This is a list of the posts that provide suggestions about the nuts and bolts of using CTTM in your classroom. The following posts describe how to set up Building IDs, obtain permission to collect samples, collect the data, and more.
Every student participating in CTTM needs an “Observer ID.” The Observer ID keeps students’ identities private while still allowing teachers to connect students with their work. This post describes how to create Observer IDs.
Students have the option of comparing the quality of water from more than one tap in a building. This might be especially interesting if some taps are filtered and others are not. This post shows how to add a tap.
Crowd the Tap considers how the entire delivery system from water supply to tap might affect water quality. The building in which the tap is located is a key element in that system. This post describes the information that students collect about individual buildings.
Students need written permission from parents, guardians and other adults to collect water samples from homes and other privately owned buildings. This post includes a link to the permission form that students should use. It also explains why it is important to get permission and communicate the goals of the project before collecting samples.
Students collect CTTM data about buildings, taps, water chemistry and water quality using paper worksheets. They use different dataheets for different kinds of data. This post explains how the different datasheets relate to each other and will help teachers in organizing and overseeing the students’ work as they enter data.
Maine is a rural state. Rather than having a few big city water systems, Mainers get their water from many small and mid-sized public systems in addition to private wells. In this post we provide information about the different kinds of public water systems that students will need as they map drinking water quality.
Crowd the Tap Maine builds a picture of water quality in an area by collecting samples from many different “taps,” or faucets. By collecting samples from many different taps, we can build a picture of what is happening in a water system. This post describes how collect information about a single tap.
