Prepared by: Teacher Le Quoc Chon

Subject: Science for Primary School

Grade Level: 3^rd Grade

Approximate Time Needed: 30 – 45 minutes

Summary: The purpose of this lesson is to help students learn the basic concept of plant life cycle, to read and understand the life cycle diagram. We use Jalapeno Pepper as an example. Students learn through working in groups and using materials and resources for hands-on activities.

Essential questions:

What is a life cycle? Of animals and of plants?

How does a seed grow into a plant?

What are the needs for a seed to grow?

What are the main parts of a plant?

What are the 4 stages in the life cycle of Jalapeno Pepper?

What are the differences between adult plant and young plant?

Can you grow a plant?

How to take care of the plant?

Key words to remember and understand:

Life cycle

Stages: seed, seedling, young plant and adult plant

Seed coat, Germination, Nutrients

Life cycle of Jalapeno Pepper

Definition: A life cycle is the stages of development and growth that living things go through.

There are 4 stages in the life cycle of Jalapeno Pepper: seed, seedling, young plant and adult plant.

Seed

All plants go through a life cycle which is the changes happen to a living thing. And most plants start as seeds. The seed sucks in water, and gets bigger and bigger over times. This is called germination. Seeds need water, warmth, sunlight and soil to grow.

Seedling

Next, a little root grows into the soil and a sprout grows into the air. The sprout takes in sunlight, nutrients, and water. At this stage, it is called a seedling. Seedling has a few small leaves.

Young plant

The seedling grows into a young plant. The roots go down deep into the soil searing for water and nutrients. The stem becomes stronger and thicker. The leaves get bigger.

Adult plant

A plant is called an adult when it stops growing. At this stage, it grows flowers and the flowers have small seeds inside them. The seeds will grow and ready to start new life cycle again.

Write the words: seed, seedling, young plant and adult plant into the boxes in the following diagram.

Main parts of a plant: root, stem, leaf, flower and fruit.
