Prepare a model of a plant cell or an animal cell.

Materials Needed:

For both plant and animal cell models, you'll need:

Styrofoam ball (for the main cell structure)
Paints or markers (for coloring)
Various small objects (for organelles)
For example, beads, buttons, small candies, beans, etc.
Glue or toothpicks (for attaching organelles)
Cardboard or sturdy paper (optional, for base support)
Plant Cell Model:

Start with the styrofoam ball as the main cell structure.
Paint the styrofoam ball green to represent the cell membrane.
Use smaller objects like beads, buttons, or candies to represent the organelles:
Large circular candies or beads can be the central vacuole.
Smaller round objects can be chloroplasts.
Use small beans or buttons for other organelles like the Golgi apparatus, endoplasmic reticulum, etc.
Attach these organelles onto the styrofoam ball using glue or toothpicks.
You can also use markers to label each organelle.
Animal Cell Model:

Similarly, start with a styrofoam ball.
Paint the ball any color you like to represent the cell membrane.
Use small objects to represent the organelles:
For example, small beads can be mitochondria.
Different colored beads or buttons can be used for the nucleus, Golgi apparatus, endoplasmic reticulum, etc.
Attach these organelles onto the styrofoam ball using glue or toothpicks.
Label each organelle using markers or small pieces of paper.
Optional Base:

You can create a base for your cell models using cardboard or sturdy paper. Simply cut out a circular or square piece to serve as a stable platform for your cell model to sit on.

Once you've assembled your models, you can use them for educational purposes or as visual aids for presentations. Feel free to customize the models based on your preferences and available materials.
