CH 1 Investigating Human Biology

The scientific study of humans and their interaction with their environment

> Science is a process of inquiry- a way of finding out about human beings and their living and non-living organisms Science is a body of knowledge- knowledge gained by systematic observation and testing of ideas

• Literature review • Observation • Classification • Experimentation

A review of books, scientific journals and the internet to see what information has already been collected by others.

Information is gathered by using the sense or instruments that enhance the senses. • Patient observation produces data that must be carefully analysed • Scientists look for patterns and trends in the data and draw conclusions • Observation might not always conclude a scientific investigation

• Propose a hypothesis, a possible explanation or solution to a problem, then design experiments to test it • An experiment must be designed so that the evidence either supports or disproves the hypothesis. This is done by testing one variable at a time

The process of using the senses to acquire information

The grouping of organisms based on the similarity of their characteristics, the placement of organisms into groups

Any factor that may change during an experiment

A procedure carried out to give a comparison in an experiment

Structure of the body

Relationships between biological, cultural, geographical and historical aspects of humans to mean the same as human biology

Material evidence of the past such as tools, weapons and art rather than written recrords

Chemistry of all living things

cells

Statistical study of populations

Development from fertilisation to birth

How characteristics are passed from generation to generation

Macromolecules of the cell

Food requirements of humans

fossils

Functioning of living things

The past, before the time of written records

Non-human members of the order of primates
