Statement of Inquiry/IB Trait STATEMENT OF INQUIRY: Everything in the universe, including us, is made of matter and elements are the building blocks of all matter. Discovering elements has helped scientists identify the things that everything in our universe has in common and the relationships we share. Discovering the benefits and harms of certain elements and compounds has helped us understand our universe and the way in which it works. IB TRAIT: INQUIRERS
10 min Quiz Silently take the 6.6A. Write your name at the top of the bubble sheet and bubble your ID number Circle your answers on the quiz AND bubble your answers on the bubble sheet When you are finished, continue sitting silently until the entire class is done.

Closing and Questions You re here, you take up space, you matter. It s just Science, man! Kid President
Demonstrations/Observations Silently observe three demonstrations. Write specific and detailed observations about what happens in your guided notes. Think about what you think these observations mean for these substances Are they the same was they were before? Has a new substance formed?

Physical Changes The change in the size, shape, form, or state of matter that does not change the matter s identity. A new substance is not formed. Examples: Dissolving, changes in state of matter, size, melting and boiling. Non-examples: Color change, formation of gas, temperature change, precipitate formation. Follow along in textbook pages 65-66
Substances that make up the matter change into other substances with different chemical and physical properties. A new substance is formed. Chemical Changes Examples: Precipitate (solid) formed, temperature change, color change, gas formation, production of light Non-examples: dissolving, state of matter change, size change. Follow along in textbook pages 67-70
Stop and Jot What is the difference between a chemical change and a physical change?

Evidence of Chemical Change 1. Formation of a gas. a. Usually in the form of bubbles or fizzing. 2. Formation of a precipitate. a. A solid is formed when two liquids are combined. 3. Color change 4. Production of light a. Combustion fire. 5. Temperature change Follow along in textbook pages 67-70
Turn and Talk Why is dissolving not a chemical change?

15 min Take a Stand I will read examples and nonexamples of chemical changes. Scholars who agree with the statement I make will stand up Scholars who disagree with the statement will stay seated.
15 min Take a Stand Then, you will turn and talk to the person next to you and defend your agreement/disagreement. I will then cold call on scholars to share out their responses.
