1. Summarizing for exam

2. Atomic Theories

4. Distinguishing between Elements, Compounds, and Mixtures
Instructional Approach(s): The teacher should use the images on the slide to illustrate the differences between elements, compounds, and mixtures

5. Distributed Summarizing
The diagram below shows how two elements can be mixed together…Which is a Compound? A Mixture? A. B. C. D.
Compound
Instructional Approach(s): Students should complete the distributed summarizing questions. Students can do the questions individually or with a partner. When ready, the teacher can click the mouse to show the answers.
Mixture

6. Match the Picture to the Description
Compound of 2 Elements
Mixture of Molecules
Element Molecule
Compound of 3 Elements
Instructional Approach(s): The teacher can have the students complete this individually at their desk, with a partner, or call six students to the front to identify the correct answers. When ready, the teacher should click the mouse to show the answers starting with the first picture and working down to the last picture
Element/ Atoms
Mixture of Atoms

7. Instructional Approach(s): Students can work individually or in small groups (2-3) to complete the matching pairs activity [linked on the matter resource page]. The teacher should go over the answers with the class when all groups have had time to complete the activity or give groups a copy of the key when ready to check their own answers.
