A still life is a painting that depicts inanimate things like fruit, flowers, plants, jewelry, etc. It is made to look as realistic as possible. When you examine a still life, I assume that means you would point out what you notice about it and/or what techniques the artist used to make it look true to life (shadows, lighting, texture, etc.).
A still life is a painting or drawing of an arrangement of objects. To draw a still life set up some objects in front of you (EXAMPLE: 2 apples and a pineapple OR a vase of flowers) and draw what you see. A color scheme is the choice of colors used in design. The 'choice' of color schemes just means that you can choose whatever color group/range you want to use to color in the still life you just drew.
