Buy 5th graders chickens.
Not just any chickens- fertilized eggs and an incubator.
It has become painfully apparent to me that most urban pro-choice Americans can't tell the difference between a unfertilized egg and a fertilized egg. That's ok, lots of experts can't either. But to compare the human embryo to an unfertilized egg just shows an incredible ignorance of how sex works.
Thus the lesson. Don't make it to overt- but do call it "The Miracle of Life, a Scientific Experiment". In the brochures and reading material, explain fertilization on a 5th grade level. Include a description of what the mother hen does naturally after the eggs have been fertilized. Watch the robot incubator do the same.
This $200 incubator could help 30 students learn enough science to resist the lies of the pro-choice movement
And here's an even cheaper one, that comes with three eggs.
