Writing A Hypothesis

Writing a Hypothesis L.O. — Students will understand how to write a testable question and a hypothesis and then proceed to do so.

Reminders I Bring me your textbooks—or else. I should see two outlined sources by the end of the period. If I haven’t seen your research planning sheet (given out yesterday) or your second source yet, I need to see it by the end of the period.

Reminders II Don’t get out of your seat for any reason at all. People are working and I’m conferencing, please keep a respectful tone. First Warning—10 points off classwork grade. Second Warning—Zero in classwork for the day (separate from your project grade).

Upcoming Deadlines Tomorrow: Field Trip to the Botanical Garden Friday: Revised proposals due. Friday: Bring in your third source. Monday: All three outlines due to me for review.

Experimental Design Your project should have a testable question. A testable question is one that is answered by experimentation, not by the turning of pages in a book.

Answering a Testable Question The answer to a testable question is typically developed by identifying and controlling variables and reﬂects the elements of a well- designed investigation such as multiple trials.

How to Answer a Testable Question A testable question can often be written in the form quot;How does _____ affect ______?quot;

Hypotheses Your hypothesis is an educated guess to your testable question based on the research you’ve done so far. It’s like a topic sentence.

Writing a Hypothesis It’s often an “If... then... because...” statement. If the temperature of a gas is increased, then the volume will increase. If the length of a pendulum increases, then the period of swing will decrease.

What needs to be done today. You should have your ﬁrst two outlines done. You should have a testable question and your hypothesis for your project written and submitted to me. If you ﬁnish early, you can work on your revised proposal or begin drafting your research paper.
