2 Notes 1. Scientific Method- a series of steps used to solve problems 2. Observation- information gathered with your sensesSight, sound, touch, taste, & smell3. Inference- a conclusion based on an observationRemember the “shoebox activity”
3 Observation & Inference The temperature of the glass of water near the window is warmer than the one on the shelfThe sun must have been shining on the waterOBSERVATIONINFERENCE
4 Observation & Inference The bell rangIt is dismissal timeObservationInference
5 Observation & Inference The clouds are very darkIt is going to rainObservationInferernce
6 4. Hypothesis- a prediction or statement that can be tested 5. Independent Variable- the experimental treatmentThis is the factor that is different from the other group6. Dependent Variable- what is being measured or observed.
7 7. Constants- factors that STAY THE SAME in both parts of an experiment 8. Control- part of the experiment that does NOT receive the experimental treatmentIt is the group to which the experimental group is compared!

9 Scientific Method- a series of steps used to solve problems Ask a Question or Recognize the Problem- decide what you want to understand by performing an experiment
10 Hypothesis- a prediction or statement that can be tested Observe & Infer- gather information using your senses and make conclusions bases on what you observed.Hypothesis- a prediction or statement that can be testedIt is based on observations, research and prior knowledge.Often written as a “If …, then…” statement.
11 Dependent Variable- the factor or part that is being measured or observed Independent Variable- the experimental treatmentWhat is being changed during the experimentThe factor that is different from the control group.
12 Constants- factors or parts of the experiment that stay the same in all parts of the experiment. Control- part of the experiment that does NOT receive the experimental treatment (independent variable)This is used to make comparisons and to see how the experimental treatment works.
13 Analyze the Data- data can be numeric, such as measurements, or observations and descriptions. Draw Conclusions- make a statement based on the data collected and state whether or not the data supports or rejects the hypothesis.
