CA SCIENCE CONTENT STANDARDS
|
|
1. |
THE FIRST STRAW |
|
Students learn the need for standard units
of linear measurement. They measure
objects with nonstandard units (straws),
and then use a meter tape to measure
objects in meters and centimeters. Later
they apply linear metric measures to
study motion. |
|
I&E4b Measure length, weight, temperature,
and liquid volume in metric units.
I&E4g Follow oral instructions for a scientific
investigation.

2. |
BALANCE |
|
Students explore numerous ways
to balance two-dimensional shapes
made out of tagboard by positioning
counterweights (clothespins) in
strategic locations. They make mobiles
to apply their understanding of a stable
position. |
PS1a The position of an object can be
described in relation to another
object or to the background.
|
I&E4a Make predictions based on observed
patterns.
I&E4d Write/draw descriptions of a sequence.
I&E4g Follow oral instructions for a scientific
investigation.
|
|
3. |
SPINNERS |
|
Students explore the variables that
influence the spinning of a top, a
zoomer, and twirlers (flying spinners).
They explore the forces (pushes and
pulls) that make tops and zoomers
move. They observe the force of gravity
causing objects to fall (twirlers). |
PS1b An object’s motion can be described
by recording its change in position
over time.
PS1c The way to change how something
is moving is by giving it a push or a
pull.
PS1e Objects fall to the ground unless
something holds them up.
|
I&E4d Write/draw descriptions of a sequence.
I&E4g Follow oral instructions for a scientific
investigation.
|
|
4. |
ROLLERS |
|
Students investigate rolling objects—wheels, cups, and spheres—and describe
change in position over time. They gain
more experience with gravity causing
objects to fall to the ground. Students
use flexible marble runways to observe
an object’s change of position. |
PS1b An object’s motion can be described
by recording its change in position
over time.
PS1c The way to change how something
is moving is by giving it a push or a
pull.
PS1e Objects fall to the ground unless
something holds them up.
|
I&E4a Make predictions based on observed
patterns.
I&E4b Measure length, weight, temperature,
and liquid volume in metric units.
|
|
5. |
BACK AND FORTH |
|
Students explore the production of sound with a door fiddle, tuning forks, xylophone, kalimba, and a long gong. Through these explorations, students look for vibrations at the sound source and explore how to change pitch and volume of sound. |
PS1c The way to change how something is moving is by giving it a push or a pull.
PS1g Sound is made by vibrating objects and has pitch and volume.
|
I&E4a Make predictions based on observed patterns.
I&E4b Measure length, weight, temperature, and liquid volume in metric units.
I&E4d Write/draw descriptions of a sequence.
I&E4g Follow oral instructions for a scientific investigation.

MAGNETS AND TOOLS |
|
Students work with magnets and find
that two magnets will either attract or
repel one another, depending on their
orientation (force at a distance). They
read about and view a video on how
tools and machines make things move. |
PS1d Tools and machines are used to
apply forces to make things move.
PS1f Magnets make some objects move
without being touched.
|
I&E4a Make predictions based on observed
patterns.
