Project Overview

Materials List

Parent Letter

Please include a copy of the parent letter in your packet home. This informs parents of the sampling process, explains what their student is doing, talks about privacy, and asks for various permissions. The permission slip should be returned to the teacher and mailed to when sample collection is complete. The graphic on page 2 is optional, but may help put the project in context. 

Sample Registration

Sample registration is mandatory. Please walk your students through registration and double check to make sure every single sample you’re shipping is registered. Names must be matched with sample numbers. Families cannot check their results without their registration. This is a matter of public health. If parents are worried about maintaining privacy, contact

Collecting Samples

The protocol below can be sent home with the tubes, parent letter, and magnet. It explains how to collect a sample. 

Sample Tracking

Use this Excel sheet to keep track of who gets which sample number and if the sample is returned. This is very important for recording how many samples are run, where they come from, and helps if there is a missing registration. 

Shipping to Dartmouth

When you’re ready to ship your samples, let Anna ( know you’re preparing to ship and send her your sample tracking. She will send you the shipping address in return. Pack your samples as tightly as you can so they don’t roll around. You could put them in ziploc bags or stuff the remainder of your package with newsprint or bubble wrap. 

How to Check Results

Case Study Template

At the end of the project, you’ll write up a case study. Case studies will be posted on the website to help future teachers, will provide a record of the variety of curriculum and activities students took part in, and document the community meetings.
