Visit my website BEFORE you ask me what you missed in class. If the absence is excused… – A HW assignment is due by the next class. – A quiz must be made up before the next class. – A test will be made up on the Tuesday following the test. If the absence is unexcused… 1.Don’t ditch my class. 2.You get a ZERO for the missing HW, quiz, test!

Time Issues – The weekly lab quiz will open Friday at 7:30 AM and close on Monday at 3:00PM. – Moodle quizzes will not be excused or retaken without SERIOUS extenuating circumstances Vocabulary – Vocabulary words will be assigned throughout the semester. – You will be graded based on how well you complete a vocabulary word! Log-In Issues – If you not sure about your log-in, ask! – USER NAME = first initial and last name – PASSWORD = student id # – If you need Moodle help, there is a review session after school on Thursday and Friday of this week ONLY!

You are required to make a weekly post summarizing what we have completed at the end of each week. This should be a thought out reflection with no spelling mistakes that lets me know that you know what happened in class. This is also a resource for you to use if you missed class for whatever reason. This is a weekly participation grade!

1. Learning Goal a.Transition to Unit 3: Energy & the Hydrosphere b. Understand that there are certain physical properties of water that influence the movement of energy in the hydrosphere. 2. Homework a. Moodle Pre-Unit Assessment b. Moodle Glossary c. Blog sign-up 3. In-Class a. Physical Properties of Water

HydrosphereThe Sun Atmosphere

First Law of Thermodynamics Energy can not be created or destroyed; Energy can be transferred between a system and its’ surroundings; Energy can be accounted for in different forms. Conservation Laws Mass/Matter/Energy can not be created or destroyed
9
Forms of Energy Nuclear Radiant Thermal Chemical Mechanical Potential Kinetic Electrical States of Matter Solid Liquid Gas Ways that energy travels – Convection – Conduction – Radiation
10
Efficiency Energy transfers are never 100% complete The “lost” energy is accounted for as “waste” heat. Calculating Efficiency Little #/big# *100

H 2 O It stands for 2 hydrogens (H 2 ) 1 oxygen (O) http://www.rmi.org/images/article/4Kids_H2OMolecule.gif
12
Water is an example of a polar molecule because, though it is not charged like an ion, its ends carry charges because of unequal electron sharing (+) (-) O H H Cl (-) Ion Polar Molecule
13
Solid Called ice It is less dense because it has more volume than liquid water It will float on liquid water
14
Liquid Called water Most common form of water All living things require it Gas Called water vapor Very important to help monitor the earth’s temp Energy is required to change H 2 O from a liquid to a gas
15
The MOVEMENT of water molecules increases as TEMPERATURE increases. This motion breaks the COHESIVE BONDS between the molecules, and the water changes from a solid to a liquid to a gas.
16
Amazingly water is the only substance on Earth that can be found in all three states of matter naturally. Liquid water is the most abundant form
