TEAS Science Q & A [2025]
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
,Page 2 of 56
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.
, Page 4 of 56
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
