Here are some movies of the organisms we collected.

  1. Sand crabs respond to waves by coming out of the sand to feed on plankton. After the wave has passed, they burrow back into the sand. Here, Manu is disturbing the water to simulate a wave, so we can collect some crabs in a frisbee for our foldscope.

2. We also found some shrimp, and looked at the embryos. The embryos had an interesting slit on one side.

3. This movie shows some different cell types in an adult shrimp. We found epithelial cell layers, circulating hemolymph, and a beating heart!

4. As Manu explains here, even in a very small volume of water, we found microplastic pollution.

5. Finally, we found some female sand crabs that were protecting clutches of eggs. The eggs were beautiful when viewed with the foldscope! We could see cellularized developing embryos, and we also saw that there was some kind of mesh holding the clutch of eggs together. We aren’t sure what the fibers are made of, but it was a cool (and unexpected) observation!

Greetings from Tioman Island, Malaysia. We are the members of The World Changers, a student-run Non-Profit Organization based in Seoul, Korea. We are thrilled about making our first posting at Microcosmos! Actually, in summer of 2014, as a part of our education project in Tanga, Tanzania, we were lucky to obtain twenty pieces of Foldscope prototypes from Prof. Prakash, and we were able to teach 100 elementary kids from Pongwe Primary School. Back then, we only had a handful of Foldscopes and we could only do very rudimentary lessons with kids. This summer, we visited Prof. Prakash at his lab in Stanford University, and we learned about the community of Foldscope users at Microcosmos and what exciting projects are being done around the world. This summer, we planned to teach 30 elementary school kids and 70 high school students in Kampong Juara in Tioman Island.

Once we arrived at the school, we first started with some quick introductions and jumped straight into working with the Foldscopes. Our allocated time was only one session of two to three hours, so we did not have much time at all. We brought pre-made glass samples to let students learn how to use the Foldscopes, but then spent most of our time together exploring the local area and letting students prepare their own samples. Our goal was to spark curiosity among the students and let them discover things on their own. We also brought colored pencils and sketchbooks to let the students draw their findings.

We left behind Foldscopes at the elementary and high school with a link to the Microcosmos community. Hopefully we will see their own posts soon! We also hope to go again either back to Malaysia or somewhere else while continuing to work with Foldscopes.

Best,

The World Changers
