Teach the Teacher: What is the most adventurous thing you have ever done? • Review: Why do we have independent and dependant variables and control groups in the scientific method? Warm-up 10/2/12
Atoms • Matter • Properties of fluids • Properties of Gases • Mixtures • Chemical change • Physical Change
Physical Science 1 The Stuff that Matters
Study of matter and energy • Physics, Chemistry, Astronomy, & Geology What is Physical Science?
Anything that has mass and takes up space. What is matter?
Atom=smallest unit of matter Structure of Matter What makes up matter?
Protons • Neutrons • Electrons • Protons=positive charge • Neutrons=neutral in a car=no charge • Electrons=electricity= “-” • Nucleus contains protons and neutrons • Quarks could make up protons and neutrons What makes up an atom?
Teach the Teacher: What is one thing that would make school 10x cooler? • Review: List as many parts of an atom as you can remember. Warm-up 10/3/12
Find a partner, Pound it! • Introduce yourself • Whoever is taller goes first: looks at other person’s back gives a clue as to what the word is • Second person looks at the other person’s back and gives clues as to what the word is • Keep giving clues until the music starts, DON’T Guess until the end! • Don’t say the word on the card! (or what it sounds like or starts with) • When music starts find a new partner (can’t use the same partner more then once) Don’t Say It! (Educational Taboo)
addoms family Size of atomic particles
Matter comes in 4 different states Solid Liquid Gas Plasma Atoms atoms family What are the 4 states of matter?
Teach the Teacher: What type of car best fits your personality? • Review: What are the different states of matter (4)? Warm-up 10/4/12
Buoyancy: ability of a fluid to exert an upward force on an object Properties of Fluids
Bernoulli’s Principle • Increased speed of a fluid or gas=decreased pressure Properties of Fluids
Teach the Teacher: What was your favorite thing to do as a little kid? • Review: Draw a picture of the shape of an airplane wing, or the upward force of water on the basketball Warm-up 10/5
On the Front: • Parts of an atom • On the back: • Protons (+) • Neutrons (0) • (N&P=size) • Electrons (-) • (much smaller) Flash Card
On the front write: • Bernoulli’s Principle • On the back write: • Fast air=low pressure (light) • Slow air=high (heavy) pressure ( ) • (airplane wing)
Boyle’s Law • A smaller container of gas will have a higher pressure (if at the same temp) then a larger container of gas Properties of Gases
Plasma • Plasmas consist of freely moving charged particles • electrons & ions • Plasma is formed at high temperatures when electrons are stripped from neutral atoms
Element A substance that cannot be broken down by chemical means 90 naturally occurring elements found on Earth 20+ man made elements (nuclear bombardment) Elements are listed on the Periodic Table FORMULA = Only one capital letter Elements vs. Compounds
Compound • Two or more elements bonded together. • Bond in ratios • Water = H2O it will always have 2 hydrogen atoms for every 1 oxygen atom. • Formula= more then one capitol letters • FORMULA = more than 1 capital letter Compound
Mixture—a material made of 2 or more substances that can be separated physically. • There are 2 types of mixtures: heterogeneous and homogeneous. Mixtures
Heterogeneous Mixture—different materials can be distinguished easily. • Ex. Pizza, salad, chocolate chip cookies (mmm), pepper jack cheese • Homogeneous Mixture—substances are blended evenly throughout. • Ex. Pop, vinegar, cheddar cheese • A homogeneous mixture is also called a solution.
Mixture • Is made up of two or more substances that can be easily separated by physical means. • Mixtures do not have to have the same proportions • Two types of mixtures • Heterogeneous • A mixture where the substances can be easily distinguished • Most substances you come in contact with are heterogeneous • Homogeneous • 2 or more substances blended evenly throughout Types of Mixtures
Physical Changes • Physical changes DO NOT alter the identity of the original substance • A change in size, shape or state of matter is a physical change “3S”
Chemical Change • The change of one substance to another is a chemical change • 6 Clues that a chemical change has occurred • Color change • Bubbles (not boiling) • New odor • Heat or Cooling • Light • Sound
Chemical change happens during a chemical reaction • Never a change in the number of elements • Energy is always taken in or given off Chemical Reaction
= sugar water 8. Chemical or physical change
Review questions: List as many physical changes as you can think of (where something changes size, shape, or state but is still the same substance) (ex: tearing paper) • Teach the teacher questions: List all the cartoons you have seen more then once (ex: Sponge Bob) Warm-up 2/3/11
Vocab Poster needs: Word, definition, and picture (depending on the word). • MUST BE BIG ENOUGH TO READ FROM ACROSS THE ROOM! • vocab: matter, atom, proton, neutron, electron, element, physical change, chemical change,compound, mixture, heterogeneous mixture, homogenous mixture Vocab Sheet
