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. They use the right-hand rule to explore the rotations of objects. A worksheet is provided. This activity is part of a multi-activity series towards improving spatial visualization skills. At activity end, students re-take the 12-question quiz they took in the associated lesson (before conducting four associated activities) to measure how their spatial visualizations skills improved.

Student groups use a "real" 3D coordinate system to plot points in space. Made from balsa wood or wooden dowels, the system has three axes at right angles and a plane (the XY plane) that can slide up and down the Z axis. Students are given several coordinates and asked to find these points in space. Then they find the coordinates of the eight corners of a box/cube with given dimensions.

Students learn how to create two-dimensional representations of three-dimensional objects by utilizing orthographic projection techniques. They build shapes using cube blocks and then draw orthographic and isometric views of those shapes—which are the side views, such as top, front, right—with no depth indicated. Then working in pairs, one blindfolded partner describes a shape by feel alone as the other partner draws what is described. A worksheet is provided. This activity is part of a multi-activity series towards improving spatial visualization skills.

Draw your 2D molecule and then visualise it as 3D using MolView. This platform is FREE and you can use it straight from your internet browser. The 13-minute video tutorial shows how you can draw your chemical compound(s) in MolView and then convert it to 3D. This platform would be useful for students and researchers since it can be learned quickly and lets you visualise molecular structures easily. Plus,  you can do quick search for drug information from PubChem in MolView. This resource and platform would also benefit instructors who are conducting online teaching and learning activities, and for students doing self-study #molview #3D #visualisation 

This lesson unit is intended to help you assess how well students are able to: recognize and use common 2D representations of 3D objects and identify and use the appropriate formula for finding the circumference of a circle.

Students will learn about basic shapes in Monet's painting "Wheatstacks, Snow Effect, Morning". They then learn about light and shadows through reading and experimenting with three-dimensional models and flashlights. Students will also learn about time of day and the seasons.
