Life Cycle of Plants
Activity Duration: 1-1.5 months - Day 1 - 45 minutes, Days 2-45 - 10 minutes each day.
Guiding Question: What is the question to explore OR the problem or challenge to solve?
What are the basic needs of plants and how to plants grow?
Youths will investigate the life cycle of plants by growing vegetables in containers to observe the different stages of a plant’s life cycle.
Through this activity, youth will:
Investigate what conditions provide the best conditions for a plant to grow
Observe and record observations each week what their plant looks and taking measurements.
Share and communicate the data they have collected with the large group.
Draw conclusions and relationships between the conditions their plant was under and how they compared with the conditions of the others.

Preparación
Facilitator prep:
Facilitators will need to grow a radish plant prior to this activity to create a control plant. While this plant is growing, facilitators need to measure how much and how often the plant receives water, how many hours of sunlight the plant receives, the air temperature each day and the type of soil the plant receives. Students will use this data to test and compare plants they grow.
A plant is a living system. Just like animals, plants have basic needs in order to survive. A plant’s basic needs are: sunlight, air, water, nutrients, and space in the amount suitable to that plant.
Animals get their energy from the food they consume. Green plants get their energy from the sun. The process is called photosynthesis. Sunlight activates the chlorophyll in leaves to convert raw materials from soil and air into carbohydrates (starches and sugars), which are the plant’s food.
Just like animals, water is important to plants because it is a primary component of the material that makes up the plant’s structure. Just like in animals, water is what helps give cells their shape. Water also helps transport nutrients from the soil to the plant’s roots.
Plants need a growing medium (such as soil) for support and to provide nutrients (raw materials to make food). Most plants need soil. The type of soil necessary to sustain a plant depends on characteristics such as: texture (compact or porous), water-holding capacity, acidity, and population of beneficial soil organisms.
Plants also need space to grow. If they do not have enough space and if they must compete with neighboring plants for nutrients, light and water, plants may find it difficult to grow or survive.

Room: Day 1 of this activity can take place indoors or outdoors. If indoors, youth will need tables to work on or trays to contain messes if working on the floor. Having a substrate table with bags or buckets of growing medium will be helpful so children can help themselves. There will need to be a pre-determined location for plants to be stored throughout the month that is easily accessible so students can make observations each day.

Inquiry: Your primary goal as facilitator is to encourage youth to explore and observe the life cycle of plants. You can prompt those discussions with questions like the following:
What variable are you changing?
How do you think this will affect your plant?
Do you think it will grow better or worse?
Facilitator Checklist for Preparation:
Organization: I practiced the activity/technology, prepared materials/extras/place to record youth ideas, completed an activity (including timings).
Materials: Materials are appropriate for teaching the learning goals; youth will be able to use them and will think they are appealing.
Space Utilization: The space is set up appropriately for the activity and there will be no safety issues or distractions.
Relevance: I have researched why the content matters to youth’s everyday lives.
Content Learning: I have become familiar with the content.
Inquiry: I have become familiar with how authentic, age-appropriate inquiry practices look in this activity.
Introducción a la actividad
(10 MINUTES)
Have children sit in a circle and read the book: Oh Say Can You Seed? By Bonnie Worth.
Discuss with the youth what plants need to grow: sunlight, air, water, nutrients, and space in the amount suitable to that plant.
Facilitator Checklist for Introduction to Activity:
Space Utilization: I will use the space informally avoiding the lecture hall format.
Purposeful Activities: This intro section gets youth on track for the learning goal.
Content Learning: If age appropriate, I will accurately present content.
Inquiry: In this or another section of the activity, youth carry out one or more inquiry practices.
Relationships: I will make each youth feel welcome.
Relevance: In this or another section, I will guide the youth in a sustained discussion of how the activity relates to their everyday lives.
Youth Voice: In this or another section, I will allow youth the opportunity to make decisions about their learning experiences.
Compromiso con la actividad
(25 MINUTES)
Explain in a large group that each youth is going to grow and observe radish plants. Youth will work in groups of 2. In their groups, youth will decide what variable they would like to test (soil type, light amount, water amount or temperature). Each group will grow 2 plants; one plant will be their control plant using the variables set up by the facilitator’s plant. The other plant they will change one of the variables to see how it effects their plant. After planting their seeds, they will record daily observations and measurements (once plants have sprouted).
Facilitator Checklist for Activity Engagement:
Space Utilization: I will use the space informally avoiding the lecture hall format.
Participation: All youth will have access to the activity.
Purposeful Activities: This core section helps youth to move toward the learning goal.
Engagement: This activity has youth physically engaged with their hands and their minds.
Inquiry: In this or another section of the activity, youth carry out one or more inquiry practices.
Reflection: If appropriate, I will ask youth questions during the core activity that will help them make sense of what they are learning.
Relationships: I will take steps to share my enthusiasm and create a nurturing, safe learning environment.
Relevance: In this or another section, I will guide the youth in a sustained discussion of how the activity relates to their everyday lives.
Youth Voice: In this or another section, I will allow youth the opportunity to make decisions about their learning experiences.
Reflexión final y relevancia
(5 MINUTES)
On the final day, youth should come together as a large group to share the results of their experiments.
What variable did you test?
Which plant grew better?
To help youth connect this lesson with their real lives, prompt discussion with these questions.
Has anyone ever planted a garden? Tell us about it.
What do you notice about plants in the winter? The summer?
Can you think of any fruits or vegetables that you eat that have seeds?
