Keep in mind that the proposal is to eliminate optional supplemental labs, not the science classes. With that (possibly unnecessary) clarification, the race-baiting parents and educrats are asking the wrong question. They should be asking why ethnic minority students aren't taking the labs. Hands-on labs bridge the not tiny gap between textbooks and lectures and the real world. For example, in electronics, it's one thing to talk in the classroom about calculating voltages in circuits or theoretical ideal capacitors. It's something else altogether to try to measure the voltage across a 4.7M-Ohm resistor with a volt meter with a 10M-Ohm internal resistance or to use in a circuit a capacitor with a lousy temperature coefficient or an undesirably high internal series resistance.
