Grade OneScience Content Standards.
- Materials come in different forms (states), including solids,
liquids, and gases. As a basis for understanding this concept:
- Students know solids, liquids, and gases have
- Students know the properties of substances can
change when the substances are mixed, cooled, or heated.
- Plants and animals meet their needs in different ways. As
a basis for understanding this concept:
- Students know different plants and animals inhabit
different kinds of environments and have external features
that help them thrive in different kinds of places.
- Students know both plants and animals need water,
animals need food, and plants need light.
- Students know animals eat plants or other animals
for food and may also use plants or even other animals for
shelter and nesting.
- Students know how to infer what animals eat from
the shapes of their teeth (e.g., sharp teeth: eats meat;
flat teeth: eats plants).
- Students know roots are associated with the intake
of water and soil nutrients and green leaves are associated
with making food from sunlight.
- Weather can be observed, measured, and described. As a basis
for understanding this concept:
- Students know how to use simple tools (e.g.,
thermometer, wind vane) to measure weather conditions and
record changes from day to day and across the seasons.
- Students know that the weather changes from day
to day but that trends in temperature or of rain (or snow)
tend to be predictable during a season.
- Students know the sun warms the land, air, and
Investigation and Experimentation
- Scientific progress is made by asking meaningful questions
and conducting careful investigations. As a basis for understanding
this concept and addressing the content in the other three strands,
students should develop their own questions and perform investigations.
- Draw pictures that portray some features of the thing
- Record observations and data with pictures, numbers,
or written statements.
- Record observations on a bar graph.
- Describe the relative
position of objects by using two references (e.g., above
and next to, below and left of).
- Make new observations when discrepancies exist between
two descriptions of the same object or phenomenon.
