3D bar graph model for a science exhibition

Creating a 3D bar graph model for a science exhibition comparing subject marks versus scored marks is a great way to visually represent data.

Here’s a step-by-step guide using cardboard and color paper:

Materials Needed:

• Cardboard sheets
• Color paper (for bars and labels)
• Ruler
• Pencil
• Craft knife or scissors
• Glue
• Markers

1. Plan Your Data:
   • Decide on the subjects you want to represent and the corresponding scores.
   • Plan the range and scale of your bar graph based on the scores.
2. Create the Base:
   • Cut a large rectangular piece of cardboard to serve as the base of your 3D graph.
   • This represents the overall context or comparison.
3. Vertical Strips for Bars:
   • Cut several vertical strips from cardboard, each representing a subject.
   • The width of each strip should be consistent.
   • The length of each strip should correspond to the scores in that subject.
4. Color Paper for Bars:
   • Cut colored paper to cover each strip, representing the bars of the graph.
   • The color can be different for each subject, making it visually appealing.
   • Glue the colored paper onto the cardboard strips.
5. Add Labels:
   • Cut small pieces of color paper to create labels for each subject.
   • Write the names of the subjects on the labels.
   • Attach the labels at the bottom of each bar.
6. 3D Effect:
   • To create a 3D effect, cut small rectangles from cardboard.
   • Attach these rectangles vertically along the top edge of each colored strip, creating a raised edge.
   • This gives the illusion of a three-dimensional bar.
7. Score Numbers:
   • Cut small rectangles or squares from color paper to represent the scored marks.
   • Write the actual scores on these rectangles.
   • Attach these rectangles at the top of each bar to indicate the specific scores.
8. Display:
   • Arrange the bars on the base in a visually appealing way, leaving some space between them.
   • Ensure that the labels and scores are clearly visible.
9. Graph Title:
   • Create a title for your graph using color paper or markers.
   • Place the title prominently above the graph.
10. Explanatory Text:
    • Include a brief explanation or key to help viewers understand the data and the significance of the graph.
11. Stability:
    • If needed, glue the base and the bars securely to ensure stability during the exhibition.

This 3D bar graph model not only provides a clear representation of subject marks but also adds an engaging visual element to your science exhibition.
