biology

• Biology

  study of life
• Biology

  study the origins and history of life and once-living

  things
• Biology

  study the structures of living things
• Biology

  study how living things function
• Biology

  study how living things interact with one another
• Biology

  is relevant to our everyday experience
• Science

  is a body of knowledge based on the study of nature.
• Scientific Inquiry

  is both a creative process and a process rooted in unbiased observations and experimentation.
• Nature

  essential characteristic of science
• Theory

  is an explanation of a natural phenomenon supported by many observations and experiments over time.
• Peer Review

  is a process by which the procedures used during an experiment and the results are evaluated by other scientists who are in the same field or who are conducting similar research.
• Before it is made public, science-based information is reviewed by scientists’ peers
• Science-based information makes claims based on a large amount of data and observations obtained from unbiased investigations and carefully controlled experimentation.
• The metric system uses units with divisions that are powers of ten.
• Ethical Issues

  must be addressed by the society based on the values it holds important.
• Scientific Method

  it is the backbone of every science experiment. It is a methodical framework to solve problems and determine answers in a step-by-step logical format.
• Scientific Method

  It is a process that is used to find answers to questions about the world around us.
• Ask a question.

  Research the topic.

  Form a hypothesis.

  Test the Hypothesis.

  Gather Data.

  Analyze Results.

  Draw Conclusions.

  Communicate Results.
• Reproduction is necessary on both a cellular and organismal level.
• For a population to survive, some individuals within that population must reproduce.
• Asexual

  One individual gives rise to two or more offspring that are similar to the parent
• Sexual

  Typically, the two parents contribute a gamete (sperm or egg). Gametes fuse to produce offspring, which has a combination of the traits of both parents.
• Development

  is often described as the processes that an organism goes through as it grows and matures
• Photosynthesis

  is a process where light energy can be captured and converted into chemical energy.
• Organisms that are capable of making their own chemical energy are referred to as autotrophs.
• Others must obtain their chemical energy by consuming other organisms. These individuals are referred to as heterotrophs.
• Scientific Method

  is a series of defined steps that include experiments and careful observations.
• TRUE

  True or False

  If a hypothesis is not supported by data, a new hypothesis ca be proposed
• Step 1: Ask a Question
• Step 2: Research the topic
• Step 3: Form a Hypothesis
• Step 4: Test the Hypothesis
• Controlled Experiment

  An experiment that tests only one factor at a time by using a comparison of a control group and an experimental group.
• Control Group

  the group that the scientist changes nothing in. This is used for comparison
• Experimental Group

  The group that the scientist has changed something. It is the variable in the experiment where you want to see how this condition affects something.
• Variable is something that can change, either naturally or on purpose.
• Independent Variable

  The factor that the scientist has changed in order to test the hypothesis (on purpose). It is the cause
• Dependent Variable

  The result of what the scientist changed. It is the effect of what happened in the experiment.
• Controlled Variable

  A variable that is not changed. Also called constants. Allow for a “fair test”
• Step 5: Gather Data
