 The photo shows some pond scum in water taken from the BBB lily pad pond. This sample was taken at 6:50 pm on April 8, 2019. The sample was extracted from the pond using a falcon tube. The organism shown in the picture is most likely from the domain bacteria given the size and shape of the organism and the environment from which the sample was extracted. How many of these organisms live in the pond? An approximation could be made by calculating the number of organisms found in a small sample and scaling that from the volume of the sample to the total volume of the pond.

 The image shows yellow pollen particles from a white flower. The sample was collected at approximately 6:00 pm on Tuesday, May 7th outside of Braun gym (location shown in second picture). The sample was extracted by shaking the pollen onto the slide. Using a dichotomous key, the flower was determined to be a Japanese Camellia. #caltechbi1
