What is Science?

The goal of science is to investigate and understand the natural world, to explain events

in the natural world, and to use those explanations to make useful predictions.

Lesson 1: Identifying Scientific Questions and Problems.

In order for an idea to be considered a part of “Science”it must begin with a scientific question.

Sci – know Multi – many Stasis - stayBio – life A – not Evol - changeLogy – study of Meta – changeUni – one, single Homeo – same, alike

What is Biology?Biology is the study of LIFE!

What do Biologists do?

Some study how the environment affects plants or animals.

Some work at the molecular level studying what types of chemicals are needed by living organisms.

Some work at the cellular level studying how the cells of organisms function.

Some study populations of organisms and how they related to each other.

SCIENTIFIC QUESTION = can be studied through observation, testing, and analysis.

1. Based on observations.

(information gathered using our senses of sight, sounds, touch, etc.)

Characteristics of LIVING THINGS

Living things are made up of CELLS.

Unicellular = single celled (one cell).Multicellular = having more than one cell.Specialized = having cells that do specific jobs.

Living things REPRODUCE.

Sexual Reproduction = two gene donors.Asexual Reproduction = one gene donor.

Living things are based on a UNIVERSAL GENETIC CODE.

Living things GROW and DEVELOP.

Living things obtain and use MATERIALS and ENERGY.

Metabolism = chemical reactions which act to break down materials for life processes.

Living things RESPOND to their environment.

Stimulus (stimuli, pl.) = causes a reaction.Response = the reaction.

Living things maintain a STABLE INTERNAL ENVIRONMENT.

Homeostasis = balance of internal body.Feedback = responses to signals.

Example (chills, thirst, hunger, etc.)

Taken as a group, Living Things CHANGE OVER TIME.

Evolution = change over long periods of time.
