Contextualization

Cytology, or Cell Biology, is the field of Biology that studies cells in relation to their structures, functions, their interactions, how they work alone or in community. It is the basis of vital functions, being essential to understand how living beings work.

Since the first observation of a cell in the 17th century, cytology has evolved with the technological revolution. Advances in microscopy and laboratory techniques have expanded our understanding of cells, allowing scientists to visualize cells and cell structures in ever-greater detail.

Introduction

Cells are the smallest living unit of life that can carry out all the functions necessary for life. They are like building blocks for plants and animals. They are called "cells" because Robert Hooke, who discovered them in 1665, thought they looked like the small rooms that monks lived in (called cells).

There are two main types of cells: prokaryotic cells, which do not have a defined nucleus and are usually unicellular, such as bacteria; and eukaryotic cells, which have a defined nucleus containing the genetic material and can be unicellular or multicellular, such as humans.

Cells are made up of various organelles, which are like small organs. Each organelle has a specific function that helps the cell to function properly. Some of the most important organelles include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes.

Hands-on Activity: "Exploring Cellville"

Project Goal

This project aims to investigate the structure of eukaryotic cells and their organelles in a playful, detailed, and comprehensive way. Students will create a three-dimensional model of a eukaryotic cell, as well as present the functioning of each organelle in an explanatory video.

Detailed Project Description

In this project, students will work in groups of 3 to 5 people. Each group must choose a type of eukaryotic cell to study. Students will be tasked with researching the chosen cell extensively, learning about the function of its organelles, and creating a detailed physical model representing the cell and its parts.

In addition to creating the model, groups must produce a short video (5 to 10 minutes) where they present their cell and explain its components, and what each component does. If possible, the video should show the process of assembling the model.

Required Materials

• Recyclable materials, such as cardboard, plastic, etc.
• Paint, markers, or other coloring materials.
• Glue.
• Scissors.
• Cell phone or camera.
• Internet access for research.

Detailed Step-by-Step Guide for the Activity

1. Form groups of 3 to 5 students.
2. Each group must choose a type of eukaryotic cell to investigate.
3. Students should research details of the chosen cell, including the size, shape, and position of the organelles.
4. Based on the research, plan and build the physical model, trying to represent the cell and its parts as faithfully as possible.
5. Record a video showing the model and explaining what each part does.
6. In the video, also include the model's assembly process.
7. Review the final video and make edits if necessary.
8. After the project is completed, the groups should present their videos in the classroom.

Project Deliverables and Activity Connections

Groups must deliver:

1. The physical model of the eukaryotic cell.
2. The explanatory video of the model and the functions of the organelles (upload to Google Drive or YouTube).
3. A report detailing the model construction process, the information gathered during the research, and a reflection on what they learned during the project.

The report should contain four main sections:

1. Introduction: Explains the reason for choosing the type of cell, introduces the topic of cytology, and contextualizes the relevance of the project.
2. Development: Describes the research and model construction process, details the functions of each organelle, and discusses how the model portrays the cell.
3. Conclusions: Highlights the main learnings obtained during the project and reflects on the importance of studying cytology.
4. Bibliography: Lists the sources of information used in the project.

The report must be submitted in digital format, using Google Docs or Microsoft Word. The report's writing should be clear, well-organized, and detailed, and should demonstrate the group's understanding of the topic.

In addition, students should be able to demonstrate technical skills, such as interpreting texts and understanding cytological concepts, as well as socio-emotional skills, such as collaboration, problem-solving, time management, and creativity.
