1. Is It Alive
Group 4

2. Our Unknown:

3. Figuring out it
was alive:

4. Things we wanted to test
for:
• CO2 emmision?
• Does it react in enviroments?
• Does it have cells?
• Does it grow?
• Does it reproduce?

5. Testing
We put a pinch of our unknown in a tube of salt water,
and a pinch in a tube of fresh water. We wanted to
test how it would react to being in the water, or to see
if it would grow
We also added
bromothyle blur to both to
test if it releases CO2

6. Des it release CO2?
Fresh Water:
Day one: Day three: Day four:

7. Salt Water:
Day three:
Day one: Day four:

8. Data
We could not observe the growth of the
substance in the soil. But it could just
need more time to grow.

9. Does it grow: water edition
We looked at how the
unknown reacted to the water
every day.

10. Results:
Control:
fresh
salt

11. Does it have cells?
We observed some cells,
that we think may be cells,
and they mat be too small to
observe with accuracy.

12.  We were not able to test reproduction.

13. Is it alive?
From our data, and though we cant be sure we believe that
our substance is alive. If we could observe the substance for
a longer period of time then we could come to a certain
conclusion, but because it releases CO2, and because it
seems to grow in water, we think it is alive.
