TechCard and selected mechanical components are available in separate resource packs. These are especially useful for teachers taking a "design and make" approach to technology or where specific topics are being taught. For example, a teacher wanting pupils to investigate pulleys can purchase a pack of TechCard and a pack of pulleys so pupils can devise models to demonstrate their use. A sheet of notes is included with each pack.
