Part 1: Links and Guiding Controls
The purpose of this part of the lesson is to orient students to the key vocabulary used when discussing links by making the connection between everyday items and the new vocabulary (direct or indirect; removable or non-removable; rigid or elastic; complete or partial).
Note: Teachers in Quebec may use the Eureka textbook (Student book A pp. 396-399, Student book B pp. 69,384, 392-3955). Teachers could find examples of links and guiding controls from the internet (see below) to help students complete the following table.
Ask students search in their pencil cases, look at their clothes, or the teacher can provide a variety of household items OR lab equipment. Students should find a minimum of 5 different links. Next they summarize the characteristics of their links in the following table. There are also examples/pictures of links in the textbook, or on the internet (see video link as well as other internet links). Students also evaluate the object to determine if there is a guiding control. Students can work in groups, and use their textbooks or other resources to articulate their ideas:

	Object	Direct or Indirect	Removable or Non-removable	Rigid or Elastic	Complete or Partial	Presence Of Guiding Control
