Physical Sciences
1. Materials come in different forms (states) including solids, liquids,
and gases.
As a basis for understanding this concept, students know:
a. solids, liquids, and gases have different properties.
b. the properties of substances can change when the
substances are mixed, cooled, or heated.
Life Sciences
2. Plants and animals meet their needs in different ways.
As a basis
for understanding this concept, students know:
a. different plants and animals inhabit different kinds of
environments and have external features that help
them thrive in different kinds of places.
b. plants and animals both need water; animals need
food, and plants need light.
c. animals eat plants or other animals for food and may
also use plants or even other animals for shelter and
nesting.
d. how to infer what animals eat from the shapes of
their teeth (e.g., sharp teeth: eats meat; flat teeth: eats
plants).
e. roots are associated with the intake of water and soil
nutrients, green leaves with making food from sunlight.
Earth Sciences
3. Weather can be observed, measured and described.
As a basis for
understanding this concept, students know:
a. how to use simple tools (e.g., thermometer, wind
vane) to measure weather conditions and record
changes from day to day and over the seasons.
b. the weather changes from day to day, but trends in
temperature or of rain (or snow) tend to be predictable
during a season.
c. the sun warms the land, air, and
water.
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. draw pictures that portray some features of the thing
being described.
b. record observations and data with pictures,
numbers, and/or written statements.
c. record observations on a bar graph.
d. describe the relative position of objects using two
references (e.g., above and next to, below and left of).
e. make new observations when discrepancies exist
between two descriptions of the same object or
phenomena.
