Tell your neighbor where it was. Today we are going to learn the three different kinds of rocks igneous, sedimentary, metamorphic - and how to tell the differences in each. All rocks should be labeled. Pictures for a bulletin board should be noticed. Safety precautions should be taken, such as droppers for vinegar put off-limits for the students.
Limestone is a type of sedimentary rock.
It consists of plant and animal remains. Tell the students that chalk is a type of limestone. Some buildings are also built from limestone. Sandstones are another type of sedimentary rocks used in buildings. Fossils are found in some types of sedimentary rocks.
