  • setting up tardigrades

Experiment #2

(see for the first experiment previous class)

1st 12 well plate -- potassium phosphate

  • 4x euglena and potassium phosphate (0; 0,05; 0,5; 5).
  • 4x cyanobacteria and potassium phosphate (0; 0,05; 0,5; 5).
  • 4x cyanobacteria, euglena and potassium phosphate (0; 0,05; 0,5; 5).

2nd 12 well plate -- nitrogen

  • 4x euglena and nitrogen (0; 0,05; 0,5; 5).
  • 4x cyanobacteria and nitrogen (0; 0,05; 0,5; 5).
  • 4x cyanobacteria, euglena and nitrogen (0; 0,05; 0,5; 5).


Hunting for the organisms at the Ilm park

Our class visited the ponds at Ilmpark, where we collected various water and soil samples. Now, the question is: what elements do we want to focus on for study, and what should we consider introducing to our rainwater pond?

Here’s what we found:

Duckweed water

  • Freshwater copepods
  • Algae resembling Chlamydomonas

Soil samples

  • Possibly Demodex canis
  • Nematode worms

Leaf water sample

  • Algae resembling Chlamydomonas
  • Klebsormidium-like structures
  • Watercress (Nasturtium officinale)
