Biology is The Study of Life “Bios” - Life “Logos” - Study What is Biology? Section 1.1

The interactions of Life The interactions with the Environment They study problems and propose solutions (i.e. medical treatment, disease prevention etc) What do Biologists Study? Section 1.1

All Living Things are Organisms What is an Organism? Section 1.1

Organization Reproduction Growth and Development Ability to Adjust to Environment Living Things Adapt and Evolve Characteristics of Living Things Section 1.1

Am I an Organism? Section 1.1

All living things are composed of One or More cells Each cell contains DNA All parts function together in an orderly living system Organization Section 1.1

The production of Offspring Same Species They can Interbreed They produce fertile offspring What is Reproduction? Section 1.1

Growth: Gradual increase in size over time. Results in more living material and forms new structures Development: All the changes that take place during the life of an organism Growth and Development Section 1.1

Living Things are able to Adjust to their environment Environment: The surroundings of the organism - e.g. air, weather, temperature, other organisms and many other factors Adjusting to the Environment Section 1.1

Stimulus: Any condition that requires a response Response: Reaction to a stimulus Homeostasis: Maintaining conditions suitable for survival (takes energy) Adjusting to the Environment Section 1.1

Adaptation: Any structure, behavior or internal process that enables an organism to respond to stimuli better and better survive in an environment Evolution: gradual accumulation of adaptations over time Change Over Time Living Things Adapt and Evolve Section 1.1

Section 1.2 The Scientific Method

Section 1.2 Examples of The Scientific Method Examples of The Scientific Method

Experiments that involve 2 Groups: Control Group - Group that represent the standard conditions Experimental Group - The test Group that receives Experimental treatment Controlled Experiments Section 1.2

The Frog Egg Experiment

Independent Variable The condition in an experiment that is changed (Only One) Dependent Variable The condition in an experiment that changes because of the change in the independent variable Variables in Experimental Group Section 1.2

The Frog Egg Experiment Independent Variable: UV Light

Ethics: moral principles and values held by humans Society plays a vital role in determining what is ethical or not ethical when it comes to science Science and Society Section 1.3

Quantitative dealing with numerical data (counts/measurements) Uses the International system of measurement (SI) meter gram liter second Celsius 2 Kinds of Research Section 1.3 (length) (weight) (volume) (time) (temperature)

Descriptive: Uses written descriptions of what a scientist observes. E.g. Animal behavior 2 Kinds of Research Section 1.3

Science doesn’t answer all questions E.g. Luck, Ugly vs. Beautiful, Good vs. evil Must be able to devise a controlled experiment The Realm of Science Section 1.3

Pure Science is mainly for the purpose of getting knowledge e.g. Studying the human eye/vision Applied Science has immediate application for daily living Designing glasses/lenses Pure Science vs. Applied Science Section 1.3

What is Technology? The Application of scientific research to society’s needs and problems Technology Section 1.3

What are the steps of the Scientific Method? What are the two groups in a controlled experiment? What are the two types of Research? Which is done mainly for the purpose of gaining knowledge? Pure Science or Applied Science Recap Quiz: Sections 1.2 and 1.3
