Science is a tool for telling you what works!A scientific theory explain what is seen and predict what will happen in the future.How do you know if your theory (idea, model, hypothesis) is right? - You can test it!
THE ORIE S - GUE SSE S - LAWS• What does the word “Theory” mean to you? “A conjecture; guess” (Webster’s Dictionary)• Does it mean the same to a scientist? “A model which has been born out by repeated tests and observation.”• Is a Theory less than a Law? “Evolution is just a theory, it is not a fact.”• Do Theories “grow up” to be Laws? “Einstein’s Theory of Relativity”

Take a closer look at these steps and thescientific terminology before we start ascience based project
Develop a question or problem that can be solved through experimentation Scientist have to take the time to think logically whenScientists break things they are investigating adown into many steps question or problem. that make sense
Scientists develop a question, gather information and form an hypothesis.
Predict a possible answer to the problem or question by FORMULATING HYPOTHESIS.
Make in depth OBSERVATIONS and RESEARCH on your topic of interest
TRIALS refer to replicate groupsThe next step scientists take is to that are exposed to create and conduct an experiment the same to TEST their hypothesis. conditions in an experiment.
EXPERIMENTDevelop and follow a procedure and theoutcome must be measurable (quantifiable).
A key to experiments is observing, gatheringinformation, collecting data, and DOCUMENTING it so itis readable and makes sense to others or peer group.
Modify the procedure if needed. Confirm the results by retesting. Include tables, graphs, and photographs.
VERIFYING or checking of data andresults obtained is very important tomake sure everything was valid and will repeat again and again. Once a scientist completes an experiment, they often REPEAT it to see if they get the same findings and results.
Include a statement that accepts or rejects the hypothesis.
Make a NEW recommendation for further study and possible improvements
Scientists share their experiments and findings with others.
