Welcome to 8th grade science! This year, we will cover motion, forces like gravity and friction, density, buoyancy, properties of matter, atomic structure, and acids & bases. Join us to learn through readings, discussions, notes, hands-on activities, and assessments. Materials needed include a binder, paper, colored pencils, ruler, calculator, and more. Get ready to be graded on tests, quizzes, projects, and daily assignments. Follow steps to success: be prepared, ask questions, review daily, create study materials, seek help when needed, and avoid last-minute cramming. Are you ready to dive into the exciting world of science?

MOTION • Speed • Distance divided by Time • (meters per second) • Velocity • Speed in a given direction • (meters per second, south) • Acceleration • Change in velocity • (meters per second per second)
Graphing these concepts • For example…
FORCES(A Push or a Pull) • Types of Forces: • Gravity • Friction • Normal • Elastic • Compression • Tension
Newton’s Laws of Motion First Law: Inertia Second Law: F=MA Force = Mass times Acceleration Third Law: Action/Reaction
Density/Buoyancy • Density: The amount of matter in a given volume of a substance. • Density = mass divided by volume • Buoyancy: An upward force exerted on an object by the surrounding fluid.
Properties of Matter • Ways to describe matter; color, texture, shape, size, temperature, etc. • States of Matter: • Solids, Liquids, and Gases • Changes in Matter: • Physical Changes • Chemical Changes
Atomic Structure • Atoms • Nucleus • Protons • Neutrons • Electrons • Periodic Table Show Pop-Up Book
Acids & Bases • Characteristics of Acids: -Taste Sour -Corrode metals -pH less than 7 • Characteristics of Bases: -Taste Bitter -Feel Slippery -pH greater than 7
Astronomy • All of the Laws of Physics also apply in Space so, what you’ve learned about the laws of Motion, Forces (gravity), Density, Buoyancy, Properties of Matter, Atomic Structure, and Acids & Bases help to fully understand the structure of the Universe.
How we will learn • Reading the textbook • Discussions • Taking notes • Answering questions in workbook • Drawings • Flashcards • Answering questions in textbook • Lab activities • Atom pop up book
Assessments • Quizzes • Tests
Materials needed for class • 3 ring binder (1 ½ inch) • Loose leaf paper • Colored pencils • Pencil sharpener with cover for pencil shavings • Metric ruler • Sheet protectors • Calculator • Highlighter • White-out • Blue or black ink pen
How we will be graded • Total points • Tests (40-50) and Quizzes (20-30) • JQ’s (10 per set) • Atom project (50) • Daily assignments/homework (4-10)
Steps to success • Be prepared each day with all of your materials • Pay attention! Stay focused!! • Ask specific questions during the lesson if you are confused
Steps continued • Be aware of any confusion regarding assignments and ask me to help you to clear up your confusion. • Be thoughtful and thorough when doing assignments and finish them on time.
.. • Go over the information each day for 5 to 10 minutes to keep it familiar • Notes, textbook pages, workbook pages, JQs, and worksheets • Create your own favorite study materials like flashcards, drawings, outlines • Attend study halls if still not confident about material. • Never wait until the last minute to review for a test.
