Term | Definition |
Scientific Method | a series of steps used to answer a question or solve a problem |
Hypothesis | a possible explanation or answer to a question, and it uses the word "affect" |
Prediction | an IF-THEN statement that states in advanced the results of the experiment |
Variable | what is being studied |
Control group | when the variable in not changed; used for comparison |
Experimental group | has one variable that changed |
Independent variable | what changed in the experiment |
Dependent variable | what changes due to the independent variable |
Controlled experiment | tests one variable at a time; containing a control group, experimental group, and a variable |
Theory | Current explanation of why or how something happened |
Law | explains what happens in the experiment that over time is proven to be true |
Label the 6 steps of the scientific method | State a problem, form a hypothesis and prediction, design the experiment, perform experiment and analyze results, draw conclusion, and communication |
What do scientist do in step one- state a problem? | Gather information by making observations and asking questions |
How do scientists make observations? | Use one or more of your 5 senses to identify objects or events |
What do you do when designing the experiment? | Test the hypothesis |
What groups and variables are in the experiment? | controlled group, experimental group, independent variable, and dependent variable |
What do scientists do during step 4- perform experiment and analyze results? | Collect data, look for patterns in data of the experiment, and do the experiment many times with many subjects to make sure analyzing and conclusions are correct. |
What do scientists do during step 5- draw conclusion? | State results, check to see if the results support the hypothesis, and they explain why or why not |
What do scientists do during step 6- communication? | Use lab reports, articles, and presentations to explain research and results, and they may repeat their experiment again with other people's ideas and suggestions. |
Why is it important to do an experiment more than once? Should a scientist have a large or small number of subjects in an experiment? Why? | A large number of subject in an experiment helps make sure analyzing and conclusions are correct. It increases the reliability of the research. |
