  1. Unidentified Aquatic Organism An investigation to identify the organism, algae or water mold fungi, present in a water sample http://www.brainpop.com/science/scientificinquiry/scientificmethod/

  2. ALGAE or FUNGI ???

  3. FUNGI

  4. Water Molds

  5. Water Molds • More similar to animals • Eat leaf litter in stream beds • Attach to leaves SINK • Intake O2 and exhale CO2 • Live in flowing fresh water streams • Live on stream beds (bottom) • Reproduce by spores • Microscopic

  6. ALGAE

  7. ALGAE • More similar to plants • Need nutrients like Nitrogen (NO3-, NO2-) • Make their own food PHOTOSYNTHESIS • Need SUNLIGHT • Intake CO2 and exhale O2 • Reproduce by dividing • Live in calm fresh and marine waters • Float near surface • Microscopic

  8. You received a water sample from research scientist Jay Beebs X

  9. 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!?!?

  10. Your task! • 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 Who am I? Who am I?

  11. ALGAE FUNGI • Make their own food • Float • Intake CO2 • Prefer calm waters • Live in surface water • NEED light • Reproduce by dividing • Need Nitrogen BOTH • Eat leaves • Attach to leaves/sink • Inhale O2 • Live in flowing water • Live on stream bottom • Reproduce with spores • Live in freshwater • Microscopic • Shape
