Science Buddies: "Ask an Expert"

My Daughter wants to start this project for her science fair in Woodlands TX. She had a question : Can this be designed to add decrease in glucose levels as we have members in our family who also suffer from low sugar. How do i add her into this account as well?

Hi - I deleted the email address that you posted, please do not post personal contact information in the forums. All our questions and answers are done directly in the forums. If your daughter would like to ask questions directly, she can create an account on the Science Buddies website and post here.

To answer your question, please see Table 1 in the introduction of the project. You can add tap water to the distilled water, which simulates adding insulin, but you can also add more distilled water, which simulates eating carbohydrates. You could do this process manually just by pouring in more distilled water, or you could hook up a second pump with another container of distilled water to pump it in automatically. Hope that helps!

Thank you for your response and keeping my daughters email address safe!

As we embark upon this project, is there a step by step approach for building this tool?

The only step by step instructions (with exact parts lists, circuit diagrams, etc) are what's available on the project page here:

Adding or changing things to those exact instructions is up to the individual student. If your daughter has never worked with circuits, programming, or an Arduino before, I would suggest that she start with our How to Use an Arduino tutorial series before tackling this project:

That will provide a much gentler introduction to many of the basics, and hopefully give her more confidence when modifying an advanced project.

Please don't hesitate to write back if you have more questions.
