Materials Required:
Styrofoam balls or other shapes (e.g., cubes, cones)
Construction paper
Scissors
Glue
Toothpicks or small wooden dowels
Paints and brushes
Markers
Labels or tags
Craft knives (for teacher use or with supervision)
Steps Involved:
Choose a Styrofoam Base: Provide students with a large styrofoam ball or another shape to serve as the base of the cell model.
Cut the Styrofoam: Carefully cut the styrofoam shape in half to reveal the inside of the cell. This can represent either a cross-section of the cell or the entire cell.
Create Organelles: Using construction paper, smaller pieces of styrofoam, or other craft materials, students will create the different organelles, such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus.
Assemble the Cell: Attach the organelles to the styrofoam base using glue or toothpicks, arranging them to reflect their positions within a real cell.
Decorate the Model: Paint and decorate the cell model to make it more visually appealing and accurate, adding color to represent different cell parts.
Label the Organelles: Use small tags or labels to identify each organelle, either by sticking them directly into the styrofoam or attaching them to toothpicks.
Discuss the Model: Have students explain the function of each cell part as they assemble the model, promoting verbal reinforcement of their learning.
Present the Model: Allow students to present their completed models to the class, discussing how each part contributes to the cell’s overall function.
Reflect: Encourage students to reflect on how constructing a 3D model helped them understand the structure and organization of a cell.
