FOSS AND CALIFORNIA STANDARDS
The Pebbles, Sand, and Silt Module supports the following
Investigation and Experimentation Content Standards for grade 2.*
INVESTIGATION AND EXPERIMENTATION
I&E4. 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. Students will
I&E4a. make predictions based on observed patterns and not
random guessing.
I&E4b. measure length, weight, temperature, and liquid volume
with appropriate tools and express those measurements
in standard metric system units.
I&E4c. compare and sort common objects according to two
or more physical attributes (e.g., color, shape, texture,
size, weight).
I&E4d. write or draw descriptions of a sequence of steps,
events, and observations.
I&E4e. construct bar graphs to record data, using appropriately
labeled axes.
I&E4f. use magnifiers or microscopes to observe and draw
descriptions of small objects or small features of objects.
I&E4g. follow oral instructions for a scientific investigation.
