1. |
SOLIDS
|
 |
Students
explore solid objects, such as pieces of wood, plastic, and
metal. They observe, describe, and sort the objects according
to their properties. They construct towers (and other structures),
using the properties inherent in the materials to accomplish
the task. |
•
Solids are one state of matter.
• Solid materials have properties that separate them from
other states of matter.
• Solids can be sorted by their properties.
• Solid materials have distinct uses based on their properties. |
•
Observe several kinds of solid materials.
• Compare properties of solid materials.
• Sort solids in different ways. |
|

LIQUIDS |
 |
Students
investigate liquids in a variety of settings to become familiar
with their properties. A number of games are used to rehearse
precise liquids vocabulary. Students also use representational
materials to enhance their understanding of the unique behaviors
of liquids. |
•
Liquids are one state of matter.
• Liquids have many properties.
• Liquids pour and flow.
• Liquids take the shape of their container.
• The surface of liquid is level with respect to the ground. |
•
Observe and describe properties of different liquids in bottles.
• Compare the appearance and behavior of different liquids
in containers. |
|

BITS
AND PIECES |
 |
Students
work with beans, rice, and cornmeal to find out how solids behave
when the pieces are small. They shake, rattle, and roll the
materials in bottles, pour them from container to container,
and separate them using screens. |
•
Solid materials come in all sizes and shapes.
• Particles of solid materials can pour like liquids,
but maintain their shape.
• Solid materials can support denser materials on their
surface.
• Mixtures of solid particles can be separated with a
screen. |
•
Observe properties of solid particles in different containers.
• Separate a mixture of solids by using screens.
• Observe and describe the properties of solid particles
in closed bottles.
• Use representational materials to separate particles
based on size. |
|

SOLIDS
AND LIQUIDS WITH WATER |
 |
Students
investigate interactions between solids and water and liquids
and water. They observe, describe, record, and organize the
results. In the culminating activity students test toothpaste
to determine if it is a solid or a liquid. |
•
Some solids change when mixed with water; others do not.
• Some solids dissolve in water; evaporation leaves the
solid behind.
• Some liquids mix with water; other liquids form a layer
above or below water. |
•
Observe and describe what happens when solids and water are
mixed.
• Observe and describe what happens when liquids and water
are mixed.
• Organize observations of mixtures. |
