How to Write a Science Project Question
An Experimental Science Project is a Cause/Effect investigation. In other words, the change in one thing causes something else to change.
The “Cause” part of the investigation is what you will have control over.
The “Effect” part of the investigation is what you will be observing to decide if or how it changes. The “Effect” part of the investigation depends on the “Cause” part.
In science investigations, any thing that could change and affect the results is called a variable.
You only want two variables, the Causing variable, which is known as the independent variable, and the Effect variable, which is known as the dependent variable.
There are many things that could affect the results of an experiment, such as temperature, water, light, humidity, etc….You want all variables kept constant if possible except the independent and dependent variables.
1. Decide on the topic you want to investigate.
Example: The germination rate of seeds.
In other words, you want to find out how long it takes for seeds to develop into a plant. Since there are many kinds of seeds, you need to select one kind of seed. For this example, I am selecting Chia Seeds.
So far, I have decided that I want to investigate the germination rate of Chia seeds. Now I need to decide on one thing that might affect chia seed germination. I don’t know much about Chia seeds so research is needed.
2. Read about Chia seeds, then make a list of things that might affect the germination of chia seeds.
For Examples: Growing Medium, which is what the seeds grow on or in.
There are many different online resources for how to grow chia seeds, one is Carolina Pet Supply.
Your science project question is:
How does the growing medium affect the germination rate of Chia seeds.
