Teaching Materials
Positives
- This resource details the ecosystem services of pollinators and decomposers, with a focus on mutualism.
- Each activity contains a helpful, quick assessment that teachers can perform to assess students' understanding.
- Students will love the hands-on activities, especially if they are able to get to know the soil outside.
Prerequisites
- For the first activity, students will need magnifying glasses, small trowels or spoons, shallow bins or trays, an outdoor soil patch or soil-filled container, and somewhere to record class findings.
- For the second activity, students will need cotton balls, paper cups or clothespins, paper flowers, and something to represent pollen.
- For the third activity, students will need clear 2-liter plastic bottles or clear jars, soil, food scraps, leaves or shredded paper, spray bottles with water, and labels.
Differentiation & Implementation
- Before going through the activities, teachers can spend a class period on the vocabulary terms. It may benefit students to have a word wall or flash cards to refer to throughout the lessons.
- Teachers may need to expand on some of the ideas touched on in the activities. For example, students may benefit from a more complete lesson (like this one) to understand the role of pollination in food production. Teachers may also need to explain the importance of healthy soil.
- These activities can be used to explain the connection between Sustainable Development Goal 2, Zero Hunger, and Sustainable Development Goal 15, Life on Land.
Key terms are clearly defined, and several additional resource links and videos are included. Three hands-on activities allow students to understand the role of species in an ecosystem that they may often just dismiss as ‘bugs’. This resource is recommended for teaching.
