"Oobleck" still holds some surprises

Dense drops of oobleck with high shear rates spread out like a liquid before stiffening into a solid.

Today in the classroom:

First year chem is going to some quantitative analysis of hard water levels by observing bubble formation. They'll sample three sources around the building and compare with distilled water.

Second year chem is coming off two days of state testing. We'll do some whiteboard work with conjugate acid/base pairs and writing out reactions. We'll also calculate concentrations/pH/K values for practice.

The wonderful PhET team at UC Boulder has released a new sim for the model of the hydrogen atom. There is a ton packed into this...I need to take time to look through it for next year.

👃🌍 Rising temperatures and biodiversity loss are shifting the chemical composition of the world's odors.

Scientists and historians are documenting how these changes lead to the extinction of natural #smells like frankincense and the scent of clean #snow. This shift impacts human cultural heritage and the sensory systems #animals rely on for survival.

Earth's Smells Are Disappearing Because of Climate Change, and It's a Vast Cultural Loss

A triple threat of pollution, extinction and warming temperatures is altering the way the planet smells. Scientists are only beginning to understand the stakes for humans

A happy birthday to my chemical romance singer Gerard Way.

Today in the classroom:

First year chem will do some warm up with vocab about solutions (solute, solvent, etc). We'll do a brief molarity recap and then use a PhET sim to relate calculated concentration with saturation. It's a good blend of calculation and observation to help them connect qualitative and quantitative evidence.

No second year chem again today because of state testing. We'll be back tomorrow.
