Minds-On: What does “healthy” mean? (10 min.)
Instructions | Teaching Tips |
---|---|
Have a discussion with students about what the word “healthy” means. You could start with a general sharing and then direct students to consider contexts in which the word “healthy” is used. Record student ideas on chart paper. By the end of this activity, students should understand that health means a state of well-being. Healthy plants and animals are able to undergo normal functions in their life cycles. Healthy environments have a minimum of things that can harm living things, such as pollution, radiation and disease-causing organisms. |
DiscussionsDiscussion prompts can include:

Action: Is this soil healthy? (15 min.)
Instructions | Teaching Tips |
---|---|
Show students the Healthy Soil slideshow [Google slides] [pptx] [PDF]. In it they will learn about what defines “healthy” soil. Image - Text VersionShown is a colour illustration of a small green plant growing up from the centre of a patch of brown soil.
They will also look at images and determine whether they think the soil in the image is healthy or not. Finally they will learn what people can do both to harm and protect soil. |
DiscussionsAnimations are provided with each slide so that students can share their ideas before seeing further text. Additional questions and information are also found in the presenter notes. Images and VideosFor students who have visual impairments, use the descriptions provided in the alt text to describe the images. |
Consolidation: 3-2-1 Soils! (20 - 30 min.)
Instructions | Teaching Tips |
---|---|
Use a 3-2-1 Learning strategy to have students consolidate their learning around the characteristics of soil and soil health. Students could do this on a piece of paper, in a science journal, or on the 3-2-1 Soils! reproducible [Google doc] [Word doc] [PDF] |
LanguageMake sure students have access to a word wall of terminology used in this lesson such as soil, organic matter, nutrient, water, compost, plant, healthy, roots, etc. Incorporate vocabulary in other relevant languages as well (e.g., French). |
Background Information for Teachers
Healthy Soils
Image - Text Version
Shown is a colour photograph of a cross-section of grass with roots growing down into soil.
A strip of green grass stretches across the top of the photograph. Below, most of the photograph shows its roots in the soil. They are thin, white and squiggly, tangled together like hair. All the roots are growing downward, deeper into the soil.
Image - Text Version
Shown is a close-up colour photograph of ants on pale brown soil with a small hole in the centre.
The camera looks straight down on pale, grainy soil that looks like sand. Several dry leaves and twigs lie across the surface. There is a small deep hole in the centre of the image. Black ants crawl over and around the soil and vegetation, and down into the hole.
