Introduction
Topic: The Life cycle of Plants
Purpose: In the process of seed maturity, they are more interested in plants on Earth and make them feel attractive. This webquest focuses on plants grow, reproduce. In fourth grade science, we learn the life cycle of plants, so in connection with this, not only the growth of plants as scientific knowledge but understanding the life cycle of plants is crucial. Also appreciating their role.
Task
From now on, you are a little botanist. And you have to accomplish your task.
Through planting and growing the seeds(Kidney beans) yourselves, you will research the stage of the life cycle of plants and find out the necessary conditions for seeds to sprout. After these, you can compare the life cycle of various plants.
This project identify the characteristics and importance of the stages in which plants grow.
Process
Day 1.
Objective: Let's make a plan to observe the life cycle of a plant and plant seeds.
● Activity 1 Choose a plant to Observe
- To observe the life cycle of plant, Think about what condition it would be best to select a plant.
[Thinking Tip] Between chestnuts and kidney beans, which plant is easier to observe in its life cycle? Why do you think so?
● Activity 2. Plan to observe the life cycle of plants
- Think about how long you will observe, what you will observe, and how you will observe it.
● Activity 3. Plan to Plant Seeds
- Think about when, where, and how to plant plant seeds.
● Activity 4. Write an observation plan
- Write an observation plan based on step 2 and step 3 in your worksheet.
Day 2.
Objective: Let's find out the conditions necessary for seeds to sprout.
● Activity 1. Find out if seeds need water to germinate

● Activity 2. Find out if temperature affects on seed germinate
- https://www.bing.com/videos/riverview/relatedvideo?q=the%20conditions%20necessary%20for%20seeds%20to%20sprout.&mid=98A3D49116B2D266265098A3D49116B2D2662650&ajaxhist=0 This video will explain how temperature affects seed sprouting.
● Activity 3. Planting seeds
- Plant seeds and observe according to the observation plan. and try to germinate the seeds by considering the conditions for them to germinate.
Day 3.
Objective: Let's observe the process of seeds sprouting.
● Activity 1. Comparing kidney beans before and after sprouting
- Supplies: Unwatered kidney beans, sprouted kidney beans with water, magnifying glass
- Organizing how kidney beans differ before and after sprouting.
● Activity 2. Observing the process of sprouting
- Watching the video to observe the process of kidney bean sprouting and describe it in writing.
● Activity 3. Drawing of the process of seeds sprouting
- hard seeds
- Swelling seeds
- Seeds that sprout roots
- The skin peels off and two seed leaves(cotyledons) emerge.
- Leaves emerge between the seed leaves(cotyledons).
- Seed leaves(cotyledons) wither up and leaves grow larger.
Day 4.
Objective: Let's observe changes in the flowers and fruits of plants.
● Activity 1 Observing the flowers and fruits of the kidney beans and show them in writing or pictures.
- supplies: Video, a flowerpot that has begun to bloom - just observe with your eyes - writing and drawing on your 'observation diary'
● Activity 2. Observing where kidney beans produce their fruits. - observe with your eyes -Through video, you can check ithttps://youtu.be/hCuXNmsNNac?si=8PhqbbHYDFihEnaQ
● ACtivity 3. Opening the pods to observe the seeds. - The fruit where the kidney bean flowers grow is called a pod. - The kidney beans in the pod are actually the seeds of kidney beans.https://youtube.com/shorts/E0GFDBW2T8s?si=s-IGaT4yc-BbKBds
Day 5.
objective: Let’s compare the life cycle of various plants.
Activity 1. find out the annual plants
- watching the video to observe the life cycle of corn
https://www.youtube.com/watch?v=RW_GpNciIuA
- analyzing the life cycle of corn
- investigating a variety of annual plants
Activity 2. find out the perennial plants
- watching the video to observe the life cycle of apple tree
https://www.youtube.com/watch?v=eBzTCbGnlWo
- analyzing the life cycle of apple tree
- investigating a variety of perennial plants
Activity 3. compare the life cycle of annual and perennial plants
- explaining the commonalities between annual and perennial plants
- explaining the differences between annual and perennial plants

Conclusion
Great job! You've accomplished your task!!
From your task, you've learned all about the life cycle of plants, from tiny seeds to fully grown plants.
You now know what it takes for a plant to grow and you know what each stage of a one-year-old has.
You have to keep exploring the various plants around you! because you are a little botanist!!
