What is Saltwater Intrusion? K-6

Elementary

Description

The resource provides a hands-on activity through which students learn about the density of liquids, how saltwater and freshwater interact, and the actions that can be taken to prevent saltwater intrusion.

In the activity students carry out the simple procedure of  introducing saltwater (dyed blue with food coloring) into freshwater (dyed red) and recording their observations before answering a series of questions related to  saltwater intrusion.

This resource is part of a compilation of activities that enable teachers to integrate climate change research into their classrooms through fun, engaging and accessible learning experiences.

General Assessment

Recommendation of how and where to use it

This activity is best suited for the early elementary Science classroom.  Students can learn about the concept of density, how climate change can contribute to the problem of saltwater intrusion and how to prevent it.

The Discover Our Climate learning activities are designed for grades primary to six and focus on Atlantic Canada. Each activity encourages students to be curious and create solutions for the on-going climate challenges we face.
