TO PERFECTION| STUDY WITH CONFIDENCE!
Investigations are conducted to - Answer: Identify potential problems and to create
solutions to those problems before they actually occur
Hypothesis - Answer: An explanation formulated to answer the questions being
investigated; A statement that can be tested
Steps of Forming a Hypothesis - Answer: 1. Identify the problem-Observe and determine
the problem to be investigated
2. Ask questions-Ask questions and attempt to formulate a solution to the problem
3. Formulate a Hypothesis-Formulate explanations to answer the questions. This involves
making predictions that follow from the initial statement of the problem. Is not subject to
interpretation.
If no reasonable test can be designed.. - Answer: it becomes necessary to reformulate the
hypothesis. It is of little value to quantitatively pursue the validity of a statement without
any ability to measure an outcome.
Scientific Method - Answer: 1. Problem identification
2. Question asking
3. Hypothesis development
4. Data collection and experimentation
5. Analysis
6. Conclusion

,Data Collection - Answer: Collect data throughout the scientific process to test the
hypotheses or predictions in a controlled environment.
4 Main Steps of Data Collection - Answer: 1. Observation
2. Measurement
3. Samples
4. Organization
Observation - Answer: Scientists use the 5 senses to learn as much as possible during data
collection.
Direct-such as listening to a bird call
Indirect-such as observing qualities of planets
Measurement - Answer: Allows for collection of quantitative data
Samples - Answer: Data typically cannot be collected from every member of a population.
Collect information from a representative sample of the population. Obtain data from a
subset of the population that looks like the population, but is small and more manageable.
Organization - Answer: Data should be organized. May involve placing informatin in tables
and/or charts.
Experimentation - Answer: Involves comparing a control group and an experimental group.
Both groups are compared to understand what effect the variable has on the experimental
group.
Analysis - Answer: Must analyze data collected during experimentation. The researchers
must determine if the data is reliable (consistent with past results) and whether or not it
supports the hypothesis.

,Conclusion - Answer: Scientists produce models to represent the explanations supported
by the data.
Inference - Answer: A way of drawing conclusions without direct observatioin
Theory - Answer: Broad statement of what is thought to be true; A theory that is thought to
be true may be proven incorrect when technology enables better data collection
Mathematics in Science Research - Answer: Data is recorded in numerical form.
Data are then related to one another through the relationships established by graphs and
empirical formulas.
No modern conveniences could exist without math because the creation of all technology
is ultimately mathematical.
If mathematics was not used.. - Answer: the best scientific descriptions would be purely
qualitative in nature.
Quantitative Investigations - Answer: Uses numerical information (or data)
Data management - Answer: through the use of software programs improves the efficiency
of an investigation
Scientific explanations (or models) - Answer: Direct results of the evidence that currently
supports them
As improvements are made, collection of new data often leads to more refined alternative
explanations - Answer: Measuring and observational devices have been developed so that
smaller increments of time and length have become accessible

, Deductive reasoning - Answer: A method whereby conclusions follow from general
principles; Leads to a specific conclusion; General to Specific
Inductive reasoning - Answer: A method of arriving at general principles from specific facts;
Specific to General
Anatomy - Answer: Study of the structure of organs and body systems
Physiology - Answer: Study of the function of the organs and body systems
Atoms - Answer: Smallest parts of elements that still retain all the original properties of the
element
Molecules - Answer: Atoms combine to form this
Cells - Answer: Specific molecules combine to form this
Is the basic unit of all life
Tissues - Answer: Cells combine in terms of function and type to form this
Organ Level - Answer: Two or more tissue types work together to perform a specific
function; Possible to perform extremely complex functions
Organ System - Answer: When organs work together to perform a task
How many organ systems are there in the human body? - Answer: 11 organ systems
