Method 1: The Simple Paper Mache Globe (Beginner-Friendly)

This method is fantastic for younger children or anyone looking for a quick and easy way to create a basic globe model. It’s messy but fun!

Materials You’ll Need:

• An inflatable balloon (round shape works best)
• Newspaper, torn into strips
• Flour
• Water
• A bowl for mixing paste
• Paint (blue, green, brown, and optional colours for details)
• Paintbrushes
• A marker or pencil
• Optional: A small stand or jar lid to serve as a base

Step-by-Step Instructions:

1. Prepare the Balloon: Inflate your balloon to the desired size of your globe. Tie it off securely.
2. Make the Paper Mache Paste: In your bowl, mix approximately one part flour with two parts water. Stir well until it forms a smooth, slightly thick paste (like a thin pancake batter). If your paste is too thick, add a little more water.
3. Apply the First Layer of Newspaper: Dip a strip of newspaper into the paste. Run the strip between your fingers to remove excess paste. Apply the strip to the balloon, slightly overlapping other strips. Cover the entire balloon with this first layer of paper mache.
4. Repeat Layers: Allow the first layer to dry completely (this can take a few hours or overnight). Then, repeat the process, applying two or three more layers of newspaper strips dipped in paste. This will provide a strong and durable base for your globe. Be sure to let each layer dry fully before starting the next one.
5. Let it Dry Completely: Once you’ve applied all the layers you need, allow the entire paper mache balloon to dry completely. This may take 24-48 hours depending on the thickness of the paper mache and the humidity of your location. It needs to be rock-hard to handle painting.
6. Deflate the Balloon: Once the paper mache shell is completely dry and hard, carefully pop the balloon. Remove the deflated balloon pieces from inside the paper mache globe. You should now have a hollow sphere.
7. Painting the Base Layer: Once you have a dry, hard, hollow paper mache shell, start painting. Use a base coat of blue paint over the entire sphere to represent the oceans. Let this layer dry completely.
8. Add the Continents: Now, using your marker or pencil, lightly sketch the continents onto your blue globe. You can use a reference map or globe for guidance. Once you’re happy with the outline, paint the continents using green and brown paints. You can even add smaller details like mountains or deserts. Let the paint dry completely.
9. Optional Details: You can add further details like polar ice caps (using white paint), or even use markers to draw in countries or major cities.
10. Display Your Globe: Place your finished globe on a stand or use a jar lid to keep it upright. You’ve now created your own Earth model!

Tips for the Paper Mache Globe:

• For an extra smooth surface, you can add a final layer using white paper (like printer paper) instead of newspaper. This makes the colours more vibrant when painting.
• If the balloon doesn’t inflate in a perfect sphere shape, you can try layering a little extra paper mache on the uneven areas.
• Be patient, allow each layer of the paper mache to dry completely, this is crucial for the end results.
• Don’t apply too much paste. It’s better to use a thin layer of paste and multiple layers of newspaper rather than having the paper soggy and falling apart.

Method 2: The Foam Ball Globe (Intermediate Level)

This method is great for creating a more precise and durable globe model. Foam balls are readily available and create a good base.

Materials You’ll Need:

• A foam ball (various sizes are available)
• A marker or pencil
• Acrylic paints (blue, green, brown, and optional for details)
• Paintbrushes
• A small, pointed tool (like a toothpick or skewer – adult supervision required)
• Optional: A thin wooden dowel rod for a stand
• Optional: A print-out of a world map or globe for reference

Step-by-Step Instructions:

