| Definition | Term |
|---|---|
| Ex. Why are there different kinds of clouds? Why is one type fluffy while the other is in streaky rows? | questions/observations |
| The observation, identifiction, description, and explanation of natural phenomena. | science |
| observable facts or events in the world around us, like the clouds | natural phenomena |
| educated guesses | hypotheses |
| sight, touch, smell, sound, and taste | five senses |
| STEPS OF THE | SCIENTIFIC PROCESS |
| Identify a problem to solve based on your observations. How can you state the problem as a question for investigation. | Step 1 (Making Observations and Defining the Problem) |
| Research to find out what is already known about your question. | Step 2 (Performing Research) |
| State a hypotheses-that is another way of saying "an educated guess at the solution to your problem." | Step 3 (Forming the Hypotheses) |
| Conduct an experiment or a set of experiments that aim to produce results that will support or contradict your hypotheses. | Step 4 (Setting up the Experiment) |
| Collect and organize your data. What does it tell you? | Step 5 (Collect and Present Data) |
| Analyze the data and summarize the results as a conclusion in terms of the original hypotheses. | Step 6 (Drawing conclusions) |
| looking up information about a certain observation or question | research |
| specialized publication | journal |
| when a journal is scrutinized by anonymous scientists that work in a similar field | peer reviewed |
| This allows you to draw on your observations of specific events to hypothesize a general trend. | Inductive Reasoning |
| This requires yout to use a general truth to hypothesize particular events. | Deductive Reasoning |
| one condition | variable |
| This is designed to give measurable results, which either proves or disproves the hypotheses. | scientific experiment |
| The factors that are changed or manipulated during the experiment (They're the ones that the experiment is trying to test.) | independant variable/manipulated variable |
| the factor that is being measured or counted; the one that changes in response to the independent variable | dependent variable/ responding variable |
| all the other factors in an experiment; these are the things that you attempt to control, and are kept constant during the course of the experiment | control variables |
| when the same result or data is repeating again and again | reproducible |
| the group that will be tested | experimental group |
| the group that the experimental group will be tested against | control group |
| observations made with your senses Ex. color,texture,taste, or smell | qualitative data |
| measurements-anything that can be expressed as a number, or quantified Ex. length,width,weight,time,temperature, or anything expressed as a value | quantitative data |
| (qualitative) validity depends on the person | subjective |
| (quantitative) does not depend as much on the person making the measurement | objective |
| both qualitative and quantitative data can be shown in these Ex. diagrams,graphs, or charts | table |
| patterns in data | trends |
| shows the relationship between things;shows information visually to help understand things | diagrams |
| shows how one variable how the dependent variable changes in response to the independent variable;independent variable plotted on x-axis,dependent variable plotted on y-axis | line graphs |
| used to show parts of a whole(100%)-usually in percentage | circle graph/pie chart |
| compares different things that are not part of a whole | bar graph |
| a judgement based on observation and experimentation;logical statement made from the results of the experiment | conclusion |
| involves using a conclusion as a starting point in inductive reasoning | inference |
| mathematical description of an event;identify correlations and cause-and-effect relations in the phenomena they describe;can be a computer simulation | model |
| forecast of the possible results of events | prediction |
