Interactive Notebook (comp. ntbk) • Set Up your notebook so you have an “In” “Out”, “Through” format. • “In Activity”: What is Science? List two things! • Body of Knowledge (Bunch of information) • Process (scientific method)
SCIENTIFIC METHOD NOTES Name_____________ Per______Date_____
Steps of the Scientific Method • Observation: Use the 5 senses to observe • Question: Create a scientific question • Hypothesis: Create a prediction • Procedure: Write the steps of the experiment • Collect and Record Data: Build a data table. • Conclusions: What does the data tell you?
Make an Observation Step 1 Observation involves using all 5 senses to gather information. These senses are: • sight • hearing • touch • smell • taste You might observe the plant wilting and turning brown.
Making Observations Step 1 • Take a moment to observe a penny and draw a diagram of your observations on your notes page.
Posing a Question: Step 2 • A scientific question is one that can be answered by gathering evidence. (Testable) • “I wonder why my tomato plant died?”
Practice: Scientific Question or Not? • Look at the following questions and decide which are scientific (testable) and which are not. • What is the effect of cigarette smoke on lungs? • Why is blue the best color in the world? • Why did the grass turn brown? • What is the effect of study time on test grades? • Why is basketball a boring sport?
Scientific Question or Not? • What is the effect of cigarette smoke on lungs? Scientific • Why is blue the best color in the world? Not Scientific • Why did the grass turn brown? Scientific • What is the effect of study time on test grades? Scientific • Why is basketball a boring sport? Not Scientific
Hypothesis Step 3 • A possible explanation that relates to a scientific question. • Must be testable by observation • If…..then….because • I predict….. because • Example: If I don’t expose my tomato plant to enough sunlight, then it may die because sunlight is needed for the photosynthetic process.
Procedures (Design Your Experiment) Step 4 • A very detailed list of instructions that can be understood and repeated. • Use numbers or bullets for each step. (Numbers are better.)
Practicing Procedure Writing • Write the procedure for tying a pair of shoes. • Be detailed so someone else can follow your procedure. • Use a numbered list.
Variables • All the factors that can change during an experiment. • Three main types, controlled variables, manipulated variables and responding variables.
Controlled Variables • Controlled variables are found in controlled experiments where two or more objects are compared. • These are the variables that are kept exactly the same in two tests. (Same kind of plants, same amount of soil, same amount of water, etc…)
Manipulated Variable (Independent Variable) • This is the one variable the scientist changes. (Amount of sunlight.)
Responding Variable (Dependent Variable) • The variable that is expected to change because of the manipulated variable. (The tomato plant’s growth.)
Data • The facts, figures and other evidence that you learn through observation are called data. • Data comes in two forms, qualitative and quantitative data.
Qualitative Data • Qualitative data is data that describes color, odor or sound. This data does not involve measurement or numbers.
Quantitative Data • Quantitative Data are measurements made using standard units, such as mass in grams (g) or density in grams per cubic centimeter (g/cm3)
Collect and record Data Step 5 • Use a data table for recording numbers, descriptions, and other observations.
Interpreting Data Step 5 • Scientists identify trends or patterns within the collected data to figure out what they mean. (My tomato plant grew taller over a period of days with more sunlight.)
Drawing Conclusions: Step 6 • A conclusion states whether the data supported the hypothesis or showed it to be false. (My hypothesis was correct; my tomato plants did need more sunlight to maintain healthy growth.)
