Comparing Habitats: Observing the Diversity of Living Things
Grade 2 · Science · NYSSLS 2-LS4-1 · 50 Minutes
NYS-Aligned Standard
2-LS4-1 — Make observations of plants and animals to compare the diversity of life in different habitats. NYS P-12 Science Learning Standards / NYSSLS (2017)
Three Dimensions Engaged:
- Science & Engineering Practice: Planning and carrying out investigations (making observations)
- Disciplinary Core Idea: LS4.D — Biodiversity and Humans
- Crosscutting Concept: Patterns
Learning Objectives — “I Can” Statements
- I can make careful observations of living things in a habitat.
- I can compare the plants and animals found in two different habitats.
- I can explain that different habitats are home to different kinds of living things.
Essential Question
Why do we find different plants and animals living in different places?
Lesson Sequence
Hook / Warm-Up (8 min)
Show paired photos of two habitats (a pond and a forest). Ask: “What living things do you see in each? Are they the same or different?” Record student noticings on a two-column chart.
Direct Instruction (10 min)
- Define habitat: the place where a plant or animal lives and gets what it needs (food, water, shelter, space).
- Define diversity: the many different kinds of living things.
- Model a careful observation using an observation sentence: “I observe a ___. It has ___.”
Guided Practice (15 min)
Using habitat picture cards (pond, forest, desert, meadow), small groups list the plants and animals they observe in each. Groups complete a habitat comparison chart: Which living things are in BOTH? Which are in only ONE?
Independent Practice (12 min)
Each student picks two habitats and draws/labels two living things in each. They complete the sentence frame: “A ___ lives in the ___ habitat because it can find ___ there.”
Closure (5 min)
Share out: “Name one living thing that lives in a forest but NOT in a pond. Why?”
SDI & Differentiation Block
Supports for MLLs/ELLs
Entering/Emerging (NYSESLAT Levels 1–2):
- Picture-word cards for each habitat and organism (pond/frog, forest/deer)
- Sentence frame: “I see a ___ in the ___.”
- Allow sorting organism cards into habitat bins instead of writing
Transitioning/Expanding (NYSESLAT Levels 3–4):
- Vocabulary: habitat, diversity, observe, compare, shelter
- Sentence frame: “A ___ lives in the ___ because ___.”
Supports for Students with IEPs
SDI Adaptation Dimensions: content, methodology, delivery
- Content: Compare two habitats instead of four; pre-select organism cards
- Methodology: Hands-on card sort; use real classroom plants or a window observation
- Delivery: Read all prompts aloud; allow verbal or drawn responses; extended time
Suggested Placement: ICT, Resource Room
Model Response
Pond vs. forest: “A frog lives in the pond habitat because it can find water and insects there. A deer lives in the forest habitat because it can find plants to eat and trees for shelter. Both habitats have living things, but they are different kinds.”
