DRILL: Look at the image below. Write down what it is, AND how you know using complete sentences.

Are you sure? Look closer…

Announcements  All classroom materials need to be with you by tomorrow!  1 2” binder  Loose leaf paper  Tab dividers  Pens/pencils  If you have problems getting the materials, talk to me about it during independent work.  Scientific Method test September 7 th.

Agenda  Dice, Dice, Baby for identifying variables  Quick review of scientific questions  Research our question  Hypothesis

Why?  Scientific questions are important because they drive our insight into something we’ve never done before. Imagine the world without the internet. This would be our reality today if Time Berners-Lee never asked the question, “How can we exchange information through computers?”

Group Work  Raise your hand silently if you have ever played the game Dice, Dice, Baby.  RULES:  You need to get out one piece of paper between you and your partner and then split it in half.  YOU EACH SHOULD HAVE A HALF OF THE PAPER!  Do not write on the paper!

Dice, Dice Baby  You will be getting 1 die between the two of you.  Partner 1 will roll the dice until they get a 6.  While partner 1 is rolling, partner 2 is going to be identifying the independent, dependent, and control variables for a series of questions.  When partner 1 rolls a 6, they will grab the pen out of the partners hand (GENTLY!).  This game can get intense fast. Let’s try not to hurt each other

Is it good or bad?  Is chocolate better than fruit candy?  How does the amount of chocolate a person consume effect their ability to focus?  Does the amount of chocolate effect a person’s weight?  Is it sunny outside?  Do we need to go to school today?  How does the amount of attitude a student gives effect a teachers amount of yelling?

We have a question… So what?!?!  Before we are able to create our hypothesis, we need to do some research in order to avoid this….  c&list=PL3AA2D479A1744E37&index=1&feature=pl pp_video c&list=PL3AA2D479A1744E37&index=1&feature=pl pp_video  When I say “research,” I’m not implying that we all need to run to the library.  Sometimes, the research that we will do will be simply reading some background information, and sometimes it’ll be more in-depth.

Hypothesis What do you think will happen? A hypothesis is your prediction for the outcome of the experiment. It is based on your observations and should be testable! Your hypothesis should be written in the following format: If…… then.….because… Example: If I come to class everyday then I will earn a better grade because I am present to learn the material for the test

If, then, because…  IF: What you do  IE: If I drop a book,  Then: What you think will happen  IE: then it will fall  Because: Why you think it will happen  IE: because gravity pulls objects back down to Earth.  Hypothesis: If I drop a book, then it will fall because gravity pulls objects back to the ground.

Let’s try one together.  Look at your handout.  Let’s answer Part 1, Question 1 together.  Question: What effect does the water temperature have on solution rate?  Do we have enough info? Why or why not?  On your handout, read the short blurb about heat and solution rate.

Group practice  In your partners, you’ll be answering the rest of the hypothesis questions on the sheet.

Exit ticket  You walk into lab tomorrow and see that I have laid out a container of salt, a beaker full of water, a hot plate, and a container of sugar. By yourselves, you will be using these objects to create an experiment. 1. Create a scientific question that you could test. 2. Identify the different variables.
