Let’s Take a Spin: One-Axis Rotation
Students learn about one-axis rotations, and specifically how to rotate objects both physically and mentally to understand the concept. They practice drawing one-axis rotations through a group exercise using cube blocks to create shapes and then drawing those shapes from various x-, y- and z-axis rotation perspectives on triangle-dot paper (isometric paper). They learn the right-hand rule to explore rotations of objects. A worksheet is provided. This activity is part of a multi-activity series towards improving spatial visualization skills.

Rotating objects is a technique used in spatial visualization and is part of understanding and effectively utilizing engineering software. Engineers use one-axis rotation drawings to better visualize 3-D objects to make sure their ideas represented on 2-D screens and paper work in the real (3-D) world in which the designs, products and inventions must function and operate. Spatial visualization is an essential skill for engineers to be able to take ideas to the next level; that is—ideas that initially only exist in the mind to something that can be communicated clearly to other engineers, and eventually turned into products, structures and systems.
After this activity, students should be able to:
- Rotate objects about one axis.
- Translate the rotation of one block to a second block.
- Use the right-hand rule to explore rotations of objects.
