🌱✨ The Amazing Journey of a Seed! การเดินทางสุดมหัศจรรย์ของเมล็ดพืช ✨🌱

Hello! สวัสดีค่ะ! This note is a summary of our science lesson about how plants grow. It follows our cool video script and the pages from our book. Let's review so you can be a science superstar! :-)

Key Points (ประเด็นสำคัญ)

• All plants grow, change, and have a life cycle (วัฏจักรชีวิต).
• The life cycle of most plants starts from a seed (เมล็ด).
• A seed needs soil (ดิน), water (น้ำ), and care to grow.
• The first part to grow from a seed is the root (ราก).

1. What is a Seed? (เมล็ดคืออะไรนะ?)

A seed is a very important part of a plant. It holds the baby plant inside! There are many different kinds of seeds. They have different properties (ลักษณะ) such as size, colour, and shape.

Table 1. Examples of Seeds (ตัวอย่างของเมล็ด)

Name of Seed	Picture from Book	Notes
Avocado	A large, round brown seed.	Very big!
Papaya (Pawpaw)	Small, round black seeds.	Many small seeds inside the fruit.
Watermelon	Flat, teardrop-shaped seeds.	Can be black or white.
Apple	Small, brown teardrop-shaped seeds.	Found in the core of the apple.

Note. Data adapted from science textbook (p. 24).

2. How Does a Seed Grow? (เมล็ดพืชเติบโตได้อย่างไร?)

When we plant a seed, it starts an amazing process called germination (การงอก). Let's look at the steps for our tomato seed!

Table 2. Stages of a Growing Seed (ขั้นตอนการเจริญเติบโตของเมล็ด)

Step (ขั้นตอน)	What Happens (เกิดอะไรขึ้น)	From the Book
1. Planting	We place the seed in the soil and give it water.	A tomato seed is placed on top of the soil.
2. Waiting	We wait for a few days. The magic is happening underground!	The seed is under the soil, getting ready to grow.
3. The Root Appears!	A white part comes out from the seed. This is the root (ราก). It grows downwards to find water.	A small white root starts to peek out of the seed.
4. Getting Bigger	The root grows longer and stronger.	The white root is now longer and more visible.

🤔 Question: What is the white part coming out from the seed? Answer: It's the root! (มันคือรากนั่นเอง!)

Note. Observations from "A growing seed under the ground" (p. 25).

3. Let's Plant! (มาปลูกต้นไม้กันเถอะ!)

You can be a scientist too! Just follow these easy steps from our book activity to plant your own tomato seeds.

1. Prepare (เตรียม): Get your tomato seeds, a flowerpot, and some soil.
2. Put soil in the flowerpot (ใส่ดิน): Fill your pot with soil.
3. Place seeds (วางเมล็ด): Put the seeds in the soil and cover them with a little more soil.
4. Continue to care (ดูแลต่อเนื่อง): Water your seeds and observe them every day. Let's see what happens! ☀️
