Collecting Data when doing the Scientific Method

Collecting Data for Science Fair Projects

This week you are collecting data when following the scientific method. You do this after you complete doing your science fair experiment.

During this step of the scientific method you will be doing two things, (1) completing your experiments and (2) collecting data. This step can take anywhere from a few minutes to several months depending on the complexity of your project.

Before you start working on your experiment, you will want to set up your data collection system. A notebook is a great tool to use to collect your data. If you use a data collection journal you will want to standardize your entries. Each entry that you make will need to include the date, time, observations and specific data measurements and readings. The second option that you have is to create a data collection form. This form will include spaces for the specific pieces of information that you need to collect.



As you’re collecting data make sure you also collect graphics for your project. For example, when working on astronomy projects you will want to take photographs through your telescope or create drawings of your observations. These will help you when you analyze your data in the next step, as well as help you to put together a winning display.

If there are a lot of observations that need to be made during your experiment then you have a couple of options. First you can have someone help you make observations and collect data. Your second option is to video record the experiment. Both of these options will give you a second pair of eyes that will allow you to collect as much data as possible from your experiments. They will also make sure your results are more accurate.

    Collecting data is probably the funnest portion of the actual project. That’s usually when the actual experiment is done, or if there is no experiment per say that’s when you go out and explore some phenomena, which is the most exhilarating part of a project for most kids.
