The convection of heat in air happens naturally because warmer air is less dense and rises, causing air circulation in many situations. But not always! Air can stratify, with warmer air up high and cooler air down low. With this model you can explore how convection works if the heat source is near the ceiling of a room. You can also compare it to conduction in the same setting.

Air circulates quickly and easily if there are temperature differences to drive its motion. This may be desirable in a room, but in insulated walls and ceilings air circulation is a problem, since it transfers heat. Explore the effect of multiple barriers on the amount of convection and apply this to how insulation should be designed.

Most buildings have leaky places where air can enter or escape -- around windows, ceiling openings like pipes, wires or chimneys, and construction joints such as where the wall meets the floor or the floor rests on the foundation. The size and location of these leaks strongly affects the heating and cooling load. Use this model to experiment with wall and roof leaks in a house with a heater where the air can circulate freely.

A compilation of video scenarios of people interacting with each other in Portuguese. Conversations include dialogs, questions, turn taking exchanges, clarifications, false starts, hugs, laughter, asides. The scenarios are enhanced by transcriptions, translations, content analysis, and notes and discussion blogs.

Simple prompts on each slide guide a discussion about school culture, from clothing and food to homework, subject matter and sports. Sets the stage for cultural comparisons, study of "se impersonal," review and extension of beginner vocabulary. Prompts could subsequently be used as a writing or speaking assessment.

Conversation slides that help students review and use frequent vocabulary. What do you do before/after....?

Students will be able to prepare answers to the conversation starters and then talk to their partners

Explore how potential energy created by particles of varying charge is converted to thermal energy.

Using proportions to convert between and among measurement systems.Mathematics Instructional Plans (MIPs) help teachers align instruction with the 2016 Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom.

Energy is continuously transferred from one place to another and transformed among various forms. In this lesson students will learn and demonstrate how energy is transferred from one form to another through various sequences. Additionally, they will explore binary code and how it can be converted from one form into another and transferred from one object to another.

Students will program a Sphero robot to travel around the exterior of a convex polygon. Students will then use the information in their code to determine the sum of the interior angles in a convex polygon.

Learn how to work with images in PowerPoint. This EdTech Short shows you how to remove backgrounds from images and how to create image animations.  Addresses ISTE Standard for Educators: 2.5 Designer 

Jamboard of Coordinate Plane.  Drag and drop to label the coordinate plane.  Go to second slide and drag and drop the ordered pairs with the quadrants or axis.

This is a set of three, one-page problems about how astronomers use coordinate systems. Learners will plot a constellation on a coordinate plane and/or plot the route of Mars Science Lab (MSL aka Curiosity) on the surface of Mars. Options are presented so that students may learn about the MSL mission through a NASA press release or about the coordinate plane by viewing a NASA eClips video [7 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.

This activty will help students practice accurately naming coordinates and locating points on the coordinate plane.

In this activity, students will discover how to determine the distance between two points on the same horizontal or vertical line.
