Steps of the scientific method
Q= R= S= T= U= V= Observation Problem Question(Hypothesis) Research (Background Information) Set up a controlled experiment Test and analyze data Understand (Form a conclusion) Verify (Replicate work)

Observation vs interpretation
Observation: The act of observing and recording scientific phenomena (or “Just the facts”) Observations can be made using the 5 senses seeing, hearing, smelling, feeling and tasting 2 types of observations Quantitative Qualitative

2 types of observations Quantitative observations: are numbers, these numbers must have a consistent reliable value (ex. 10m or 75 degrees F) Qualitative Observations: are recorded as non-numeric values or descriptions (ex. Red, hot, large, loud…)

These can sometimes be opinions, versions
Interpretation Interpretation: more than just the facts and cannot be accurately proven. These can sometimes be opinions, versions

Controlled Experiment
Controlled experiment: is an experiment that tests one variable against the “normal” conditions Variable: what you change 1. Problem: What you are trying to answer 2. Hypothesis: what is a possible solution or outcome to the problem. (IF….Then) 3. Experimental design (Ex’D)

Experimental Design (cont.)
A. Independent Variable (IV): What is being manipulated or changed in the experiment you control B. Dependent Variable (DV): What is being measured in the experiment- Data being collected C. Control: Experimental group that is under the “normal” conditions—What your DV results are compared to D. Constants: all conditions that must remain the same or unchanged between the experimental and control groups
