Compare and contrast independent variables and dependent variables. 5. Name the four properties of water and how they help life. FIRST FIVE CHECK Pick up your materials. Find your seat. Organize your desk and prepare for class. Write down homework. Begin Do Now.

DO NOW Answers What does DRY in dry mix stand for? The dry in dry mix stands for dependent variable, responds to change, y axis. 2. What does mix in dry mix stand for? The mix in dry mix stands for manipulated, independent variable, x axis. 3. When would you use a line graph? You would use a line graph when tracking one change in response to another change or when plotting change over time.

DO NOW Answers 4. Compare and contrast independent and dependent variable. The independent variable is what the experimenter MANIPULATES and the dependent variable is what the experimenter MEASURES. 5. Name the four properties of water and how they help life. Cohesion/Adhesion – Capillary Action, Surface Tension Expansion Upon Freezing – Ice Floats Universal Solvent – Nutrients in your body. High Specific Heat – Water helps maintain homeostasis.

VERBAL DRILLS Name a part of a graph. Title, x axis, y axis, scale, key. Independent variable… Manipulate Dependent variable… Measure What is the structure of water. H20 What is our class motto? BE UNCOMMON

Biogeochemical Cycles Ms. Parton Environmental Science Biogeochemical Cycles

Big Idea #1: What are the spheres of Earth? What does the suffix –sphere mean? Round 3-D Object, like Earth! What does the prefix hydro– mean? Water What does the prefix atmos– mean? Vapor or Air What does the prefix bio– mean? Life What does the prefix cryo– mean? Cold What does the prefix ge0– mean? Earth/Land WORD DISSECTION

Big Idea #1: What are the spheres of the Earth? Hydrosphere = All water on Earth. Atmosphere = All air/vapor on and around Earth. Biosphere = All living things on Earth. Cryosphere = All the frozen parts of Earth. Geosphere = All land on Earth.

Today we are talking about BIOGEOCHEMICAL cycles which describe the cycling of matter through the spheres of the Earth. Literally, biogeochemical cycles are CHEMICAL elements that cycle through the living (bio) and nonliving (geo) parts of the environment. These cycles occur around you each and every day and are critical to the continuation of life on Earth.

What are these biogeochemical cycles? They may seem familiar… The Water Cycle The Carbon Cycle The Nitrogen Cycle & The Phosphorus Cycle

Matter is neither created nor destroyed – it only changes!

Big Idea #2: What is the water cycle?

Big Idea #2: What is the water cycle?

Big Idea #3: What is the carbon cycle and nitrogen cycle?

Big Idea #3: What is the carbon cycle and nitrogen cycle?

Big Idea #3: What is the carbon cycle and nitrogen cycle?

Check for Understanding What is the difference between a sink and a source? True or False. New water is being made everyday. How do the biogeochemical cycles relate to environmental science?

What are red tides and dead zones? With your lab partner, read through the article. As you read, do the following: Define red tide and dead zone. List any causes of red tides and dead zones mentioned in the article. Identify the relationship between nitrogen and red tides/dead zones that is suggested by the article. What data is needed to support his claim?
