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.'

Activity 01

• Progettazione (Reggio Investigation)
• 15 min · Small Groups

Progettazione (Reggio 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.

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.

What to look for

Provide students with picture cards of various plants and animals. Ask them to sort the cards into groups based on one need they share (e.g., animals that need trees for shelter, plants that need sunlight). Discuss their groupings as a class.

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.

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.

What to look for

On a half-sheet of paper, ask students to draw one plant or animal and label the four basic needs it requires to survive. Then, ask them to write one sentence explaining what would happen if one of those needs was not met.

Activity 03

• 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.

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.

What to look for

Pose the question: 'Imagine a bird loses its nest. What are the immediate problems it might face because it lost its shelter?' Guide students to connect the loss of shelter to other needs, like protection from weather or predators.

A few notes on teaching this unit

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.

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

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

  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.

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

  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.
