Talked on the first day to my students about externalization of motivation, or the overjustification effect: getting external rewards for something that we enjoy can reduce our enjoyment. When we are paid (in money or other commodities) to do something, we often shift our motivation from within ourselves to the reward system.
My general spiel is that students have been subjected to this for 12+ years in the form of grades. Kids are generally curious and delighted to learn. I'm convinced one reason why this changes into the dull-eyed stare in many college students is because they have been graded for demonstrating their learning for over a decade. Grading their academic work (among other dynamics) has shifted their intrinsic drive to learn toward grades instead of the learning itself.
It is very difficult, in this context, to keep one's love of learning alive.

Ten years of teaching GIS and remote sensing, and the hardest concept is still the same one: students learn buttons, not data models. Once someone truly gets what a raster is — a grid of measurements with a CRS stapled on — half of remote sensing follows on its own.

Picture a bright red apple. Most people can do this easily. They imagine the apple's shape, color and shine. But for others, the image is vague and blurry or they "see" nothing at all. This is known as aphantasia—a "blind mind's eye."Andrew J. Martin (Phys.org)

Back to pen and paper: Norway bans AI from primary schools.

Initial thoughts on using ZnCl2 instead of NaOH:
- I like that cleanup is much easier - no need to neutralize before disposing.
- It seems to take longer to plate. Maybe because the zinc ions aren't reduced as easily?
- I'm using 1M ZnCl2, perhaps I need to increase that concentration to help provide the ions for plating.
Today in the classroom:
First year chem are making a brass alloy using pennies and zinc. We'll chemoplate the penny with powdered zinc in ZnCl2. Then, we heat the zinc coated penny to create a shiny "gold" penny. This is a good lab to show students that mixtures can be solids.
Second year will explore how pH changes with H+ ion concentration. They'll dilute some samples, collect pH, then compare their molarity with the calculated pH value.
Just Think! I've got flowers and gardening on the brain!

Today in the classroom:
First year chem will do Lewis diagrams for ionic compounds. They'll draw neutral atoms and then use arrows to show which atoms lose electrons and where they go. This will baby-step us into writing ionic compound formulas.
Second year chem is wrestling with their first lab report for the semester over their Charles' Law data. They'll have today to finish graphs and submit. We'll do partial pressures next week & collect gas over water.

Learning is a process of trying, experimenting, imitating, practicing, and asking lots and lots of questions.
That's why children are -- before we train them out of it -- such great learners.
We, too, can gain that back by re-learning what we have been trained out of: experimenting, imitating, practicing, and asking lots and lots of questions.
