What is the purpose of inquiry design? Inquiry/Experimental Design is a series of steps used to investigate natural occurrences/phenomena

What are the steps of the Experimental/Inquiry Design? 1.Observations 2.Ask Question/ Define Problem 3.Research 4.Hypothesis 5.Experiment 6.Collect Data 7.Analysis 8.Conclusion/ Follow-Up

Identify the different types of Observations Qualitative-Using the 5 senses –Touch –Smell –Taste –Sight –Hearing Quantitative-Anything measurable –Scales –Rulers –Beakers

Why is it important to do research and make observations when you identify a problem? It is important to conduct research on a problem you have identified so you can find out if someone has already figured out an answer. If there is no answer, use the research you find to create a hypothesis. Identify Problem/Question

What is a hypothesis? A hypothesis is a possible answer to a question. Hypotheses are typically written as an if…then…because statement. Form a Hypothesis

How do I write a Hypothesis If (restate the problem) then (what do you predict will happen) because (reasons to support your prediction based on your research)

How do I write a Hypothesis Example: If you study a little every day, then your test scores will be higher because you have taken an active role in your education.

What are some important things to include in an experiment? It is very important to include a materials list and a detailed procedure when doing an experiment. Experiments need to be repeated to verify the results Experiment

Differentiate between the different groups used in an experiment. Control Group: Used for comparison. All variables are the same as the experimental group EXCEPT the variable you are testing Experimental Group: Change one variable to find out if that variable has an effect on the test subject

What are the variables in an experiment? Independent Variable: –the variable that can be controlled by the experimenter. It usually includes time (dates, minutes, hours), depth (feet, meters), temperature (Celsius). –When Graphing; this variable is placed on the X- axis (horizontal axis). Independent Variables

What are the variables in an experiment? Dependent Variable: –the variable that is directly affected by the independent variable. – When Graphing; this variable is placed on the Y-axis or vertical axis. Dependent Variables

What are the variables in an experiment? Controlled Variables: –EVERYTHING THAT REMAINS CONSTANT IN AN EXPERIMENT. Variables

Describe the different types of Variables Variable - Any factor that can change Independent: The part of the experiment that YOU (the experimenter) change (X-axis) Dependent: The part of the experiment that you measure (Y-axis) Controlled: Parts of the experiment that remain constant in both groups

What are trials? Trials refer to replicate groups that are exposed to the same conditions in an experiment. The greater number of trials increases the validity of the experiment. Trials

How should data be collected? Collect data throughout the experiment. Put data into data tables and/or graphs. (TAILS) Collect Data and Analyze Results

What should the conclusion consist of? The conclusion is a written statement that states whether the hypothesis was accepted or rejected. The conclusion should also contain recommendations for further studies or improvements to the procedure. Conclusion
