    Twenty five labs to study bones, muscles, nerves, balance, reflexes, reaction time, and muscle fatigue. Many of these labs require little setup and could be used in centers or stations. The directions are written directly to the students so they can be done independently.

    Six of the labs includes a one-page reading that can be used as student reading or teacher read-aloud. Reading includes questions and answers. Each of the labs is complete in itself and builds upon concepts taught in the other labs.

    Topics & Concepts Addressed:

    ✦ Long bones vs Flat Bones

    ✦ Femur is the longest human bone

    ✦ Comparative Anatomy (Human and Chicken Bones)

    ✦ Muscles can only pull, they cannot push

    ✦ Muscles come in pairs

    ✦ Contracting muscles may either flex or extend limbs

    ✦ Muscles become fatigued when used quickly and repetitively.

    ✦ Tendons connect muscles to bones

    ✦ We can use our sense of touch to compare objects

    ✦ Some qualities of objects can be discerned by touch

    ✦ Some qualities of objects cannot be discerned by touch

    ✦ Different parts of our skin have different sensitivity.

    ✦ Sensitive fingertips allow humans to read Braille.

    ✦ Our skin is very good at assessing temperature differences.

    ✦ Reflexes are involuntary.

    ✦ We blink when objects come near our face.

    ✦ Reflexes are a nearly instantaneous response to a stimulus.

    ✦ Reaction time is a measure of how quickly you're able to respond to a signal.

    ✦ Worms' nervous systems respond to stimuli

    ✦ Every object has a center of gravity.

    ✦ Our center of gravity is located near our belly button.

    ✦ Our center of gravity must remain over our base in order to stay upright.

    ✦ If our center of mass moves outside of our base we fall over.
