Growing Our Own Plants

Hands-on experience planting seeds and observing their growth over time.

About This Topic

Growing Our Own Plants gives Year 1 students direct experience with seed germination and plant development. They follow steps like filling pots with compost, pushing seeds in to the correct depth, watering carefully, and positioning in sunlight. Over weeks, children observe roots pushing down, shoots emerging, and true leaves forming. They record these changes with drawings and simple tables, linking to KS1 standards on plants' requirements for life.

This unit builds core scientific practices: making predictions about growth without water, fair testing conditions, and communicating findings. It connects to maths through height measurements and the wider curriculum via seasonal changes in the Plant Detectives unit. Students learn plants need light, water, and nutrients from soil, fostering responsibility and environmental awareness.

Active learning excels in this topic because children witness gradual transformations from their daily care, which strengthens memory and motivation. Group predictions and shared observations reveal patterns, while hands-on adjustments to variables like watering clarify cause and effect.

Key Questions

1. Explain the steps involved in planting a seed.
2. Observe and record the changes in a growing plant over several weeks.
3. Predict what might happen if a planted seed does not get enough water.

Learning Objectives

• Identify the essential components required for a seed to germinate and grow.
• Record and describe the observable changes in a plant's structure over a period of several weeks.
• Predict the impact of insufficient water on a plant's growth and survival.
• Explain the sequence of actions needed to successfully plant a seed.

Before You Start

Living and Non-Living Things

Why: Students need to be able to distinguish between living organisms and inanimate objects to understand that plants are living things that grow.

Basic Needs of Living Things

Why: Understanding that living things need food, water, and air is foundational to grasping the specific needs of plants for growth.

Key Vocabulary

seed	A small structure that contains a young plant and stored food, capable of growing into a new plant.
germination	The process where a seed begins to sprout and grow into a young plant, typically when conditions are right.
roots	The part of a plant that typically grows underground, anchoring the plant and absorbing water and nutrients from the soil.
shoot	The part of a plant that grows upwards from the seed, which will develop into the stem and leaves.
compost	Decayed organic material used as a plant fertilizer, providing nutrients for growth.

Watch Out for These Misconceptions

Common Misconception

Plants grow without water.

What to Teach Instead

Many children think plants can survive like animals without drinking. Planting paired seeds, one watered and one dry, lets them observe wilting and no growth directly. Group comparisons correct this through evidence.

Common Misconception

Seeds are not alive until they sprout.

What to Teach Instead

Students often see seeds as inert objects. Dissecting sprouted versus dry seeds under magnifiers shows early root tips, proving life from the start. Hands-on exploration shifts views via visible proof.

Common Misconception

Plants eat the soil they grow in.

What to Teach Instead

Children believe plants consume soil to grow bigger. Measuring soil before and after growth, paired with massing plants, shows soil weight stays similar. Experiments clarify nutrients dissolve in water.

Active Learning Ideas

Whole Class: Seed Planting Demonstration

Model the planting process on the interactive whiteboard, then have each child plant their own bean seed in a clear pot. Label pots with names and place on a sunny windowsill. Instruct daily checks for watering and recording.

Small Groups: Growth Observation Stations

Set up stations with magnifying glasses, rulers, and journals. Groups rotate to measure, draw, and describe one plant feature like stem height or leaf number. Discuss changes as a class after rotations.

35 min·Small Groups

Pairs: Water Prediction Experiment

Pairs plant identical seeds: one watered daily, one not. Predict outcomes on charts, observe weekly, and compare results. Guide discussions on why water matters.

40 min·Pairs

Individual: Plant Growth Journals

Each child maintains a weekly journal with dated drawings, height marks, and notes on changes. Review journals mid-unit to predict next stages.

Real-World Connections

• Horticulturists at botanical gardens, like Kew Gardens in London, use their knowledge of plant needs to cultivate and conserve a wide variety of plant species from around the world.
• Farmers carefully plant seeds in fields, ensuring they receive the correct amount of water and sunlight to grow crops that will feed communities.
• Home gardeners select seeds and soil to grow vegetables and flowers in their own gardens, experiencing the satisfaction of nurturing plants from seed to harvest.

Assessment Ideas

Quick Check

Show students a picture of a seed and ask: 'What three things does this seed need to start growing?' Record their answers on the board. Then, show a picture of a wilting plant and ask: 'What might be missing for this plant?'

Discussion Prompt

Gather students around their planted seeds. Ask: 'Look at your plant today. What changes do you see from last week? What do you think will happen next week if we give it plenty of water and sunlight?' Encourage them to use vocabulary like 'shoot' and 'roots'.

Exit Ticket

Give each student a small piece of paper. Ask them to draw one step involved in planting a seed and write one word to describe what the plant needs to grow.

Frequently Asked Questions

What basic needs do plants require in Year 1?

Plants need light for energy, water for transport, air for respiration, and nutrients from soil. Lessons focus on observing effects of missing water or light through simple tests. Children record healthy versus unhealthy plants, building understanding of conditions for growth over weeks.

How can I teach children to record plant observations accurately?

Provide templates with spaces for drawings, labels, dates, and measurements. Model descriptive words like 'taller' or 'green leaves'. Daily 5-minute sessions build habits, with peer sharing to refine skills and spot patterns in class data.

How does active learning support plant growth lessons?

Active approaches like personal planting and daily tending create ownership, as children link their care to visible changes. Experiments testing variables, such as light or water, engage prediction and evidence evaluation. Collaborative journals and discussions deepen retention over passive lessons.

What if seeds do not germinate in class?

Use fast-sprouting beans or peas, ensure fresh seeds and moist compost. If issues arise, discuss variables like temperature openly. Replace with cress for quicker results, turning setbacks into fair testing lessons on plant needs.
