Period 8 , and for those of you who want to get a jump on tomorrow's class work, here are the p. A-24 Analysis Questions (Answer questions 1-5 only):
Vocab Quiz coming up on Friday!!! Here are the vocab words that you'll be quizzed on:
*Control - the part of an experiment that doesn't change. Ex: in touch test, we did not change the part of the body or the device being used.
Interneuron - connect the sensory and motor neurons; found in brain or spinal cord.
*Levels of Organization:cells -> Tissues -> organs -> organ systems -> organisms
Motor neuron - take message from brain to muscles that actually move, whether
voluntary or involuntary.
Nerves - found throughout your body, from the tips of your toes to the top of your head
Neuron - a nerve cell that transmits messages.
Reproducible - able to be recreated and repeated.
*Sample size - the amount of data gathered for an experiment. ex :in touch test, you each did 30 trials.
Sensitivity - how much an organism or part will respond to stimulation.
Sensory neuron - nerves that gather information from the world around us through senses (e.g., sight, hearing, touch, etc.).
Nervous system - includes and connects brain, spinal cord, and nerves. (You should already have this one from class, but if you don't you should copy it into your science notebook).
Tissue - A group of similar cells and cellular material that perform a particular function.
Touch receptors - nerve endings that detect pressure on your skin and send a message to your brain.
