This development stage is crafted for students to actively apply and deepen their existing knowledge of the Plant Kingdom. Through fun and challenging activities, they will delve into plant classification and their interactions within ecosystems, solidifying their understanding in a dynamic and relevant manner.

Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - The Plant Classification Challenge

> Duration: (60 - 70 minutes)

- Objective: Enhance the skill of taxonomic classification of plants and comprehension of the morphological features that distinguish them.

- Description: In this activity, students will embark on classifying a series of plants based on their morphological and functional features. Images of various plants will be shown, and students, working in groups, will use cards with names of plant subgroups (angiosperms, gymnosperms, pteridophytes, bryophytes) to classify them accurately.

- Instructions:

• Divide the class into groups of up to 5 students.

• Provide each group with a set of cards representing the main subgroups of plants.

• Display slides with images of different plants and ask the students to classify each one using the cards.

• Each group must justify their classification, explaining the characteristics they noted about the plants.

• Wrap up by discussing the classifications with the entire class, addressing and clarifying doubts.

Activity 2 - Ecosystem Builders

> Duration: (60 - 70 minutes)

- Objective: Understand the interactions between plants and other organisms in an ecosystem while appreciating the significance of biodiversity.

- Description: Students will work in groups to design and construct small ecosystems in transparent containers, utilizing various types of plants. The objective is to create a balanced ecosystem that can support small creatures, like insects and arachnids, which will be introduced later.

- Instructions:

• Organize students into groups of up to 5.

• Distribute transparent boxes, soil, stones, small plants, and decorative items to each group.

• Supervise the groups as they plan and assemble their ecosystem, accounting for the water, light, and space needs of each plant.

• After assembly, introduce small animals to the ecosystem and observe its functioning over a few days.

• Each group presents their ecosystem, explaining the chosen plants and their roles in maintaining balance.

Activity 3 - Journey to the World of Plants

> Duration: (60 - 70 minutes)

- Objective: Foster understanding of how plants adapt to varying environments and reinforce knowledge about plant diversity.

- Description: In this engaging activity, students act as 'explorers' planning an expedition to gather plants from different biomes. Each group will be assigned a biome and, through brief research, will plan a route and compile a list of plants they wish to discover.

- Instructions:

• Divide the classroom into groups of up to 5 students.

• Assign each group a different biome (such as tropical rainforest, desert, tundra, etc.).

• Guide the students to quickly research their assigned biome, its features, and the typical plants found there.

• Based on their findings, groups should outline an expedition route and list the plants they aim to collect.

• Each group presents its expedition plan, justifying their choices and discussing how the plants adapt to their biome.

Feedback
