Grade TwoScience Content Standards.
- The motion of objects can be observed and measured. As a
basis for understanding this concept:
- Students know the position of an object can be
described by locating it in relation to another object or
to the background.
- Students know an object's motion can be described
by recording the change in position of the object over time.
- Students know the way to change how something is
moving is by giving 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.
- Students know tools and machines are used to apply
pushes and pulls (forces) to make things move.
- Students know objects fall to the ground unless
something holds them up.
- Students know magnets can be used to make some
objects move without being touched.
- Students know sound is made by vibrating objects
and can be described by its pitch and volume.
- Plants and animals have predictable life cycles. As a basis
for understanding this concept:
- Students know that organisms reproduce offspring
of their own kind and that the offspring resemble their
parents and one another.
- Students know the sequential stages of life cycles
are different for different animals, such as butterflies,
frogs, and mice.
- Students know many characteristics of an organism
are inherited from the parents. Some characteristics are
caused or influenced by the environment.
- Students know there is variation among individuals
of one kind within a population.
- Students know light, gravity, touch, or environmental
stress can affect the germination, growth, and development
- Students know flowers and fruits are associated
with reproduction in plants.
- Earth is made of materials that have distinct properties
and provide resources for human activities. As a basis for understanding
- Students know how to compare the physical properties
of different kinds of rocks and know that rock is composed
of different combinations of minerals.
- Students know smaller rocks come from the breakage
and weathering of larger rocks.
- Students know that 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.
- Students know that fossils provide evidence about
the plants and animals that lived long ago and that scientists
learn about the past history of Earth by studying fossils.
- Students know rock, water, plants, and soil provide
many resources, including food, fuel, and building materials,
that humans use.
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.
- Make predictions based on observed patterns and not random
- Measure length, weight, temperature, and liquid volume
with appropriate tools and express those measurements in
standard metric system units.
- Compare and sort common objects according to two or more
physical attributes (e. g., color, shape, texture, size,
- Write or draw descriptions of a sequence of steps, events,
- Construct bar graphs to record data, using appropriately
- Use magnifiers or microscopes to observe and draw descriptions
of small objects or small features of objects.
- Follow oral instructions for a scientific investigation.
