Title: ANIMAL OR PLANT CELLS? A SCIENTIFIC INVESTIGATION
Description: A scientific experiment for 7th-9th graders. The experiment was about investigating someone's murder and we had to find out if the tissue was plant tissue or human tissue. It includes pictures, conclusion, hypothesis, problem, experiment description, data analysis.

Animal or Vegetal Cells?

{date}
Experiment Description
First, we get the vegetable burger sample from the husband’s house
...
We then examine the samples to see what kind of cell it contains
...
Data Analysis
Even though both, potato and onion are plants their tissue cells are very different from
each other
...
Meanwhile, the potato cells were
smaller and variable in size and are shaped like an oval/rectangular
...
We
could not see clearly any shaped cells in the cheek tissue
...
We could clearly
observe the cells are separated by the extracellular matrix
...
Meanwhile, with the methylene blue we could see even more clearly the different shapes and
sizes of the cells from the tissue samples
...
The type of tissue that was used as evidence for the case turned out to be a plant tissue
...
The cells that were analyzed
looked exactly like the sample of potato tissue we observed
...
Court Report
Different types of tissues were used to compare the evidence tissue that was recovered by the
Crime Scene Technicians in the suspect’s home refrigerator
...
They compared each tissue to each other
and to the evidence
...
The cells that were found on the tissue’s evidence looked
exactly as the potato tissue cells that were analyzed
...
Therefore, the analysis made concludes
that the suspect is innocent
...
Onion:
a) 25 mL of 1:10 dilution of IKL solution
...
Potato:
a) Original evidence with no chemicals added
...
c) 25 mL of 1:10 dilution of IKL solution and 25 mL of 1:20 dilution of 1%
methylene blue
...
a
b) 25mL of1:10 dilution of IKL solution
...
One of the scientists’ DNA (Cristian)
a) The original DNA with no chemicals added
...
b) 25 mL of 1:10 dilution of IKL solution and 25 mL of 1:20 dilution of 1%
methylene blue
...
c) 25 mL of 1:10 dilution of IKL solution and 25 mL of 1:20 dilution of 1%
methylene blue
...
We learned how to watch
evidence under a microscope and what chemicals to put in it
...
We saw
potato, onion and meat so we could compare the difference between animal and vegetal cells
...
