Now that I know that they don't seem to survive in water or move, I'm going to continue my experiment differently. I am going to disolve sugar in one and salt in another petri dish with water. than I'll wait for the water to evaporate. (the petri dishes should now have a layer of salt and sugar) After that i am going to put the nematodes without water on top of the dried disolved sugar and salt petri dishes. I'll see how the nematodes behave on the individual petri dishes and how long they stay alive. As a check, I'll also put nematodes in a clean petri dish. | Now that I know that they don't seem to survive in water or move, I'm going to continue my experiment differently.

In the following picutres you can see how i disolved the sugar and salt | In the following picutres you can see how i disolved the sugar and salt. In order for the water to evaporate faster, i then put it an a heater. | ||
'''Remark:''' To prevent the petri dishes from beeing swapped, they are labaled! | |||

I will contiune with the experiment as soon as the water has evaporated | I will contiune with the experiment as soon as the water has evaporated | ||
