Warm Up #2: August 26, 2013 What would be different about the way a poet, a visual artist and a scientist depict or know the sun? How would they communicate an understanding of our star to other people? How are these approaches different? John Donne: The Sun Rising Claude Monet: Sunrise

Correcting HW Assignments Write your first and last name on a popsicle stick. I use these to choose students to answer HW questions. You need to follow along and add to/change your answers as we go in a different color (I have tons of red pens in the box on the bookshelf). Keep all corrected HW in your “HW” divider. You will turn in all HW in a packet at the end of the unit.

1.2 Scientific Inquiry (Part I) Many people define science as a way of thinking or as an approach to problem solving. So, what is so different about this approach?

Scientific Inquiry A way of solving problems using the scientific method.

Highlight each example of one of these steps of scientific inquiry in the article and draw one of these symbols next to each. Keep the article in your “Notes” divider.

Hypothesis A hypothesis is NOT an “educated guess”. Erase that from your memory. A hypothesis is an informed prediction. A hypothesis is written as an “If-then” statement For example…..

Block 1 If I ask Joel (1) what he would put on a hot dog, then he will NOT pick the ketchup. If I ask Adin what his favorite basketball team is, he will say “The Lakers”.

Block 2 If I offer Tori(2), a marker to use, then she will choose the pink one. If I offer Carmella(2) an animal, then she will pick the cat.

Block 3 If I ask Emma(3) to choose an animal, then she will choose the cat. If I ask Madeline(3) to choose an animal, then she will choose the snake.

Theory A theory is an EXPLANATION of something in nature that is supported by LOTS of evidence. “I have a theory that you will get a part in the musical.” Um, sorry, not a theory. This is a hypothesis and you should say “If you audition, then you will get a part in the musical.”

Examples of Theories Cell Theory Big Bang Theory Einstein’s Theory of Relativity Darwin’s Theory of Natural Selection

Law Laws are NOT explanations. They don’t explain WHY things happen. They are just sentences that state what does happen, every time, in the same situations. What two laws have we learned? Do they fit this description?

Examples of Laws Law of Conservation of Mass Law of Conservation of Energy Newton’s 3 Laws of Motion: 1.An object in motion stays in motion and an object at rest stays at rest unless acted on by an outside force. 2.Force equals mass times acceleration. 3.For every action, there is an equal and opposite reaction.

Identifying Theories and Laws Notice that a law can be stated in a single sentence, while a theory could take a whole book to explain.
