Teacher Resources


GSLI promotes science and environmental education of K–12 students and actively links the research sector with public outreach. We support field trips, summer camps, teacher training, and curriculum development centered on GSL. The goal of these activities is to develop critical thinking skills and inspire stewardship among the next generation. High school programs were supported by the Utah State Workforce Innovation in Regional Economic Development (WIRED) initiative, which is underwritten by the U.S. Department of Labor. GSLI serves to connect all of these parties in education and, ultimately, workforce opportunities regarding this unique lake.

Oolite Reactions Lab Instructions

Oolitic sand, the type of sand found on Great Salt Lake's beaches, is a unique geological component of the area. Oolitic sand is found only in a few locations around the world. It forms when minerals present in the water gather around a small particle in the water (often a brine shrimp fecal pellet). The large white beaches at Antelope Island, Spiral Jetty, and near the Great Saltair are all composed of oolitic sand. This lab will have students combine different substances with oolitic sand and determine whether or not a reaction has occurred.

Student Scaffold for Designing and Conducting Experiments

This document outlines a simple interactive method for designing and conducting experiements. Students get to interact with the document by filling in blanks, placing and replacing sticky notes, and drawing a graph. The structure of the document can help guide students through a broad variety of experimental contexts.

This game is designed to teach students about the magnification of toxic chemicals as they make their way through successive trophic levels. Students will each get assigned a type of organism at the beginning of the game and as the organisms interact (eat one another) toxic chemicals (colored chips) will be passed through the food web, accumulating at higher trophic levels.

Time required: 30–45 minutes

Bioaccumulation Game

Bioaccumulation Game Life Cards

Brine shrimp are an essential part of the Great Salt Lake ecosystem, and the commercial brine shrimp industry generates $40–60 million each year. In this activity, students experiment to determine the effect of abiotic factors on the hatch rates of this important organism.

Time required: 20–30 minutes to gather supplies, 90 minutes of class time for setup and design, 1–2 days to hatch brine shrimp.

In addition to completing the "Hatch-a-Cyst" activity, students may be interesting in seeing what brine shrimp look like in action. The Great Salt Lake Ecosystem program brochure provides step-by-step instructions for hatching brine shrimp in a miniature ecosystem. The brochure is also a great resource for extra information about brine shrimp and their life cycle.

This activity is an experiential way for students to learn about the challenges a pelican might face in their effort to migrate and breed each year. In this activity, students put themselves in the shoes of American White Pelicans living in the Great Salt Lake ecosystem. Students will have four "lives" as pelicans and will do their best to survive as they move to various locations (stations set up by the facilitator). Each location represents a real place a pelican might be found migrating, nesting, feeding, etc. At each location, students will learn about various environmental factors that affect pelican populations.

Wetlands Web Facilitation Guide

This activity, designed by the Tracy Aviary, is an experiential way to illustrate the connections between various parts of Utah's wetland ecostystems. Each student is assigned a living or nonliving thing that is a part of a wetland ecosystem. Students are then asked to make connections between one another, utilizing a string that gradually unravels from one organism to the next. At the end of the activity, the string connects all the organisms and the interdependence of the individuals becomes evident. View the full facilitation guide with more details for framing the activity and debriefing suggestions.

Time required: 30–45 minutes
