Diversity of Life in Different Habitats – 2nd Grade Science Unit

This Diversity of Life Unit will keep your students engaged and save yourself time with this unit covering the diversity of life in different habitats! Students love my activites on diversity of life in different habitats.

Students will think about how life in desert habitats is different than life in the tropical rainforest or on the tundra. Animals and plants have special adaptations that allow them to live in these special habitats. Students will classify animals but the type and learn the characteristics of different animals such as amphibians, reptiles, mammals, birds, fish, and arthropods.


Your 2nd-grade science class will LOVE this low-prep complete unit. Students love these sorting activities.

biodiversity for second grade

This engaging unit on diveristy of life in different habitats is designed to teach the NGSS standards for 2nd grade on biodiversity. Would you like to know a little more about Biodiversity?

It will help you cover NGSS 2-LS4-1 as well as Utah SEEd 2.2.1!

Make observations of plants and animals to compare the diversity of life in different habitats.

NGSS 2-LS4-1

Obtain, evaluate, and communicate information about patterns of living things (plants and animals, including humans) in different habitats. Emphasize the diversity of living things in land and water habitats. Examples of patterns in habitats could include descriptions of temperature or precipitation and the types of plants and animals found on land habitats.

Utah SEEd 2.2.1
the desert habitat

This large unit on biodiversity includes a variety of activities!

It has a PowerPoint slide show on biodiversity and classes of animals, non-fiction articles, a layered flipbook, data recording pages, response pages, 64 animal cards, two task cards, and answer keys for everything!

biodiversity flip book

In this complete unit, students will see a slideshow on biodiversity and classes of animals. They will read nonfiction articles provided. They will record data, create a layered book, answer response pages and they will sort animals by habitat and class: mammals, birds, fish, reptiles, amphibians, arachnids, and insects.

diversity of life

Students will learn about the classification of animals and about the distribution of organisms across our planet. They will learn that some places on Earth have higher biodiversity than others. They will also learn that animals have adaptations that help them survive in their habitat. They will learn that there is a wide variety of animals and plants leaving in each habitat and that animals are adapted to survive in their habitat. Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. While Earth’s biodiversity is so rich that many species have yet to be discovered, many species are being threatened with extinction due to human activities, putting the Earth’s magnificent biodiversity at risk. 

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.
