« Review and Test | Main | Lichens Links »
Today we prepared our lichen samples for identification and placement in our class herbarium. All samples should have the location (latitude and longitude) as well as substrate listed on the outside of the envelope. Students also viewed their samples through the stereoscopes and attempted to use the dichotomous keys provided. We will continue our investigation and classification of our samples next week (on our field studies day) as we learn some of the vocabulary associated with their identification.
The classes who brought popcorn set up an experiment to compare different water samples for the growth of water mold (actually fungus like protists). Six types of water were used: creek water, tap water, bottled water, aquarium water, old aquarium water, and water from the tank that does not yet have fish. These organisms are oomycetes and the experiment and information can be found at the following link. It will take a few days for us to see any growth. Check out the link below even if you have not yet set up an investigation. There are some good ideas there for other investigations. For homework, please finish reading about fungi in your text (233-242).
