- Some may say the glitter/water mixture that can be streaked to obtain “isolated colonies” onto a homemade gelatin petri dish
- Others will say the shipping box itself, which once punctured a few times will act as a “tube rack”
- Most will agree it is the foldscopes (https://www.foldscope.com/), a paper microscope that once hooked to your phone can achieve 1000x magnification (I have attached my pictures of bakers yeast and sweater fuzz)
- But no, the crown jewel was created last night by my genius wife. By using our kitchen microplane we shaved 40 different colors of crayons into a container. We then tixed in water and aliquoted into 1.5ml tubes. A circular piece of paper is then cut and placed inside of a petri dish. This mixture can then be poured over the plate by the student to create a diverse set of “colonies.” Students can then pick and patch these using the provided “sterile” toothpicks onto a 32 grid on another petri dish–something that is done in the lab to begin to find antibiotic producing bacteria.

Jacqueline Van Hoomissen, biology, would like to send a special thank you to all students and faculty who participated in the annual Science Night on Tuesday, November 19, at Holy Redeemer Catholic School in North Portland. The event was a great success and there were more than 66 undergraduate student volunteers from biology, chemistry, physics, education, and engineering. Undergraduate science education outreach students and faculty from Portland State University, Portland Community College, and Reed College, as well as volunteers from Saturday Academy, also took part.
Science Night is a fun-filled education evening full of hands-on science learning activities created by undergraduate students. This is the fifth year of the University’s Science Night and organizers would love to hear from anyone who is interested in getting involved. The final Science Night for the 2013-2014 academic year will take place in April; please contact Van Hoomissen at email@example.com for more information or to sign up to participate.
