1. How we do science… The key to inquiry investigations

2. Questioning…Questioning… Asking the right questions related to scientific inquiry

3. Questioning Skills Scientific questions need to be answered by observations or evidence If questions cannot be answered by gathering evidence, it’s not science They should identify a relationship or a factor you can investigate

4. Hints to help! If your questions are general, break them down into questions that can be investigated one at a time A good question is structured as follows: –‘‘What is the effect of ____________ on ______________.”

5. Writing A Proper Hypothesis Writing A Proper Hypothesis Using the “If / Then” Method

6. Parts of the Statement Independent Variable: The condition be studied. It is controlled by the experimenter. ex. Water Dependent Variable: The condition affected by the independent variable. It can’t be controlled by the experimenter. ex. Plant Growth Control Variable: Other factors that could affect or be affected by the experiment. Try to eliminate or reduce these variables. Control: The condition that is represented in a ‘normal’ situation (what happens with no manipulation).

7. What kinds of variables? Most common are: –Time, temperature, length, width, height, mass, volume, distance, number, and kinds of substances being used in the experiment.

8. Steps to Writing the Hypothesis 1.Start your sentence with the word “If” 2.Write down the independent variable 3.Connect statement with is increased/decreased/stays the same 4.Write down “then” followed by the dependent variable will increase/decrease/stay the same.

9. Example of the format of a hypothesis Ex. If section: If the amount of water is increased Ex. Then section: then the height of the plant will increase. Final “If / then” statement: If the amount of water is increased then the height of the plant will increase.
