These two short online tutorials discuss how the earth rotates and then the earth's revolutions.

In the first URL, the YouTube video explains why earth has spring, summer, autumn and winter seasons. The second URL summarizes the key takeaway points.

This online interactive lesson discusses what reflections are and provides examples of reflections.

This video will look at rotation. Rotation involves turning a shape around a set point.

This online lesson explains what rotations are.

In this lesson you will learn about:

1. Enlargement and reduction of shapes using a scale factor.
2. Reflection of geometric shapes.
3. Translation of geometric shapes.
4. Rotation of geometric shapes.

This online lesson explores the concept of translations.

Students learn about two-axis rotations, and specifically how to rotate objects both physically and mentally about two axes. A two-axis rotation is a rotation of an object about a combination of x, y or z-axes, as opposed to a single-axis rotation, which is about a single x, y or z-axis. Students practice drawing two-axis rotations through an exercise using simple cube blocks to create shapes, and then drawing on triangle-dot paper the shapes from various x-, y- and z-axis rotation perspectives.

An exploration of how the area under a force vs. position graph equals the work done by the force and solves some sample problems.

Outcomes

In this unit you will learn about:

• the concept of work
• understand that work is done by an applied force
• the concept of energy
• identify the different types of energy
• the concept of power
