North Carolina State Standards
- Science Competency Goals, Grade 8
The Middle Grades chapter of North Carolina's Science
Standard Course of Study describes Competency Goals,
the first two of which apply to all middle-school grades,
involving scientific inquiry and technological design,
and are described in DITC's
Shared Competency Goals page. "Designing technological
solutions and pondering benefits and risks should be
an integral part of the middle-school science experience."
In addition to Competency Goals 1-2, Goal 4 has a strong
link to a design-related activity developed at Harvard.
Challenges In Physical Science curriculum offers
one of the few design challenges related to chemistry.
Baking Soda asks students to find a replacement
for yeast in making bread rise. They are given two ingredients
-- vinegar and baking soda -- and asked to find the
ratio that will help bread rise highest with the least
amount of residue. Although this design activity has
a single correct solution (ideal ratio of vinegar to
baking soda), students can nevertheless learn about
design while discovering some basic chemistry lessons.
Competency Goal 4: Chemistry
4.01 Understand that both naturally
occurring and synthetic substances are chemicals.
4.04 Describe the suitability of materials
for use in technological design.
4.10 Describe risks and benefits of
chemicals including medicine, food preservatives, crop
yield and sanitation.
4.05 Identify substances based on characteristic
4.06 Describe and measure quantities
to chemical/physical changes within a system.
4.07 Identify evidence supporting the
law of conservation of matter.
Competency Goal 5: Evolution
5.02 Correlate evolutionary theories
and processes (biological, geological, technological).
Competency Goal 6: Cell Theory
6.02 Analyze structures, functions
and processes within animal cells for -- capture and
release of energy; feedback information; and disposal
