Physical Sciences
1. The motion of objects can be observed and measured.
As a basis
for understanding this concept, students know:
a. the position of an object can be described by
locating it relative to another object or the background.
b. an object's motion can be described by recording
the change in its position over time.
c. the way to change how something is moving is to
give it a push or a pull. The size of the change is
related to the strength, or the amount of "force," of the
push or pull.
d. tools and machines are used to apply pushes and
pulls (forces) to make things move.
e. objects near the Earth fall to the ground unless
something holds them up.
f. magnets can be used to make some objects move
without being touched.
g. sound is made by vibrating objects and can be
described by its pitch and volume.
Life Sciences
2. Plants and animals have predictable life cycles.
As a basis for
understanding this concept, students know:
a. organisms reproduce offspring of their own kind. The
offspring resemble their parents and each other.
b. the sequential stages of life cycles are different for
different animals, for example butterflies, frogs, and
mice.
c. many characteristics of an organism are inherited
from the parents. Some characteristics are caused by,
or influenced by, the environment.
d. there is variation among individuals of
one kind within a population.
e. the germination, growth, and development of plants
can be affected by light, gravity, touch, or
environmental stress.
f. in plants flowers and fruits are
associated with reproduction.
Earth Sciences
3. Earth is made of materials that have distinct properties and provide
resources for human activities.
As the basis for understanding this
concept, students know:
a. how to compare the physical properties of different
kinds of rocks and that rock is composed of different
combinations of minerals.
b. smaller rocks come from the breakage and
weathering of larger rocks.
c. soil is made partly from weathered rock and partly
from organic materials, and that soils differ in their
color, texture, capacity to retain water, and ability to
support the growth of many kinds of plants.
d. fossils provide evidence about the plants and
animals that lived long ago, and scientists learn about
the past history of Earth by studying fossils.
e. rock, water, plants and soil provide many resources
including food, fuel, and building materials that
humans use.
Investigation and Experimentation
4. Scientific progress is made by asking meaningful questions and
conducting careful investigations.
As a basis for understanding this
concept, and to address the content the other three strands, students
should develop their own questions and perform investigations.
Students will:
a. make predictions based on patterns of observation
rather than random guessing.
b. measure length, weight, temperature, and liquid
volume with appropriate tools and express
measurements in standard and non-standard units.
c. compare and sort common objects based on two or
more physical attributes (including color, shape,
texture, size, weight).
d. write or draw descriptions of a sequence of steps,
events, and observations.
e. construct bar graphs to record data
using appropriately labeled axes.
f. write or draw descriptions of a sequence of steps,
events and observations, and include the use of
magnifiers or microscopes to extend senses.
g. follow verbal instructions for a
scientific investigation.
