Grade 6 – Biodiversity


The core of the Grade 6 program deals with introducing students to the concept of Biodiversity.

The following PowerPoint presentation will help you introduce the main concepts of Biodiversity to your students: Download Biodiversity Introduction .pptx Presentation


Biodiversity is short for biological diversity or simply – the variety of life on earth. The scientific definition of Biodiversity is as follows:

Biodiversity is the variability among living organisms from all sources, including inter alia [among other things], terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems.

It’s complicated, but there are two main points for you to take away from this definition: 1) The concept biodiversity is scale-able. It can refer to variety of life in terms of the variety of life within a species (think about how different all the students in your class are) all the way up to the diversity of ecosystems and bio-regions of life on the planet. Biodiversity can refer to the variety of:

  • genes within populations
  • populations within species
  • species within communities and ecosystems
  • ecosystems within landscapes
  • landscapes within bioregions
  • bioregions on the planet

2) Biodiversity is a key component of life on the planet.  Without biodiversity and the connections and relationships it creates, life systems fall apart. Biodiversity is critical to all life on the planet, including ours. It’s a big concept.  It’s also an important concept – students will need to not only understand what biodiversity is, but also understand why we need to protect it.  The Grow-A-Tree Program Biodiversity lesson plans focus on:

  1. Introducing the student to the concept of biodiversity though classification.
  2. Explaining why biodiversity is important.
  3. Examining threats to biodiversity.
  4. Demonstrating how students can help biodiversity in their own communities.

We are all part of the biodiversity on the planet, and biodiversity affects us in our everyday lives. We depend on the earth’s life systems to survive. Biodiversity is critical to supporting all life on Earth.  Biodiversity leads to healthy productive oceans and lakes, clean air to breathe and healthy soils for plants that all living things, including people, need to live and survive. Ultimately, habitat destruction leads to decrease in biodiversity that could potentially destroy our planet. Human activities are the major cause for the loss of biodiversity on the planet. There are many things that we can do and that are being done to help reduce our negative impact on ecosystems. One of the best things we can do help biodiversity is plant trees.  Trees form forests, the most bio-diverse ecosystems on the planet! At the end of this series of lessons, your students will get a chance to grow a tree and help biodiversity in their own community!
