Is it Alive?By:Ali FazalThomas WattsAna De La Cruz

Questions we had

• Is it made of cells?• Does it react to its environment?• Does it reproduce?• Does it grow?• Does it release Carbon Dioxide?

How did we answer the questions?• Attempted to look for cells under microscope• Created different environments:• Freshwater (Animals• Saltwater (Animals)• Soil (Plants, Fungus)

• We couldn’t confirm any reproduction• Observed it in its environments• We used bromothymol blue to test for CO2

Carbon Dioxide Results• We found out that it releases CO2

Results- Cells• Not enough data for conclusive statement

Results- Saltwater• The substance had no change in saltwater

Results- Soil

•The substance had no change in soil

Results- Freshwater• Substance changed in freshwater

Tools

•We used:•Microscope•Camera•SD Card•PowerPoint•Slide Share

Conclusion• Alive• Because we noticed growth only in freshwater• Gave off CO2 which is a sign of chemical energy

Info Learned

•We learnt that bromothymal blue is an indicator of CO2• How cells look• How to stain an slide• How to make a wet slide• How to use a microscope

Questions remained unanswered•We don’t know whether it reproduced•Don’t know whether it has cells
