So for the science teacher with a few bored kids in the last row...



I understand this could bring new challenges as you seek new employment, so I don't expect it to be taken literally.

But it might provoke other ways to open the mind so people will learn, ways that may be a slight bit out of the mainstream.

2. There is no conservation of mass.

There is a conservation of energy, which is related to mass by E=mc^2. However, mass is not conserved, energy is.

I'm no fun at parties.

Besides, it strikes me as highly appropriate to be writing about cleaning hash and conservation of energy in the same paragraph.

Thank you.

4. One has to consider in the munchy factor.

That alone will tell one that there is no conservation of mass. Mass grows under that operation, which BTW does non-commute.

Kief is product of the separation of the crystals from the green plant matter. That's my understanding of it.

7. The bored kids in the back row would learn nothing new from this class

In my high school we had "General Science" for all the bored kids who flunked Introduction to Physical Science in 9th grade. Mr. Santos had a quarter-long block on aerodynamics...if the kids paid attention and did well during the academic 30 minutes of the class, they got to carve wooden duck decoys the other 30 minutes. Several of his General Science students currently earn their livings making wooden duck decoys.

Email fails me at this point, but imagine a plaintive duck call in the woods...

This is an unorganized way to demonstrate that or any physics lesson. You already lost the kids in the back row.
