Needs of Living Things

First graders learn best when they can touch, observe, and test ideas for themselves. This topic about living things' needs comes alive when students plant seeds, sort pictures, and talk through what happens when a need is missing. Active learning helps children move from vague ideas like 'plants need things' to clear patterns like 'all plants need sunlight.'

Learning Objectives

1. Identify the four basic needs of plants and animals for survival: food, water, air, and shelter.
2. Compare how different plants and animals obtain their essential needs from their environment.
3. Explain what might happen to a plant or animal if one of its basic needs is not met.
4. Classify living things based on how they meet their need for food.

Investigation: What Does a Plant Need?

Set up four bean seedlings in different conditions: one with full needs met, one without light (covered box), one without water, and one without soil (roots suspended in air). Students observe all four over one week, sketch changes daily, and present their findings on a simple class chart showing which plant thrived and why.

Prepare & details

Explain the essential needs for a plant to grow and thrive.

Facilitation Tip: During Investigation: What Does a Plant Need?, place identical bean seeds in clear cups so students can watch root growth and leaf color changes over time.

Sorting Activity: Animals and Their Needs

Give each group a set of animal picture cards and three sorting mats labeled 'Food', 'Water', and 'Shelter'. Students sort images showing each animal meeting each need, then discuss: do all animals need all three? The class compares sorts and identifies one animal whose way of meeting each need is surprising or unique.

Prepare & details

Compare the basic needs of different animals.

Facilitation Tip: During Sorting Activity: Animals and Their Needs, provide a mix of picture cards so students must justify choices rather than rely on obvious pairings.

Think-Pair-Share

⏱ 20 min·Pairs

Think-Pair-Share: What Would Happen?

Present three scenarios one at a time: a pond dries up, a forest is cleared, a field has no insects. For each, students predict which animals or plants are affected and why. Pairs share their reasoning before the class builds a web of connections showing how the absence of one resource affects many organisms.

Prepare & details

Predict what would happen to an animal if one of its basic needs was not met.

Facilitation Tip: During Think-Pair-Share: What Would Happen?, set a timer so children practice concise responses and peer listening.

Setup: Standard classroom seating; students turn to a neighbor

Teaching This Topic

Start with concrete examples before abstract rules. Use living plants or seeds in class so students experience growth firsthand. Avoid rushing to vocabulary like 'photosynthesis'; instead, help children notice that green leaves and sunlight seem connected. Research shows first graders grasp survival needs when they observe immediate effects, so keep cycles short—one week for plant growth observations is plenty.

What to Expect

By the end of these activities, students will identify the four basic needs of living things, explain how plants and animals meet those needs differently, and predict consequences when a need is not met. You will see clear evidence in their labeled drawings, sorting choices, and discussion comments.

Watch Out for These Misconceptions

Common Misconception

During Investigation: What Does a Plant Need?, watch for students saying plants do not need food because they are not animals.

What to Teach Instead

Prompt students to compare a seedling in sunlight to one in darkness; ask what they notice about leaf color and stem strength after three days, then guide them to see that the plant uses sunlight and water to make its own food.

Common Misconception

During Sorting Activity: Animals and Their Needs, watch for students limiting 'shelter' to nests or houses.

What to Teach Instead

Provide picture cards of a beetle under bark, an aphid on a leaf underside, and a lizard burrowed in sand, then ask students to sort these under the heading 'shelter' to expand their definition.

Assessment Ideas

Quick Check

After Sorting Activity: Animals and Their Needs, provide picture cards and ask students to sort into groups based on one shared need. Listen for correct vocabulary and grouping logic during the class discussion.

Exit Ticket

During Investigation: What Does a Plant Need?, hand each student a half-sheet to draw one plant or animal, label the four needs, and write one sentence about what would happen if one need was missing.

Discussion Prompt

After Think-Pair-Share: What Would Happen?, pose the scenario 'a bird loses its nest' and ask students to list immediate problems. Listen for connections between shelter and protection from weather or predators.

Extensions & Scaffolding

• Challenge: Ask students to design a creature that lives on a sunny desert island and list its needs. Have partners guess which habitat fits their creature.
• Scaffolding: Provide sentence stems on sentence strips for the Think-Pair-Share: 'If a rabbit lost its shelter, first it would be cold because...'
• Deeper: Bring in a terrarium or aquarium. Ask students to map which living things in the habitat provide shelter for others.

Key Vocabulary

Needs	Things that all living things require to survive and grow, such as food, water, air, and shelter.
Shelter	A place that provides protection and safety from weather and predators for plants and animals.
Photosynthesis	The process plants use to make their own food using sunlight, water, and air.
Habitat	The natural home or environment where a plant or animal lives, providing the things it needs to survive.
