Your goal is to find out about the life cycle of our star, the Sun. Along the way, you will encounter HR diagrams, comparisons to our own life cycle, and stars that make our own Sun seem like a weenie. When you get done, I will expect a product (a flip book or another idea of your own choosing) that shows me what you have learned.
Life Cycle
Chandra Life Cycle
Questions that must be answered:
a) what is the life cycle of our star, and what does each step MEAN?
b) what is a supernova?
c) will our sun become a black hole? What is a black hole?
d) how does mass affect the life cycle of a star?
e) where does the matter in a stellar nursery come from?

Answer, Block 3 Questions
Carbon dioxide is made by : cats breathing, plants photosynthesizing, bikes moving, coal sitting in a pile.
Water vapor condenses into: lightning, rain, grass, clouds
Evaporation is when: rain falls from the sky, water turns into a gas, gas turns into clouds, all of the above
When carbon is used and resused it is called: the nitrogen cycle, the carbon cycle, the water cycle, global warming
Reusing paper is: climate change, greenhouse effect, an impact on the carbon footprint, more effective than cloth bags
The nitrogen cycle has to deal with the transfer of: water vapor, decay of organism and their absorption by plants, formation of oxygen and photosynthesis
The heat of the sun causes water vapor to: bubble, evaporate, move more slowly
Which is not a fertilizer in the nitrogen cycle: animal waste, photosynthesis, decay products, anhydrous ammonia
Which will have the biggest effect on decreasing your carbon footprint: driving, using plastic bags instead of paper, keeping a tv with a remote, carpooling
When water vapor falls to the ground, it is called: evaporation, condensation, precipitation, greenhouse effect
When farmers fertilize their fields, they are impacting which cycle: nitrogen, carbon, water, global warming
Respiration happens in which cycle: nitrogen, carbon, water, global warming
Lightning affects what cycle by transferring a product to a different sink: water, carbon, tree,nitrogen
What cycle is NOT affected when we breathe? water, carbon, nitrogen
Animal waste is able to be used as: compost, fertilizer, fuel, all of the above
List 3 ways carbon is released into the air from other sinks. breathing out (respiration) from living things, burning fossil fuels, leaching out of water that gets too hot
What is the biggest producer of CO2 into the air in the carbon cycle? ducks,grass, people,power plants
How does global warming affect you? temperature extremes, how much CO2 in the air, a rise in the ocean, not at all, all of the above if it gets hot enough
Why can sunlight get in but not get back out of the earth's atmosphere with the greenhouse effect? the waves are shorter on the way back out to space, the waves are longer on the way back out to space, the waves get trapped in carbon sinks in the water
If CO2 levels rise over time on data collection station, is this evidence for global warming? WHy or Why not? This is pretty conclusive evidence for the greenhouse effect. If there is a correlation between the greenhouse effect and the global climate change, we should be seeing bigger hurricanes, stronger tornados and extremes in winters,summers, and water events like floods.

Answer, Block 1 Questions
Does global warming exist? Why or why not? You can argue this both ways, depending on your belief in the accuracy of the data.
What are 3 things you can do to reduce your carbon footprint? Walk instead of drive, grow a garden, switch to fluorescent lightbulbs, compost. The possibilities are endless
List 3 types of carbon sinks. The ocean, limestone, unburned fossil fuels, plants
What is an example of a transfer mechanism? Burning, eating a plant, heating a carbon dioxide sink
What is climate change? An effect on the world around us that results in temperature extremes that are either cold or hot.
Draw a picture of the greenhouse effect. Show short waves coming into the earth from the Sun, being reflected as longer waves, and not being able to get through the CO2 in the atmosphere
What is the major greenhouse gas? CO2
Which cycle is most important? Without a balance of all the cycle, we die.
What cycle is affected by decay of organisms? nitrogen cycle
What is an advantage of driving a hybrid car? you reduce your CO2 emissions
Fossil fuels affect the _________ cycle the most. carbon
Can you stop climate change? Explain Climate change is most affected by the carbon cycle, so you need to radically stop CO2 emissions
List three nitrogen sinks. dead plants, soil, growing plants, which take up fertilizer
Who contributes most to the nitrogen cycle wastes? waste products, such as manure, are produced by living people and animals.
