LS.1 a-j The student will plan and conduct investigations Scientific Method Series of organized steps used to solve a problem Used by scientists and people around the world 6 main steps Observation & Stating the Problem Research Hypothesis Experiment Analyze Data Conclusion LS.1 a-j The student will plan and conduct investigations
1. Observation & Stating the Problem All 5 senses (sight, smell, hearing, feeling, taste) Gather information (just the facts) Ex. The board is black Stating the Problem What could change or what causes what was observed? Infer Use observation & what you know to state what has happened Ex. The board may be black b/c it doesn’t have chalk on it. LS.1 a-j The student will plan and conduct investigations
LS.1 a-j The student will plan and conduct investigations Observation Practice LS.1 a-j The student will plan and conduct investigations
LS.1 a-j The student will plan and conduct investigations 2. Research Gathering information About the problem Experiments others have done Print Books Science journals/ magazines Non-print People Internet LS.1 a-j The student will plan and conduct investigations
LS.1 a-j The student will plan and conduct investigations 3. Hypothesis Educated guess Based on research If…. then statement Shows how two variables are related Variables Things that can change in an experiment 3 types Independent Dependent Controlled/Constants LS.1 a-j The student will plan and conduct investigations
LS.1 a-j The student will plan and conduct investigations Variables Independent You change on purpose Manipulated variable IV Control Shows that its only the IV that causes the effect Receives none of the IV (no change) The standard used to compare with the outcome in an experiment Dependent Reacts/ responds to changing IV DV What you measure in an experiment Controlled Variable= constants Things that can change, but you do not allow them to LS.1 a-j The student will plan and conduct investigations
LS.1 a-j The student will plan and conduct investigations Quiz 1 An observation uses _____ to gather information. The _______ is changed on purpose in an experiment. A ________ is an educated guess. Anything that can change in an experiment is called a _______. LS.1 a-j The student will plan and conduct investigations

Format for Writing a Hypothesis If the __IV__ __(changes this way)__, then the __DV__ will ___(change this way)___. Ex. Plants in the sun seem grow taller than plants in the shade. IV = amount of sunlight DV= height of plant Hypothesis: If the amount of sunlight increases then the plants height will increase. LS.1 a-j The student will plan and conduct investigations
LS.1 a-j The student will plan and conduct investigations 4. Experiment Procedures used to test a hypothesis at least 3 trials for each type of IV Has Constants Not allowed to change Make more accurate Gives data Quantitative Qualitative LS.1 a-j The student will plan and conduct investigations
