Observe the natural world What do you see? What can you question? What don’t you understand about what you see? Learn to question things… that’s where science begins!!!
4
Usually written in the form of a question Your problem must be TESTABLE! The problem is the question you want answered by doing an experiment!
6
Research allows you to find out some background information that might be necessary for designing your experiment. You may want to look up past experiments that have been done. Research is used to support your hypothesis!!!
7
Definition: POSSIBLE ANSWER TO THE PROBLEM BASED ON PRIOR KNOWLEDGE OR RESEARCH!!! Not an educated guess!!! Written in the form of “If…Then… Because…” If… = Experimental setup Then… = What you think will happen Because… = Why will it happen (research) NO Personal Pronouns!!! If 4 rose plants are given different amounts of water, then the plant given the most amount of water will grow the tallest, because water is required for a plant to grow.
8
List everything you plan to use in the lab This includes all equipment, along with any solids or liquids you are going to need. Use a bulleted format! 200 ml water 10 g sodium chloride 400 ml beaker Triple-beam balance Glass stir rod Not: 200ml water, 10 g sodium chloride, 400ml beaker, triple-beam balance, glass stir rod
9
Step-by-step Numbered list 1. 2. 3. Specific and detailed Someone else has to be able to follow your exact experiment!
10
Controlled You are only testing one variable Multiple trials Large # of individuals Has to relate to your problem (question)

13
Written in paragraph form Refer to your hypothesis Restate your hypothesis Did you support or refute your hypothesis? Why? Refer to data to support or refute your hypothesis. Discuss any errors that occurred. NO Personal Pronouns!!!
14
Written in paragraph form Did you find an answer to your problem? Refer back to research to support your findings. What additional experiments could you do to improve your results or get a better answer? More specimens Multiple trials Fix errors NO Personal Pronouns!
