What do they grow on different type of bread? BIOLOGY LABORATORY NATURE OF LIVING ORGANISM AND THE SCIENTIFIC METHOD
The scientific method of different type of bread 1. Observation Bread, when kept a long time to be born mold.
2. Critical question When the bread placed on the temperature difference and spray water same amount will affect the mold or not.
3. Develop hypothesis If the bread in a low temperature or in the refrigerator will occur slow mold. # related # not related
4. Make prediction If the bread in the room temperature will occur mold faster than low temperature
5. Perform experiment Bread 3 type - normal bread - France bread - whole wheat bread Foggy Plastic box [have lid]
VARIABLE: 1. Independent variable - Temperature and type of bread 2. Dependent variable - mold occurring in bread 3. Controlled variable - spray water same amount
Experiment divide 2 group Temperature: room spray water same amount Temperature: low temperature
6. Collect and analyze data We are observe 1 week date 1 Experimental group mold occurring in bread Temperature: room No change Temperature: low temperature No change - normal bread - France bread - whole wheat bread spray water same amount
date 2 Experimental group mold occurring in bread Temperature: room No change Temperature: low temperature No change - normal bread - France bread - whole wheat bread spray water same amount
date 3 Experimental group Temperature: room - normal bread - France bread - whole wheat bread Temperature: low temperature - normal bread - France bread - whole wheat bread spray water same amount mold occurring in bread normal bread - little point of black France bread - little point of black pink and violet whole wheat bread – little point of black No change
date 4 Experimental group Temperature: room - normal bread - France bread - whole wheat bread Temperature: low temperature - normal bread - France bread - whole wheat bread spray water same amount mold occurring in bread normal bread - little point of black France bread - little point of black pink violet and green whole wheat bread – little point of black No change
date 5 Experimental group Temperature: room - normal bread - France bread - whole wheat bread Temperature: low temperature - normal bread - France bread - whole wheat bread spray water same amount mold occurring in bread normal bread - some select dark brown France bread - little point of black pink violet and green whole wheat bread – little point of black white and blue No change
date 6 Experimental group Temperature: room - normal bread - France bread - whole wheat bread Temperature: low temperature - normal bread - France bread - whole wheat bread spray water same amount mold occurring in bread normal bread - medium point of black France bread - big points of green violet and black whole wheat bread – big point of black white and blue No change
date 7 Experimental group Temperature: room - normal bread - France bread - whole wheat bread Temperature: low temperature - normal bread - France bread - whole wheat bread spray water same amount mold occurring in bread normal bread - big Lichen green France bread - big Lichen green whole wheat bread – big Lichen green No change
7. Conclusion the mold on bread experiment at different temperatures. Is at room temperature. And low temperature or in refrigerator results show that Three types of bread, place it at room temperature will have mold over very low temperatures. the observation bread in low temperature do not change.
