Planning the Investigation
Careful planning makes an investigation run smoothly.
Before you go on an outing, you plan what you will need and what you will do. That way, your outing will go smoothly. Different outings require different equipment and supplies.

The same is true for a science investigation. Different science investigations require different tools and equipment. Different investigations also have different steps. What you are trying to answer

For example, should you do your investigation indoors or outdoors? If you are studying changes in the population of robins in your neighborhood, you will work outdoors. If you want to find out what causes a bottle of cold soda to suddenly fizz when you twist off its cap, you will probably work indoors.

Before you begin your investigation, list the steps you will follow. Important steps are listed here. You might want to add more steps, too.

4. Find out whether there is anything dangerous in your investigation. Find out how you can do the investigation safely.
2. Decide what equipment you will need for your investigation and where you can get it.
