Welcome back minions! MINIONS ASSEMBLE!!!
QUIZ (sort of) TIME!!! Clear your desk!
Welcome to curiosity!!! • Scientific Inquiry – different ways scientists study the natural world.
The Process of Inquiry… • Posing questions • Developing Hypothesis • Designing Experiments • Collecting & Interpreting Data • Drawing Conclusions • Communicating Ideas and Results
Posing Questions • Need to ask appropriate questions for scientific inquiry. • Does Mr. Scott have the cutest kitten? • What type of cat is the most adorable? • Which pet food makes your cat fat the quickest? These questions cannot be based on values, opinions, or judgements.
Developing a Hypothesis • Hypothesis – A possible answer to a scientific question or explanation for a set of observations. • Best method is the “If… then…” statement. • “If brand X uses more filler than the rest, then the cat will gain more weight than it would with other brands.”
Developing a Hypothesis • A hypothesis is NOT A FACT!!! • It is one possible way to answer a question. • It must be testable by observation or experiment! • Many trials are needed!
Designing an Experiment • First you must examine the variables. • In a well designed experiment, only one variable is changed. • The changed variable is the “manipulated variable” or “independent variable”. • The variable that is expected to change is the “responding variable” or dependent variable”. • All other variables must be controlled (kept constant or not changed). • An investigation where all variables except one remain the same is called a controlled experiment!
Collecting and Interpreting Data • Create a data table for recording data. • Data – facts, figures, and other evidence gathered through observations. • Observations can be qualitative or quantitative. • Interpret or explain data. • Easily done through graphs.
Drawing Conclusions • A conclusion states whether or not the data supports the hypothesis. • Even if your data does not support the hypothesis, it is still valuable information! • It can help you draw alternative hypotheses!
Communicating • A very important part of the process!!! • Communicating – Sharing ideas and conclusions with others through writing and speaking. • Why is this important?
Worksheet! • Terms to know… • Control – • A group within an experiment that is not changed or experimented on. • Variable – • The factor that can change in an experiment. • Independent Variable – • (aka: manipulated variable) • Dependent Variable – • (aka responding variable)
