​Step 1: Ask A Question

​The question is something specific that you want to learn.

​

On the next five slides choose good if it is a good question or bad if it is a bad question.

Replace this with a sub-header that can be in multiple lines. ​

Duplicate this text as many times as you would like.

​Step Two: Collect Data about your problem

​

​Learn everything you can about the problem.

You can't solve a problem without gaining knowledge about the problem.​

Why is it important to collect data before you try to solve a problem?

​Some text here about the topic of discussion.

​Step Three: Form a Hypothesis​

​

​A hypothesis is a possible solution or answer to the problem.

It is based upon​ the information you collected about the problem.

It is never a wild guess!​

It is never stated in the form of a question.​

Multiple Choice

A hypothesis is

• The same as the problem

• A wild guess

• A possible solutiong to the problem based on hunch

• A possible solution based on data collected about the problem

Multiple Choice

A hypothesis is stated in the form of a question

• True

• False

Multiple Choice

What must always be done before you form a hypothesis (a possible answer to a problem).

• Research the problem

• Conduct an experiment so you can form a hypothesis

• Decide how you can prove that the hypothesis you are going to form is true

​Some text here about the topic of discussion.

​Step Four: Test the Hypothesis

​

​A hypothesis must be tested in order to prove if it is the correct answer or not.

A hypothesis is proven by conducting an experiment.

In order to conduct an experiment you must identify the independent and dependent variables and the controls.​

Types of Variables

​Independent Variable

​An independent variable is what the person conducting the experiment changes.

Some text here about the topic of discussion

​Dependent Variable

​Anything in an experiment that could be changed but is kept the same

​Controls

Types of Variables

Some text here about the topic of discussion

​The results of the experiment.

​Work handout on identifying variables.

​Step Five: Collect and Analyze Data

​

​Data must be collected during the experiment. This data will be used to determine if you hypothesis is correct or not.

​Step Six: Determine if your hypothesis is correct

​What do you do if your hypothesis is wrong?​

​Based on the data collected in the experiment you will decide if your hypothesis (possible answer to the problem) is correct or not.

​Some text here about the topic of discussion.

​What to do if your hypothesis is wrong.

​

• ​Go back and do some more research.

• Form a new hypothesis

• Conduct a new experiment

• Record and analyze data

• Form a new conclusion.​

Multiple Choice

Which of the following should be done if the experiment proves that the hypothesis is wrong.

• Form a new hypothesis based on the experiment that was conducted

• Change the old hypothesis to make it fit the results

• Give up. There's no use trying

• Go back and do more research, form a new hypothesis and conduct a new experiment
