Carbon
Carbon is the element of ?
Life
T/F Organisms inhale CO2 and exhale O2?
False
various answers
What should every lab report start with?
Title and/or introduction
Gases in the atmosphere that trap heat near the surface (ie- CO2)
greenhouse gases
Places where carbon is stored over time like oceans
Carbon stores / sinks
Which process converts solar energy and CO2 into sugars?
Photosynthesis
Bromothymol blue
What is the correct formatting of title?
Bold or underlined
The movement of carbon in the different spheres of the Earth through abiotic and biotic factors.
Carbon Cycle
How is carbon stored in the atmoshphere
CO2
Which process converts glucose and oxygen into CO2, water, and ATP ?
Cellulare Respiration
Describe why the pH changed when students exhaled into the bromothymol blue solution
answers vary - must include carbonic acid
Procedures should always be?
Step by Step, listed, and numbered
List the 3 spheres of the earth
Biosphere
Geosphere
Hydrosphere
T / F Carbon is found in all living things?
True
When students exhaled, carbon was transformed from _____ to _______ ___________ in the solution.
CO2 to carbonic acid
data table
Why are decomposers critical to the carbon cycle?
they help break down dead materials from animals and plants in an ecosystem. By doing so, they release carbon dioxide into the atmosphere. This helps plants photosynthesize by using the free carbon dioxide roaming in the atmosphere.
What's happening on Earth that affect the release of CO2?
Climate Change
Increases CO2
Deforestation, Combustion (fires and fossil fuels), Ice Caps melting, etc.
What does ATP stand for?
Adenine Triphosphate
Describe (if the lab was perfect and not errors existed) what the results would look like and WHY.
Answers vary.
What should be in the discussion of your lab report? (4 things)
- Provides a detailed explanation of results, connecting observations to photosynthesis and pH changes.
- Addresses whether the hypothesis was supported or not, with evidence from the results.
- Discusses possible sources of error and how they could be mitigated.
- Connects findings to broader biological principles, such as the carbon cycle or energy flow in ecosystems.
What is the difference between biomass and fossil fules?
Biomass- renewable organic material (ie. wood)
Fossil Fuels- coal, oil, or natural gas that are made by decay of plants and animals NON-renewable
