1. |
FIRST ROCKS |
|
• Rocks have a variety of properties
including color, hardness, shape,
texture, and size.
• Rocks can be sorted by their
properties.
• Rocks are all around us.
• Rocks are the solid material of the
earth.
• Rocks are made of minerals. |
• FOSS Science Resources: Pebbles,
Sand, and Silt, “Exploring Rocks”
and “Colorful Rocks”
• Science Notebook: Students
draw and write their
observations about rocks.
|
Teacher Observation/Notebook Sheet
• Observes and records properties
of rocks.
• Compares and sorts rocks.
|
|
|
2. |
RIVER ROCKS |
|
• Rocks can be categorized by size.
• Screens and water can be used to
sort the sizes of earth materials.
• Five sizes of rocks, from smallest to
largest, are clay, silt, sand, gravel,
and pebbles. |
• FOSS Science Resources: Pebbles,
Sand, and Silt, “The Story of Sand”
• Science Notebook: Students draw
and write about the results of
sorting river rock mixture, using
screens and water.
|
Teacher Observation/Notebook Sheet
• Observes and seriates rocks based
on the property of size and uses
appropriate vocabulary.
• Uses a balance to weigh rocks and
record in grams.
• Describes the appropriate
sequence of steps to weigh an
object.
• Observes and compares results of
earth materials in water.
|
|
3. |
USING ROCKS |
|
• Earth materials are natural
resources.
• The properties of different earth
materials make each suitable for
specific uses.
• Earth materials can be used in a
variety of constructions. |
• FOSS Science Resources: Pebbles,
Sand, and Silt, “Rocks Move” and “Making Things with Rocks”
• Science Notebook: Students write
about the uses of earth materials.
|
Notebook Sheet
• Observes uses for earth materials
and describes these uses.
|
|
4. |
SOIL EXPLORATIONS |
|
• Soil is a mixture of earth materials.
• Soils vary from place to place.
• Soils have properties of color and
texture.
• Soils differ in their abilities to
support plants and retain water.
• Soils can be composed of humus and
different amounts and sizes of rocks.
• Fossils are the remains of plants and
animals that lived a long time ago. |
• FOSS Science Resources: Pebbles,
Sand, and Silt, “What Is in Soil?”
”Testing Soil,” and “Fossils”
• Science Notebook: Students
describe soil samples, using
drawings and words. Students
write a sequence of steps in an
investigation. |
Teacher Observation/Notebook Sheet
• Accurately observes and records
observations.
• Applies methods and tools to
study properties of soil.
• Writes the sequence of steps in an
investigation.
• Uses measurement tools.
