Lab Activity
Students should observe several types and sizes of needles
Practice drawing liquid into syringes
Practice giving injections- This exercise can be done with bananas or oranges or two baggies, one inside
the other, the inner baggie should be filled with water and the outer bag should contain flour. The flour
bag represents the skin, the flour represents subcutaneous tissue and the inner baggie represents the
muscle. (chicken breats/thighs can also be used for this activity)
