Scientific Investigation
The student demonstrates scientific competence by completing projects
drawn from the following kinds of investigations, including at least one
full investigation each year and, over the course of middle school, investigations
that integrate several aspects of Science Standards 1 to 7 and represent
all four of the kinds of investigation:
a |
Controlled experiment. |
b |
Fieldwork. |
c |
Design. |
d |
Secondary research, such as use of others’ data. |
A single project may draw on more than one type of investigation.
A full investigation includes:
- Questions that can be studied using the resources available.
- Procedures that are safe, humane, and ethical; and that respect privacy
and property rights.
- Data that have been collected and recorded (see also Science Standard
6) in ways that others can verify, and analyzed using skills expected
at this grade level (see also Mathematics Standard 4).
- Data and results that have been represented (see also Science Standard
7) in ways that fit the context.
- Recommendations, decisions, and conclusions based on evidence.
- Acknowledgment of references and contributions of others.
- Results that are communicated appropriately to audiences.
- Reflection and defense of conclusions and recommendations from other
sources and peer review.
Examples of projects through which students might demonstrate competence
in scientific investigation include:
- Analyze de-icers for relative effectiveness, cost, and environmental
impact. 8a, 1a, 3d, 4d
- Study different methods for cooking chicken considering health and
aesthetics. 8a, 8c, 4c
- Conduct a field study of monument degradation over time at a local
cemetery. 8b, 1a, 3a
- Adopt a stream and use that location to study habitat and water quality
over time. 8b, 2d, 3a
- Design a protective container for an uncooked egg using the concepts
of force, motion, gravity, and acceleration and test the design by dropping
the container (egg enclosed) from a one-story building.
8c, 1a, 1b
- Research local climate changes over the last century.
8d, 3a
Standard 1 Analysis, Inquiry, and Design
Scientific Inquiry
- The central purpose of scientific inquiry is to develop explanations
of natural phenomena in a continuing, creative process.
- Beyond the use of reasoning and consensus, scientific inquiry involves
the testing of proposed explanations involving the use of conventional
techniques and procedures and usually requiring considerable ingenuity.
p. 4
- The observations made while testing explanations, when analyzed using
conventional and invented methods, provide new insights into phenomena.
p. 5
Engineering Design
- Engineering design is an iterative process involving modeling and
optimization finding the best solution within given constraints which
is used to develop technological solutions to problems within given
constraints. p. 5
| Standard A Science
as Inquiry
Design and conduct a scientific investigation. Students should
develop general abilities, such as systematic observation, making
accurate measurements, and identifying and controlling variables.
They should also develop the ability to clarify their ideas that
are influencing and guiding inquiry, and to understand how those
ideas compare with current scientific knowledge. Students learn
to formulate questions, design investigations, execute investigations,
interpret data, use evidence to generate explanations, propose alternative
explanations, and critique explanations and procedures. p. 145
Standard E Science and Technology
Identify a problem or design an opportunity.
Propose designs and choose between alternative solutions.
Implement a proposed solution.
Evaluate the solution and its consequences.
Communicate the problem, process, and solution. p. 192 |
Chapter 1 The Nature of
Science
1B Scientific Inquiry
Scientists differ greatly in what phenomena they study and
how they go about their work. Although there is no fixed set of
steps that all scientists follow, scientific investigations usually
involve the collection of relevant evidence, the use of logical
reasoning, and the application of imagination in devising hypotheses
and explanations to make sense of the collected evidence. p. 12
Chapter 3 The Nature of Technology
3B Design and Systems
Design usually requires taking constraints into account. Some constraints,
such as gravity or the properties of materials to be used, are unavoidable.
Other constraints, including economic, political, social, ethical,
and aesthetic ones, limit choices. p. 51
