techniques covered in the lesson include brainstorming and the engineering design process. The importance of thinking out of the box is also stressed to show that while some tasks seem impossible, they can be done. This introduction includes a discussion of the engineering required to build grand, often complex, Olympic event centers.

Students use three tracks marked on the floor, one in yards, one in feet and one in inches. As they start and stop a robot specific distances on a "runway," they can easily determine the equivalent measurements in other units by looking at the nearby tracks. With this visual and physical representation of the magnitude of the units of feet, yard and inches, students gain an understanding of what is meant by "unit conversion." They also gain a familiarity with different common units of measurement. They use multiplication and division to verify their physical estimated unit conversions. Students also learn about how common and helpful it is to convert from one unit to another in everyday situations and for engineering purposes. This activity helps students make the abstract concept of unit conversion real so they develop mental models of the magnitude of units instead of applying memorized conversion factors by rote.

This game game supports students in counting forward and can be adjusted to support backward counting.

Students learn that charge movement through a circuit depends on the resistance and arrangement of the circuit components. In a hands-on activity, students build and investigate the characteristics of series circuits. In another activity, students design and build a flashlight.

This short video and interactive assessment activity is designed to teach fourth graders about one-step subtraction conversions with compound units (metric units) - word problems.

This task acts as a bridge between understanding place value and using strategies based on place value for addition and subtraction.

In this activity, students learn about ocean currents and the difference between salt and fresh water. They use colored ice cubes to see how cold and warm water mix and how this mixing causes currents. Also, students learn how surface currents occur due to wind streams. Lastly, they learn how fresh water floats on top of salt water, the difference between water in the ocean and fresh water throughout the planet, and how engineers are involved in the design of ocean water systems for human use.

Texting and chatting online can sometimes feel just like talking to someone in person, but it's actually pretty different. It's all because of something called the "online disinhibition effect," which makes us more likely to share or communicate differently from how we would in person. Help your students learn to consider this concept before they post, and stop digital drama and cyberbullying before they start.

While essays and research papers are likely the most common types of writing assignments you’ll receive in college, more and more, students are being expected to write in digital environments. In the 21st century, you’re likely to be asked to create a PowerPoint or Prezi to present the main points of your research paper, or you may be asked to create an electronic portfolio to share all of your work for a semester. Students in online classes will write discussion board posts every week, and some professors are even replacing some of your traditional essay assignments with assignments like photo essays or video essays.

The OER Toolkit aims to improve equitable access to open learning resources and services to college students by providing a province-wide academic support platform for faculty to use while designing courses and assignments. The Toolkit is a one-stop guide to open educational resources, providing faculty and library staff with tools and information to understand, engage with, create, and sustain OER in their work and practice.

The Toolkit is designed to be used by anyone involved with OER at an academic institution, whether you are part of a team that is collaborating to create OER, a library staff member who is supporting OER development and use, an advocate for OER at your institution, or an instructor seeking to incorporate OER and open pedagogy in the classroom. The primary purpose of this Toolkit is to support faculty and library staff at Ontario colleges; however, it is openly available for use beyond the Ontario college community.

Looking at models and maps, students explore different pathways and consequences of pollutant transport via the weather and water cycles. In an associated literacy activity, students develop skills of observation, recording and reporting as they follow the weather forecast and produce their own weather report for the class.

Offered as an introduction to the field of data structures and algorithms, Open Data Structures covers the implementation and analysis of data structures for sequences (lists), queues, priority queues, unordered dictionaries, ordered dictionaries, and graphs. Focusing on a mathematically rigorous approach that is fast, practical, and efficient, Morin clearly and briskly presents instruction along with source code.

Analyzed and implemented in Java, the data structures presented in the book include stacks, queues, deques, and lists implemented as arrays and linked-lists; space-efficient implementations of lists; skip lists; hash tables and hash codes; binary search trees including treaps, scapegoat trees, and red-black trees; integer searching structures including binary tries, x-fast tries, and y-fast tries; heaps, including implicit binary heaps and randomized meldable heaps; graphs, including adjacency matrix and adjacency list representations; and B-trees.

A modern treatment of an essential computer science topic, Open Data Structures is a measured balance between classical topics and state-of-the art structures that will serve the needs of all undergraduate students or self-directed learners.
