Final Presentation Script Flashcards
Slide 1:
Hello, my name is Tyler.
Slide 1.1:
This is our final project presentation on “Improving Copper Algae Purification Through CO2 Enhancement.”
Slide 2:
Our hypothesis is that adding CO2 will significantly impact copper absorption by algae.
The changing levels of CO2 is the independent variable and the copper concentrations is the dependent variable.
Slide 3:
First, we needed to cultivate the algae.
To do this, we placed the algae in a bowl and used a stirring machine to constantly agitate the algae using a LED light to act as sunlight.
This allowed the algae to live throughout the experiments.
Slide 3.1:
This would be repeated for all beakers and then we would wait for 2 weeks.
After the 2 weeks we would get the concentrations of copper using copper test strips and then we would compare them to the container that it came with to see the values that the colors corresponded to.
Slide 4:
Additionally, we made another data table showing the means and the percent change of copper concentration before and after.
This showed that increasing CO2 increased the average copper concentration difference.
This is also seen with the bar graph as they are decreasing.
Slide 5:
This is also supported by the F valve being greater than the F critical value.
Slide 6:
To see the actual impact of CO2 on copper concentrations, we used the other statistical results like the mean and percent change.
Looking at the data tables, we concluded that increasing the CO2, increased the mean of copper difference.
A high difference would mean that more of the copper was removed.
Slide 7:
Our research is an improvement over the current existing knowledge about CO2 being a contributor for algae growth by showing how this can also help reduce heavy metals in solutions.
Slide 8:
Our project turned out what we expected it to be because of the research that we had done.
Slide 9:
Some works relating to algae involve using CO2 to help cultivate and grow the algae itself.
This can be seen with the decrease in copper concentrations as more CO2 was added to the beakers.
Slide 10:
Some questions that we had were:
“Do you think that we should use different kinds of algae or different kinds of metal powder?”
and
“Do you think that different types of water (tap, spring, mineral) would affect the after concentrations of copper?”
Slide 11:
And this is our final presentation on “Improving Copper Algae Purification Through CO2 Enhancement.”
Thank you.
