Chemical Commonly Found in Dry Cleaning Causing Parkinson’s Disease
According to a study published in the Journal of Parkinson’s Disease by an international team of scientists (Ray et. al), a chemical commonly utilized in dry cleaning, metal degreasing and decaffeination of coffee has been identified as a possible factor contributing to Parkinson’s Disease. According to the U.S. Centers for Disease Control and Prevention, TCE…

Symbiosis.. Or is it really?

While researching about the different interactions that exist in the Amazonian rainforest for an Environmental Science Biomes project, I came across the “symbiotic” relationship between lycaenid species caterpillars and cocktail ants. (1) The Amazon rainforest is a crucial biome to our planet, storing 76 billion tonnes of carbon while also releasing 20 billion tonnes of…

ACS Chem Club Has a Blast at the School Carnival

A few weeks ago, ACS members were fortunate enough to host their own booth for the all-school carnival held in years post-COVID. Through weeks of busy brainstorming with the team, our club eventually came to the consensus to host an interactive DIY slime booth. Selecting the price range for the slime activities was one of…

ES Summer Camp Day 13 (6/29/22)

Bacteria cultivation time! Today’s lesson was kind of nostalgic in the sense that it reminded me of my CRISPR experiments, when I failed to successfully create the perfect agar petri dishes. I remember when I accidentally over-microwaved my glass bottle, which was filled with agar powder and water, and having to remake the entire solution…

ES Summer Camp Day 12 (6/28/22)

*Mild flashbacks to my AP Chemistry video project on the exact same experiment..* Prepare yourselves for an ACIDIC adventure! Today’s class was about exploring acidities of different household liquids and beverages we commonly enjoy or use through a natural indicator found in red cabbage. Though it was difficult to explain the concept of pH and…

Different gases have different densities. Though we learn in Elementary school that we only exhale carbon dioxide, that claim is partially true. The air we exhale is composed of a variety of different gases, including carbon dioxide, so its density (0.0748 lbm/ft3) is actually lighter than that of carbon dioxide (0.1137 lbm/ft3). This week, we’re…

ES Summer Camp Day 9 (6/23/22)

Throwback to mini me in 5th grade struggling to measure the length of the food coloring pathway on my celery for my science fair project. This lesson plan was inspired by that science project, actually. If yesterday’s class lesson was on Chemistry (exploring acids and bases through explosive sandwich bags), today’s lesson was more focused…

ES Summer Camp Day 8 (6/22/22)

Finally our first experiment for the lower division students! Yesterday, the students decorated their science notebooks. While planning the experiments and lesson plans for the lower division students, who were younger than the upper division students, I often contemplated between whether to use the same lesson plans/experiments as the upper division students or to simplify…

ES Summer Camp Day 6 (6/20/22)

Sixth day of summer camp…! Similar to the lesson we had last Monday, the ACS Chemistry Club members came to visit and help out with a lab safety rule-based class. This week is focused on the lower division of the students (currently in 1rst and 2nd grade), so we had less students to teach, but…

SSC: Microscopes

For this Saturday session at the Seoul Science Center, I explained the microscope booth and also led the interactive bee microscope event. The microscope exhibit had two different types of microscopes — stereo and biological. I actually learned about distinguishing the two during this session; the location of the light source affects the thickness of…
