National Standard / State Standard.
A. NSES Content Standard A: as a result of activities in grades K-4,
all students develop understanding about scientific inquiry.
B. NSES Content Standard B: as a result of the activities in grades
K-4, all students should develop an understanding of properties of
objects and materials.
C. GPS Content Standard S3E1. Students will investigate the
physical attributes of rocks and soils.
Element a. Explain the difference between a rock and a mineral.
Element b. Recognize the physical attributes of rocks and minerals
using observation (shape, color, texture), measurement, and simple
tests (hardness).
D. GPS Habit of Mind Standard S3CS1. Students will be aware of
the importance of curiosity, honesty, openness, and skepticism in
science and will exhibit these traits in their own efforts to
understand how the world works.
b. Offer reasons for findings and consider reasons suggested by others.

Minerals
Rocks and Minerals Video

Minerals are the “building blocks” of Earth,
because almost everything people use is made up
of some kind of mineral.

All rocks are made of minerals, but a rock must
have two or more minerals to be called a “rock”.
Rocks

Rocks are the materials that
make up all mountains, cliffs,
sand and soil on Earth.

Rocks are made up of many
kinds of Minerals. (At least
two or more.)

There are three kinds of
rocks: Igneous, Sedimentary,
and Metamorphic.
“Testing!”


A Geologist is a special kind of
scientist who studies minerals.
Geologists use several tests to identify kinds
of minerals:
- Hardness: How easily does the mineral get
scratched?
- Weight: How heavy is the mineral?
- Luster: How shiny is the mineral?
- Clear: How well can you see through the
mineral?
- Color: What color is the mineral?
Groups!
