LET’S

INVESTIGATE:

The Scientific Method

The Scientific Method? What’s it all about?

Click the button to play a song about the

scientific method.

•It is the steps someone takes to identify a question, develop a hypothesis, design and carry out steps or procedures to test the hypothesis, write down data, and draw a conclusion.•In other words, it’s a way to solve a problem.

Scientists take time to think logically when they are investigating a question or problem. They break things

down into many steps that make sense.

1. Ask a QUESTION or identify a problem.

2. Gather information BACKGROUND RESEARCH

3. Formulate HYPOTHESIS.

4. Create an EXPERIMENT to test your hypothesis.

5. Collect DATA or RESULTS by doing the experiment.

6. Draw a CONCLUSION.

Asking questions

All investigations

start with a question !

Do plants need water to grow?

Does exercise make your heart beat

faster?

Background Research

• Gather information by…

• Using the internet,

encyclopedias,

dictionaries,

social interactions,

newspapers, etc.

What question could these children be investigating?

What are they predicting will happen?

A HYPOTHESIS is the same thing as a prediction. It is an EDUCATED GUESS Of what you think is going to happen in your experiment. Example: If I give

plants water, then they will grow.

You need to give a reason why your

hypothesis

is correct.

Example: …..because water is a key component to Photosynthesis.

2 parts to a Hypothesis

1.Dependent Variable- Cannot control outcome

2.Independent Variable- Can change or manipulate the factors

What are these two finely dressed children investigating?

What is their HYPOTHESIS?

The next step scientists take is to create and

conduct an experiment to test their hypothesis.

In every experiment, we Must have 2 things…

Materials and Procedures….

A key to experiments is observing what happens and writing it down.

Gathering information or data is very important. Write it down so it is readable and makes sense to other people who read it.

After the experiment, you need to write in detail what happened in your experiment.

Example: What happened?

Photos, graphs, charts, videos, etc…

You need to look back at your HYPOTHESIS and see if you were correct!

States if your Hypothesis was proven true or false!!

Your hypothesis does not have to

be correct!!

You need look at the problem and create an

original Hypothesis

Remember to team up with your color lab
