10/4 GOALS: EXPLAIN THE DIFFERENCE BETWEEN A SCIENTIFIC THEORY AND A SCIENTIFIC LAW DESCRIBE THE MAJOR BRANCHES OF SCIENCE 10/4 Focus Question: How is a scientific theory different than a law? SCIENTIFIC THEORY • A well tested explanation for a wide range of observations or experimental results SCIENTIFIC LAW • A statement that describes what scientists expect to happen every time under a particular set of conditions. THEORY OR LAW • There is a direct relationship between volume and temperature at constant pressure: as temperature increases volume increases. THEORY OR LAW • • 2 E=mc (Energy = mass x speed of light squared) THEORY OR LAW • Plate tectonics explains the movement of the Earth's plates and also explains the cause of earthquakes, volcanoes, oceanic trenches, mountain range formation, and many other geologic phenomenon. THEORY OR LAW • Heat is transferred in the direction from substances with higher temperatures to substances with lower temperatures. THEORY OR LAW • Mendelian genetics states that single traits always result in a 3:1 ratio between dominant and recessive characteristics. THERE ARE 3 MAIN BRANCHES OF SCIENCE 1. Earth and Space Science 2. Physical Science 3. Life Science WHAT ARE THE 3 BRANCHES OF SCIENCE? 1. Earth and Space Science 2. Physical Science 3. Life Science ROUND ROBIN CONTEST • As a table, you must come up with as many topics as you can that are related to each branch of science. • All members of the team must take turns writing down the topics on one sheet of paper.
