What is it that scientists do? How do scientists
go about generating new knowledge? How is this work of
generating new knowledge in science similar or different
than how a psychologist generates new knowledge?
(This is intended to be a single question with
multiple parts. Discuss it as a single question.)

Archaeologists use radioactive dating to find
the age of cave paintings, such as those from Lascaux
cave in France (Figure 1-9). Three different tests from
the cave reveal the following ages of the painting:
30,940 years + or - 610 yrs
30,790 years + or - 600 yrs
30,230 years + or - 530 yrs
Does being uncertain of a measurement by 600 (or some)
years mean the dating process is unreliable? Explain your

An experiment is performed in a science class to
investigate the effect of varying pressure upon the
volume of a gas. A sample of air is placed in a syringe.
Textbooks are placed on top of the syringe in an effort
to vary the pressure upon the gas. Every time a new
textbook is added, a new pressure and corresponding
volume are measured.
Answer the following questions about this experiment.
- Describe the purpose of this experiment in the
form of a question?
- What are the dependent and the independent
- Set up a graph which might be used to represent
the data. Label the axes with the quantities being
- Make up a sample conclusion for this experiment.
(Remember: Conclusions relate to the purpose. They
simply answer the question proposed in the

independent variable, graphing data)
