Consider the Following

1. Consider the Following

2. Hypothesis – an educated guess? NO! • A possible solution to a scientific problem • What’s the fastest route to the bathroom? • Out the north door, down the hall past Miss Asselta’s, Miss Alloway’s and Miss Tori’s rooms, out the wing doors, turn right, back in the wing doors by Ms. Basinger’s room, walk 20 feet, right turn into the bathroom • A prediction of the results • Nope, too slow • Out the south door, turn left, walk 30 feet past Mrs. Dr. Grimes’ room, turn left into the bathroom

3. Theory – a hypothesis that has been tested MANY times with consistent results • The THEORY of Evolution • Man evolved over thousands of years from an ape-like ancestor called Homo australopithicus. • The THEORY of the Mass Extinction of the Dinosaurs • A huge asteroid hit the earth off the coast of the Yucatan Peninsula throwing up clouds of dust so thick that sunlight could not reach the Earth’s surface, plant-life died, animal life followed

4. Law of Nature – a universally accepted theory that has been proven over and over through-out scientific history. • The Law of Universal Gravitation • Kepler’s Laws of Planetary Motion

5. Other Laws & Theories you really should know • Big Bang Theory • Einstein’s Theory of General Relativity • Darwin’s Theory of Natural Selection • Heisenberg’s Uncertainty Principle • Archimedes’ Buoyancy Principle • Hubble’s Law of Cosmic Expansion • Newton’s 3 Laws of Motion • Laws of Thermodynamics

6. And the biggest one… • The Law of Conservation of Mass • Says that mass can be neither created nor destroyed • But can change forms

7. Amended to become… • The Law of Conservation of Mass, Matter, Momentum

8. Amended to become… • The Law of Conservation of Mass, Matter, Momentum and Energy

9. YAY!! • Why? • Because Science marches on always testing new ideas, theories and hypotheses
