Conducting an Experiment Eric Angat Environmental/Physical Science Teacher

How do I conduct and experiment? Essential Question How do I conduct and experiment?

1. What is the Scientific Method it is an organized way in figuring something out.

2. What are the 5 steps of the Scientific Method 1. Ask a question. 2. Form a hypothesis. 3. Design and conduct an experiment. 4. Analyze the results of the experiment. 5. Draw a conclusion.

3. Why is the scientific method important? http://www.youtube.com/watch?v=x2606GQmDqY&safe=active http://www.youtube.com/watch?v=x2606GQmDqY&safe=active

Why is the Scientific Method important? Because when the scientific method is used to solve a problem. The procedure can repeated by anyone and verify the result/s.

4. What are the parts of an Experiment? Independent variable ( IV ) Dependent variable ( DV ) Control group Experimental group

Independent variable (IV) is the factor that you change in the experiment. Dependent variable ( DV ) is the factor that we measure. It is the result of the independent variable.

Control group is the one that remains the same throughout the experiment. Experimental group is the one that you manipulate or change in the experiment.

Copy and answer the following Questions in your Notebook. 1.What was tested in Mr. Koning’s experiment? 2. Why was Jacob’s suggestion regarding the experiment not accepted by Mr. Koning? 3. How many Independent variable (IV) should there be in an experiment? 4. What was the independent variable in the experiment? 5. What was the dependent variable or measured data (DV) in the experiment? 6. What were the control variables ( CV)?

1.What was tested in Mr. Koning’s experiment? 2. Why was Jacob’s suggestion regarding the experiment not accepted by Mr. Koning? 3. How many Independent variable (IV) should there be in an experiment? The rate of plant growth. Because Jacob was changing so many variables. One variable only.

4. What was the independent variable in the experiment? 5. What was the dependent variable or measured data (DV) in the experiment? 6. What were the control variables ( CV)? Amount of water. Plant growth rate measured in centimeters. Amount of sunlight, type plant, soil, humidity, temperature, and location.
