Standard 1/Middle School/Benchmark 1
Benchmark Question: How are physical properties used to
describe and compare matter?
Focus Question: How can objects be described and
compared in terms of mass, volume, and density?
The teacher will set out
several different liquids, solids, containers of various sizes, and
measuring devices (balance, graduated cylinders, and metric rulers).
Students will work in small
groups to create tables for recording mass, volume, and density. They will
measure the mass, volume, and density of several items. After they have
completed their investigations, the small groups should discuss and compare
values for liquids and solids. Students also will discuss the differences
in individual measurements within the class and focus on limitations of
their personal knowledge.
(Extension: Students will research a scientist
and give a presentation describing how he or she utilized mass, volume,
and/ or density in the work he or she conducted. See “Culturally Relevant
Materials for Science Education.”
