Conclusion
In our investigation we used test tubes to simulate
different environments, bromothymal blue to test for CO2, and a microscope
& stain to look for cells. We didn’t encounter any problems but if we could
change the way we collected data, we would separate the
different types of environments. For example, have freshwater and saltwater
with the two days we collected data on one table and have the soil and sand
with the two days on another.
The
independent variable in our experiment was the different environments that and
the dependent was the reaction the unknown had to that environment. The
controls we had included how much water was in the water environments, how much
we watered the sand and soil, and that all of our test environments were in the
same environment. By putting the unknown in different environments
(stimuluses’) we were trying to see if it would elicit different responses to
any of the environments.
I
would consider our conclusions to be a fact. This is because we did prove life
and it cannot be disproven, which is why it is not a theory because a theory
can be. From this lab I learned how to use stain and the bromothymal blue, as
well as how to set up future labs in this class.
Suki I loved reading your reflection on the project. How you explained how we learned to use tool as we went through this lab. I also liked how you mentioned how we could have done better during the lab itself. A couple things that I did not see that I would have liked to see were comments on how we performed during the presentation, also how could we have organize for the presentation better. Along with a bit more detail I on what could have worked better for the group. In contrast though you showed what we used and how we used the tools to help us. With that I fell anyone that was not aware of the lab could have read your blog and have some idea of what we were working on. Overall though your reflection was very well done.
