What is Chemistry?What is Chemistry?

Spi’s and CLE’s:• CLE 3221.Inq.3 Use appropriate tools

and technology to collect precise and accurate data.

• CLE 3221.Inq.1 Recognize that science is a progressive endeavor that reevaluates and extends what is already accepted.

• CLE 3221.2.1 Investigate the characteristic properties of matter.

• CLE 3221.2.2 Explore the interactions

between matter and energy.

Objectives:• The learner will understand the

role of chemistry in their lives.• TLW investigate the

characteristics of matter.• TLW explore the interactions of

matter & energy.

Key Topics• States of Matter• Changes of Matter• Evidence of a Chemical Change• Chemical Reaction/Chemical

Equation

What is Chemistry?• Chemistry is the study of

chemicals their properties, and the reactions in which they are involved.

What is a Chemical?• Chemical- any substance that has

a definite composition (everything).

What is a Chemical Reaction?

• Chemical reaction- the process by which one or more substances change to different substances.

What are the 3 States of Matter?

• Solid• Liquid• Gas

States of Matter

Solid Fixed volume

Fixed shape

Liquid Fixed volume

No fixed shape

Gas No fixed volume

No fixed shape

Put this chart at the top of page 6 in your scientific notebook.

What are Changes of Matter?

Two Categories:Physical - Changes in which the

substance stays the same.

Chemical – substance changes into something different

What type of change is it……..?

• Cutting paper• Wood burning• Rust• Ice cream melting• Water boiling• Milk souring

Answers:• Cutting paper-physical• Wood burning-chemical• Rust-chemical• Ice cream melting-physical• Water boiling-physical• Milk souring-chemical

What are some evidences of Chemical

Changes?• Evidence that a chemical change

may be happening usually involves: 1) evolution of a gas. 2) formation of a precipitate. 3) an energy change. 4) a color change.

Evidence of a Chemical Change

Gas Evolution Bubbles form or odor

Change in Energy Change in temp. or light given off

Formation of a Precipitate

Cloudy appearance; precipitate forms

Color change Color looks different

Place the chart at the bottom of page 6 of Scientific Notebook.

Closure:• Please Be Able to tell me the

difference between physical and chemical changes when you leave the room.

Homework:• Name at least 3 branches of

chemistry(example- biochemistry).
