2 Choose a Problem What do you want to learn more about? Ask a specific questionEx 1:Do plants need water to grow?Ex: 2:Is Mr. Pullins the best teacher of all time?
3 Research Your Problem How can you find the answer to your question? LibraryInternetAdultsYour own background knowledge!
4 Develop a Hypothesis THE What do you think the answer to your question will be?Hypothesis-A statement that tries to explain a relationship between two variablesTHEThey’re sisters…
5 Still Developing Hypothesis… Use the words IF and THENEx 1:IF you water a plant more, THEN it will grow tallerEx 2:IF Mr. Pullins is your teacher, THEN you will become a genius!IF IF IF IF IF IF IF IF THENTHEN
6 Still Developing Hypothesis… What is a variable again?Variable:Anything that can be changed or manipulated during an experimentEx 1:Type of plant, amount of water, sun exposure, etc.Ex 2:Time of day with Mr. Decker vs. Pullins, how much time spent, etc2A + 3 = 72B + 3 = 72C + 3 = 72D + 3 = 72E + 3 = 7
7 Write Procedures How will you test your hypothesis? List materials List each thing that you will doNumber each stepWrite down EVERYTHING you will doAnyone should be able to replicate your experiment
8 Test Your Hypothesis Obtain materials Conduct experiment Follow your procedure… exactlyBe sure to control your variablesVariable-Anything that can change or vary during an experiment
9 Controlling Variables You need to know exactly what you are testing……You have to control EVERYTHINGThree different types:Independent variableDependant variableControl variables
10 Independent Variable Independent variable- Example hypothesis: The variable that you are changing or testingExample hypothesis:IF you water a plant more, THEN it will grow tallerWater is the independent variableIt will always be the IF portion of your hypothesis
11 Dependent Variable Dependent variable- Example hypothesis: Changes in response to the independent variableThe variable you are measuringExample hypothesis:IF you water a plant more, THEN it will grow tallerPlant height is the dependent variableIt will always be the THEN portion of your hypothesis
12 Control Variables Control variables- Example hypothesis: Variables that are unchanged throughout the experimentExample hypothesis:IF you water a plant more, THEN it will grow tallerControlled variables:Soil, age of plant, type of plant, amount of sunlight, etc..
