Step #4 - Plan, conduct & write up your experiments (Grades 2-5)

Once you've Formed Your Problem Statement and Hypothesis (2-5), its time to Plan, conduct & write up your experiments.  If your Project is for Grades K-1, click here to switch to K-1 page.

Science Journal
Start with a new notebook and write all of your notes about your science project in this notebook.  This will be your science journal and will be a part of your final project.  Every time you work on your science project, start on a new page and write down everything that you do or think.  Label each page with the date and time.  If you type your notes using a computer, plan to print the journal and submit with your final project.

Plan your experiment.
Write the steps of the experiment that tests your prediction in your science journal.  Write neatly or type and completely so that another student could use only your notes to perform your experiment exactly as you have done. Include a list of materials as well as a list of safety concerns.

Variables (2-5 Only)
Determine the things you will change in your experiment to prove your prediction or hypothesis. The things that you change are known as variables.  For example, you might make the variable water temperature testing both hot and cold water.  Write in your science journal the variables that you will change, how you change these variables, how you measure the impact of the change and how often you record these measurements? 

Include the variables below.
1 variable changed (manipulated)
1 variable measured (responding)
1 or more variable kept the same (controlled)

Procedures/Materials/Safety Concerns
Your experiment plan in your science journal should include a list of materials that you will use. Do not use name brands. Repeat your experiment several times.  Repeating experiments is known as multiple trials and scientists repeat their experiments many times to confirm that they understand the behavior. 

In your list of the steps, be sure to include any safety concerns with this project or the clean up afterwards.

While you conduct your experiments, be sure to observe carefully and take notes in your science journal. Collect data using measurements in your science journal with your notes and data (measurements), drawings of the experiment, charts, graphs and pictures.  After you've cleaned up your experiment, your science journal is all that's left so be sure to write down everything about your experiment.
