DefinitionTerm
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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
