Experiment with Childrens virtual neuron to see what conditions are needed to make it fire and what happens when you connect it to other neurons. This interactive feature also provides step-through animations illustrating how electrical currents move through the cell and how it passes signals on to other neurons.
After 27 years as a science teacher and 9 years as the Texas Education Agency’s director of science, Christine Castillo Comer said she did not think she had to remain “neutral” about teaching the theory of evolution.
“It’s not just a good idea; it’s the law,” said Ms. Comer, citing the state’s science curriculum.
But now Ms. Comer, 56, of Austin, is out of a job, after forwarding an e-mail message on a talk about evolution and creationism — “a subject on which the agency must remain neutral,” according to a dismissal letter last month that accused her of various instances of “misconduct and insubordination” and of siding against creationism and the doctrine that life is the product of “intelligent design.”
I honestly can’t believe people are still having this so-called “debate.” On the one hand, you have a theory based on sound science. On the other, you have an unprovable philosophy based on reasoning and faith, having nothing to do with science. One of those belongs in a science classroom, and one doesn’t. No one should have to remain impartial about that.
