Rock Candy
QUESTION:
How are rocks and minerals different?
MATERIALS:
candy (assorted samples)
PROCEDURE:
1. Lay out your samples of candy and determine which are models of a mineral
and which are models of rocks. Use the information below to help you
decide:
ROCKS are made of one or more minerals. This means that the material that
makes up an individual rock or several samples of the same kind of rock
may vary in color and texture. Rocks are heterogenous - they are
mixtures of minerals.
MINERALS all have the same chemical make-up, wherever they are found.
Different samples of the same mineral generally look the same and
have the same properties. Minerals look the same throughout, inside
and out. Minerals are homogenous - they are made up of one kind of
material.
2. Complete the data for each sample:
DATA:
