 This photo was taken at 8:00 pm on Friday May 10th using a foldscope and phone camera, lit by a flashlight. The distinct yellow particles (mostly clustered so difficult to distinguish) are pollen. The pollen sample was collected from Rhododendron simsii earlier the same day (5 pm) near Avery House (Caltech Campus), and mounted on a foldscope sample slide. A photo of where the sample was obtained is shown below:

 Plant species
 
 : Rhododendron simsii


 
 Magnification
 
 : 140x, pollen grain is approximately 0.007mm in diameter.


 How can the pollen be seperated/isolated so the view of distinct particles are clearer? (Perhaps try using tweezers?) #caltechbi1

 Description: A small piece of tree bark is scraped from a tree in front of the Annenberg Building in Caltech. It is a pretty interesting bark because of the color. Under the foldscope, we can see the shredded/pressed bark is in small strips.
