2. “The Wizard of Oz” OBSERVATIONS When you observe you become aware of something using one of you senses. If you see, smell, taste, or hear something, You are observing it. You simply describe something as it appears AN OBSERVATION IS A STATEMENT DESCRIBING A FACT

INFERENCE When you infer you make a Mental judgment based on observation. It requires thought AN INFERENCE IS A STATEMENT BASED ON THE INTERPRETATION OF FACTS EX: If you get up and the ground is wet, and their puddles on the ground. You may INFER it rained last night

2. “The Wizard of Oz” What the professor used: Observations Logic Process of elimination Physical model (photo) Mental model

A material representation of something Can be touched, seen, or manipulated Physical Examples: doll, globe, photo 3. Scientific Models

A mental picture or a collection of ideas or facts The thoughts you have about a topic Mental Examples: a mental picture of Jupiter; what you know about the White House

MANY observations Assume things will continue to behave as they have in the past Based on Changed to fit new info Discarded if they can’t be fixed (this is a last resort!) If not accurate

A tool to help: make observations Usefulness explain how things work make accurate predictions think of new areas to investigate

1. “Items being compared” goes along bottom (I.V.). 2. “How much” goes along side (D.V) 4.Constructing Graphs 3. Choose units (biggest number must fit but spread out data); start with zero

5. Put a title on the graph 6. Draw the dots & connect 4. Label the side and bottom

Holds planets, stars, objects, in orbit 5. Gravity Holds objects to planet’s surface Effects 1. Mass of object Depends on 2. Distance between objects

“Every piece of matter in the universe pulls every other piece of matter towards it, and vice versa.” Universal Gravity Necessary for formation of stars & black holes Measure of the pull of gravity on an object Weight

Mental model about formation of universe A huge explosion 13.7 billion years ago. 6. Big Bang Theory Gravity caused matter to come together to form planets, stars, etc.

Nuclear Fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus: Proton + Proton-  Neutron Proton + Neutron -> Deuterium ion of Hydrogen Deuterium + Proton  Helium Helium is the fuel for the stars

Big Bang Lab Confetti pieces represent the following: Blue: Proton (P +) Pink: Neutron (N) Purple: Hydrogen (H) Yellow: Helium (He)

Spheres of gas that produce energy by fusion 7. Stars Nuclear reaction Fusion Atoms fuse (combine) to form larger atoms Gives off enormous energy (heat & light)

Temperature (hot-->cool) 8.Classification of stars based on: Composition (amount and kind of material) Mass (small --> large) Age (young --> old)

Temperature (hot-->cool) Purple Blue Green Lt. Yellow Dk. Yellow Orange Red 35,000°C 3,000°C

9. White light Spectrum A combination of all colors of light “Rainbow” White light separated into individual colors

Blackline spectrum When an object is heated and glows, its spectrum shows a specific pattern of black lines Can be used to identify substances
