| A | B |
|---|
| Evidence | Any type of data that is gained from a scientific investigation |
| Hypothesis | An educated guess based on previous scientific knowledge |
| Observation | Anything that can be detected using human senses such as sight sound touch taste. An observation can also be made using a instrument that takes measurements |
| Science | A way of gaining knowledge that starts with a question and then tries to answer that question using evidence and logic |
| Scientific Investigation | A plan for asking questions and testing for possible answers |
| Scientific Law | What will always happen under certain conditions in nature |
| Scientific Method | A basic method for gaining knowledge in the scientific community |
| The Scientific Method Step 1 | Ask a Questions/ Make an Observations |
| The Scientific Method Step 2 | Do Background Research |
| The Scientific Method Step 3 | Construct a Hypothesis |
| The Scientific Method Step 4 | Test with an Experiment |
| The Scientific Method Step 5 | Analyze Results/ Draw a Conclusion |
| The Scientific Method Step 6 | Decide if your hypothesis is true or false. If it is true report results. If it is false come up with a new question or idea based on the information. |
| The Scientific Method Step 7 | Report Results |
| The Goal of Science | To understand the natural world |
| Independent Variable | The variable that affects the dependent variable |
| Dependent Variable | The affected variable in an experiment. Typically it is the one that is measured. |
| Experiment | A type of scientific investigation that is performed under controlled conditions. |
| Model | A representation of something that is occurring in the real world |
| Control Group | A group during an experiment that remains untouched or unaltered. This is often compared to the experimental group. |
| Scientific Theory | An explanation for something in the natural world that is widely accepted as true. |
| Experimental Group | The Group that is being tested in the experiment |
| Types of Scientific Investigations | Natural Study, Model and Experiment |
| Natural Study | A study done in nature but it is hard because you cant but controls on natural factors such as temperature, weather etc... |
| Model | A small representation of something that happens in nature. |
| Biology | The study of life |
| Reproduction | The process by which living things give rise to offspring |
| Homeostasis | Maintaining a stable internal environment |
| Cell | The smallest living thing |
| Cell Theory | Three parts: 1) all living things are made of cells 2) Cells come from other cells 3) The smallest thing that can do all characteristics of life |
| Gene Theory | Characteristics of living things are controlled by genes, which are passed from parents ot their offspring |
| Evolution | A change in characteristics of living things over time |
| Natural Selection | The ability of stronger animals being able to reproduce more and pass their genes on more often then weak animals |
| Adaptation | A characteristic that helps a living thing survive and reproduve in a given environment |
| Biodiversity | The diversity of living things on Earth. The huge number of different types of living things on Earth |
| Biome | A group of similar ecosystems with the same general type of physical environment |
| Biosphere | The part of Earth where all life exists including all the: land water and air where living things can be found. The biosphere consists of many different biomes. |
| Community | All of the populations that live in the same area |
| Competition | A relationship between living things that depend on the same resources. |
| Ecosystem | All the living things in a given area together with the nonliving environment |
| Organ | A structure composed of one or more types of tissues |
| Organ System | A group of organs that work together to do a certain job |
| Organism | An individual living thing |
| Population | A group of organisms of the same species that live in the same area |
| Symbiosis | A close relationship between organisms of different species in which at least one of them gets something out of it |
| Tissue | A group of cells of the same kind |
| Unifying Principles of Biology | 4 Things: cell theory-gene theory-homeostasis-evolution |
| 6 Characteristics of living things | 1) Responds to Environment 2) Grows and Develops 3) Produces offspring 4) Maintain Homeostasis 5) Has complex chemistry 6) Is made of Cells |
