Tried out this little handheld microtome. With a little practice I made some nice slices and tried my hand at dyeing. Okay! I think I’m ready to introduce this to my biology students.

This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

If your class doesn’t have gas piped in (mine doesn’t), butane canisters are an effective option. Add a clamp for security and you’re good to go! #EduSky #ChemSky

An issue we're seeing at all levels of university is that many students are simply refusing to do *anything*. They aren't reading the syllabus, aren't following assignment guidelines, aren't engaging with material, ignoring deadlines. And this might seem like old news, but it truly has ramped up.

It’s a tradition that I ask my “Physics III” class to create some memes about our class material. It’s *also* a tradition that they’re super good at this. Please enjoy, like and share! 🧪 (I promised my students extra game points if this goes nano-viral!) (Front pic is my own entry.) 1/17

Euphemistic language is a tool often used to sanitize grave injustices. When referring to the WWII incarceration of people of Japanese ancestry, it is important to use the correct terminology: concentration camps, not relocation centers; forced removal, not evacuation; citizens, not non aliens.

Kids often balk at reading long passages. Here, each student read a few paragraphs and chose 3 phrases that resonated with them. Each read one phrase aloud to the class, then they wrote their favorites around the article taped to paper. Taped it to the door for all to see. #EduSky

Newspaper article “Americans will throw out 316 M pounds of food on Thanksgiving” taped to an easel-sized paper. Quotes from the article, written by 10th grade biology students in colored pencil, surround the article.

Because the Sicilian Norman-Arab style doesn't represent a specific national identity, it stands out in the modern imagination. It represents a path not traveled: what if we were taught that accommodation and fusion were glorious alternatives to crusades?

Geometric patterns from the cathedral at Monreale. These tile works take mosaic into the realm of mathematical geometry, and show that even the most fascist possible color palette (white, red, black and gold) can represent combination and integration rather than separation and distinction

In 1942, at the height of the Second World War, Alfred Eisenstaedt photographed sweethearts bidding each other farewell before the men depart for war, not knowing if they'd ever return. These candid shots give us a glimpse of what average Americans wore. Let's look at the details. 🧵
