Who is coming up with this ****!
They should be taken out and beaten with a fan belt. I volunteer in our local elementary school and I see this all the time.
Last week it was genetics in 5th grade- similar unit to the genetics in my high school biology, but covered in half the time. Genes, alleles, dominant and recessive traits, punnett squares, great stuff but covered in one week with kids who had no context, no foundation for it.
And the teachers just totally sweating it cause it's all covered on the end of grade tests, which is apparently a big part of their evaluation.
It's really an awful thing.
