Links in Technical objects • A link is a fastening unit that attaches two parts of an object together • Different types of links have different characteristics
Removable: the parts can be taken apart without causing damage to the object Non-removable: taking the linked parts apart will damage the object (aka “permanent” link)
Direct: the parts “fit together” without a fastener, like puzzle pieces or Lego blocks • Indirect: the parts need something to hold them together (like glue, a screw, a rivet…)
Complete: no movement between the linked parts • Partial: there can be movement between the linked parts
Rigid: there is no bending between the linked parts • Flexible: one of the linked parts can bend without breaking the object
Types of Links and Guiding Controls • Open your workbook to page 18-19. Complete the tables referring to textbook pages 392-394. Remember to describe the characteristics in your own words.

Energy Transformations • https://www.youtube.com/watch?v=i6e-KrNCe_E • Energy cannot be created or be destroyed. It can only change forms. Energy transformations can occur naturally in our world, or take place in technological systems that we build. • Refer to p. 398-400 in your textbook and complete page 22 in your workbook.
