An investigation to identify the organism, algae or water mold fungi, present in a water sample
Unidentified Aquatic Organism
http://www.brainpop.com/science/scientificinquiry/scientificmethod/
ALGAE or FUNGI ???
FUNGI
Water Molds
More similar to animals
Eat leaf litter in stream bedsAttach to leaves SINK
Intake O2 and exhale CO2
Live in flowing fresh water streamsLive on stream beds (bottom)
Reproduce by spores
Microscopic
Water Molds
ALGAE
More similar to plants
Need nutrients like Nitrogen (NO3-, NO2-)
Make their own food PHOTOSYNTHESISNeed SUNLIGHT
Intake CO2 and exhale O2
Reproduce by dividing
Live in calm fresh and marine watersFloat near surface
Microscopic
ALGAE
You received a water sample from research scientist Jay Beebs
X
Upon initially observing these organisms the characteristics are the same…
Came from a freshwater sample
Similar shape/ morphology
Microscopic Similar size
You know that these organisms are either fungi or algae…..but how will you determine their identities!?!?
Using the information you learned about water mold fungi and algae design a scientific experiment to determine the identity of the organism in your water sample
Your task!
Who am I?Who am I?
