Learner Profile – Thinkers

Enter the classroom silently and find your seat.

1. Take out pencils, HAWK card, agenda, and metals, non-metals, and metalloids notes (6 properties boxes)

2. Everything else gets put by the back wall

3. Write down homework (Finish packet and textbook pages 64-73) in your agenda.

4. Pass your agendas to the front

5. Do Now

6. Wait silently for instructions

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.

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.

Chemical Changes• Substances that make up the

matter change into other substances with different chemical and physical properties.

• A new substance is formed.

• Examples: Precipitate (solid) formed, temperature change, color change, gas formation, production of light

• Non-examples: dissolving, state of matter change, size change.

Evidence of Chemical Change1. 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

Take a Stand

• I will read examples and non-examples 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.
