Title: SCIENTIFIC LABORATORY
Description: A study of the cell, the fundamental unit of biological structure and function. An introductory section on bioenergetics and biochemistry lay the groundwork for the consideration of the cell through a modern interdisciplinary approach. The course examines the ultrastructure of the cell and of the most universal cell functions: transport, cellular respiration, photosynthesis, cellular reproduction, and protein synthesis. Lecture themes are illustrated in the laboratory. 3 hours lecture/2 hours laboratory

Report on the Scientific Laboratory
Introduction: This laboratory exercise had two purposes
...
Second, it introduced us to
collaborative learning
...
Experimental Procedure
Step 1: Making Observations
Similar: Both test tubes A and B have a clear color
...
Both test
tube A and B turn blue when shaken
Dissimilar: Tube A has less substance than test tube B
...
One test tube is labelled A
...
Test tube B returns to a clear color after being shaken and put back into a resting position
...
Shake test tubes
2
...
Alternate Hypotheses Proposed by The Class:
1
...
Test tube A and B are different
Step 3: Testing the hypothesis/data and observations
When test tubes A and B are placed in the beakers and put on the hot plate, the colors change for
both test tube A and B
...
Both test tubes A and B had the same reaction
...
Both substances had the same
temperature of 21 degrees Celsius when not heated
...
The same color reaction occurs as well
...
When heated together it
reaches 73 degrees Celsius
...
But my individual hypothesis was accurate
...
I have proven my individual hypothesis to be correct because the temperature of both substances
was the same at 21 degrees Celsius at resting point
...
Respectfully, both A and B went from clear in color to a
dark brown color after being heated
...
Substances A and B
were able to reach the same temperature of 74 degrees Celsius after being heated
...
A variable is what scientists
change in the experiment
...
This is our variable because it was changed to fit our experiment
...
Two distinct variables that could have affected the formation of the hypothesis are the amount of
time we kept the substances in the beaker on the hot plate
...
Another variable could be how soon we took the temperature reading of
the substances after they were heated
...
The temperature was higher by 1 degree when both substances
were mixed together
...