1. Prepare the Foam Ball: If desired, you can insert the wooden dowel into the bottom of the foam ball to create a stand. If the ball has an existing small hole or indent from the manufacturing, that’s an ideal spot for this.
2. Sketch the Continents: Using your marker or pencil and the map printout (if using), lightly sketch the outline of the continents directly onto the surface of the foam ball. Try to be as accurate as possible with their shapes and placement.
3. Paint the Base Layer: Paint the areas around the continents with blue paint to represent the oceans. Allow the blue paint to dry completely before proceeding.
4. Paint the Continents: Now, paint the sketched continents with green and brown paints. Use reference images to ensure the colors are accurate. You can even add details, like painting mountain ranges with slightly darker shades.
5. Add Details: Using your pointed tool, you can carefully make small indentations to represent mountains, rivers, or other features on the Earth’s surface. Alternatively, you can use a fine-tip paint brush to add these features instead of indentations. Add colours of white or light blue to represent the ice caps of the North Pole and South Pole.
6. Let it Dry Completely: Allow the paint to dry completely before handling your globe.
7. Display Your Globe: Place your completed globe on the stand or rest it on a flat surface. It’s a robust and accurate miniature of our planet!

Tips for the Foam Ball Globe:

• To avoid the paint from running or bleeding, apply thin coats of paint and allow them to dry between coats.
• Use a fine-tip brush to paint detailed outlines of the continents.
• When using a pointed tool to create details, be careful and supervise children.
• If you want to create a highly accurate globe, you can purchase a map decal to wrap around the foam ball, or print a flattened map and carefully apply it to the globe with adhesive.

Method 3: The Advanced 3D-Printed Globe (Advanced Level)

This method offers a very precise and professional-looking globe, but it requires access to a 3D printer. It’s a great option for older students or anyone wanting a detailed and accurate model.

Materials You’ll Need:

• Access to a 3D printer
• 3D printing filament (various colours available – white, blue, green, brown)
• A 3D model of the Earth (available online on websites like Thingiverse)
• Optional: Sandpaper for smoothing
• Optional: Paint or markers for details

Step-by-Step Instructions:

1. Find a 3D Model: Search online for a free 3D model of the Earth. There are many options available, some are already split into different segments for colour printing. Choose a model that suits your needs and printer capabilities.
2. Import the Model: Import the 3D model into your 3D printing software.
3. Prepare the Print Settings: Adjust the printer settings according to the filament type and the model’s requirements. Ensure that the model is positioned correctly for optimal printing and use support material if necessary for the overhanging parts.
4. 3D Print the Model: Start the 3D printing process and wait patiently. This can take a few hours, depending on the model size and complexity.
5. Remove Support Material: Once the model is printed and cooled, carefully remove any support material that was used during the printing process.
6. Optional Smoothing: If the model has rough edges, use fine sandpaper to gently smooth them.
7. Optional Painting and Details: You can paint the 3D-printed globe to add more detail or use markers to label countries or features. If you printed the model in different pieces of filament, you can assemble them now, after the painting or detailing step is complete.
8. Display Your Globe: Your 3D-printed globe is now ready to be displayed. It’s a very accurate and durable model of the Earth.

Tips for the 3D Printed Globe:

• Make sure your printer is properly calibrated before attempting to print the model.
• Consider printing the model in multiple sections if it is very large, for an easier print and assembly.
• Experiment with different filament types and colours for varying effects.
• For increased details, research which free 3D models you can find online. There are many which are designed with specific cartography in mind.

Beyond the Basics: Advanced Detailing and Customization

No matter which method you choose, there are numerous ways to further enhance your Earth model:

• Latitude and Longitude: Using a fine-tip marker, you can draw lines of latitude and longitude onto your globe for added educational value. Use a reference image for accuracy.
• Political Boundaries: Use different colours to paint political borders and countries onto your continents. This will also add an extra layer of learning.
• Land Features: Adding details like mountain ranges, rivers, and deserts will enhance the realism of your globe. You can use a small brush or markers to add these details.
• Textured Elements: Try using textured paint or materials like sand, or cotton to create more realistic terrain on your model, or even glue cut-up pieces of dried pasta for rocky mountains.
• A Rotating Axis: If you are skilled with simple tools and basic mechanics, you can add a rotating axis to your paper mache or foam globe model by inserting a dowel rod through the center and mounting it on a base allowing it to spin.
• Glowing Paint: Adding glow-in-the-dark paint to some areas of your model, especially stars surrounding the earth, will make it a fun decorative feature at night.
