TOPIC:
Organisms obtaining Energy
Daily Work Grade-  None
DW GRADE: 2 1 0
DO NOW
Q: What was the role of BTB in our Elodea Lab?
A: BTB is a pH indicator. Since CO2 is slightly acidic, the BTB changed from blue to green. This was helpful in showing us whether or not CO2 was present. Therefore, we were able to conclude whether photosynthesis had occurred or not.

3. Today’s Objectives 1- COMPARE/CONTRAST autotrophs and heterotrophs
PREREQUISITES:
1- COMPARE/CONTRAST autotrophs and heterotrophs
2- REVIEW the carbon cycle
8.1 HOW ORGANISMS OBTAIN ENERGY
1- SUMMARIZE the two laws of thermodynamics
   
2- DESCRIBE/ EXPLAIN ATP & how it works in the cell   
3- COMPARE how processes of cellular energy are related to each other

4. These should be done by test day!
Vocabulary

5. LAB: photosynthesis & respiration
PRELAB: IDENTIFY VARIABLES/ CONTROLS:
IV-INDEPENDENT VARIABLE: _________________________
DV-DEPENDENT VARIABLE: _________________________
CONTROL: _________________________
CONSTANTS:
-____________________________
ENVIRONMENT [ plant- dark/light]
presence [amt] of CO2 / O2
beaker C [ dark environment] & D [light envirnt]
# drops of BTB
amount of H2O
time [24 hrs]
size of elodea [plant]

6. LAB: photosynthesis & respiration
CONCLUSION: (1-3 bulleted statements each)
1- EXPLAIN why bromothymol blue was used in this experiment.
 -identify presence of CO2
2-EXPLAIN why the bromothymol blue indicator changed color after blowing into the flask
-bubbles contained CO2
-CO2 is slightly acidic
3- IDENTIFY the purpose of placing the Elodea in Flask A & B.
 -possibility of observing photosynthesis (presence of O2)
4-ANALYZE why differences were observed between the Elodea in the light and the Elodea in the dark.
-photosynthesis reaction STARTS with LIGHT ENERGY
-no light was present in the dark

7. LAB: photosynthesis & respiration
CONCLUSION: (1-3 bulleted statements each)
5-EXPLAIN the process of photosynthesis.
-autotrophs CAPTURE light energy
-CONVERT light energy to chemical energy
-RELEASE O2 as a “waste product”
-STORE chemical energy as glucose
6-IDENTIFY how the results demonstrate the requirements necessary for this process to occur.
-beaker A [plant/light]: BTB back to blue (more O2 present than CO2)
-beaker B [plant/dark]: BTB still green- light energy not captured to start process of photosynthesis.
7-PROPOSE possible future applications and adaptations.

8. TRANSFORMATION OF ENERGY
COMPARE the laws about how energy flows. Give EX of each:
1st LAW OF THERMODYNAMICS
2ND LAW OF THERMODYNAMICS
DEFINED
entropy-
EXAMPLE
-Law of Conservation of Energy
-Energy never created or destroyed
-Energy is transformed or converted
-Energy cannot be converted w/o the loss of usable energy
-When lost-usually converted into thermal energy
Measure of disorder or unusable energy
Food  Run
Food Chains— usable energy decreases

9. TRANSFORMATION OF ENERGY
INSERT the terms above to complete the passage:
The group that makes their own food is ______________________________.
The organisms in this group are called ____________________.
The group that must eat other organisms for food is _______________________.
Some organisms get their energy from inorganic substances, such as hydrogen sulfide.
These organisms are called _________________________.
GROUP B
AUTOTROPHS
GROUP A
HETEROTROPHS
CHEMOAUTOTROPHS

10. ORGANISM’S SOURCE OF ENERGY
AUTOTROPHS-
organisms make their own food
-plants/some bacteria
1-photo-autotrophs—convert light energy from the SUN to chemical energy
2-chemo-autotrophs—make food with chemicals
HETEROTROPHS- organisms ingest food to get energy -animals
Black smoker- Atlantic ocean

11. TRANSFORMATION OF ENERGY
SEQUENCE the flow of energy from the SUN to heterotrophs
-PLANTS/AUTOTROPHS [ capture energy from the SUN]
-CONVERT light energy to CHEMICAL ENERGY
-chemical energy STORED [glucosecarbohydrates]
-HETEROTROPHS obtain chemical energy by EATING autotrophs/heterotrophs]
