Mighty Monument Challenge

Leicestershire / South Nottinghamshire

Mighty Monument Challenge

  • Mighty Monument Challenge

    What's it about?

    This inspiring primary school Challenge is to design and build a lightweight free-standing structure, themed on a monument. Using materials from a given list, the structure should support as much load as possible, up to a maximum of 10kg, held in a container whose base is at a height of 900mm. The Challenge is focused on the concept of ‘strength to weight ratio’ rather than outright weight holding capacity. Therefore, a lightweight structure holding less than 10kg could potentially outperform a heavier structure that supports the maximum load.

    The monument may either be themed on an existing world monument or pupils may research and construct a monument to honour a person or event relevant to the school’s locality.

    Judges will be looking for evidence of STEM learning into structures and forces, design and material experimentation and creativity in theming.

    Eligible school year groups: 3-6

    Entries accepted from: Individuals or teams of 2-5 students. Schools may submit a maximum of 3 entries for the Challenge. Teams may be mixed age if desired.

    Open to: Leicestershire and South Nottinghamshire Schools, Academies and Private Schools. Home-educated children may also participate. See our Terms and Conditions.

  • British Science Association CREST Awards

    CREST Discovery Awards

    3M will pay for entries for the Mighty Monument Challenge to be submitted for a British Science Association CREST Discovery Award. See our Terms and Conditions. Please indicate your consent on the Entry Form.

Important Dates

Closing date for entries: 24 March 2022

Judging: 10, 11 and 12 May 2022 at 3M, Charnwood Campus, Loughborough . Please indicate your preferred date/time on the entry form.

Entries will be screened to ensure they meet the entry criteria. Students will be asked to deliver a presentation of up to 10 minutes length to demonstrate their monument and talk through their background research, material selection, design experimentation and construction processes. The judges will ask questions about the monument and their STEM learning. All members of a team should play a part in the presentation.
  • Judges will check the materials used and the dimensions of the monument and position of the loading container are in line with the rules
  • The finished monument will be weighed using digital weighing scales and the weight recorded
  • Testing blocks of known weight (e.g. 100g, 200g, 500g, 1kg) will be added to the container in increments up to a maximum load of 10kg. More than one block can be added at the same time, if desired, to maintain stability
  • Testing will stop when either:
    • the monument breaks or falls over
    • the load is no longer supported at a height of 900mm
    • the entrant/team requests that no further load is applied
  • The maximum load held will be recorded
Mark Scheme

Up to 40 marks for the structure's performance, based on the ratio of load carrying capacity to the structure’s weight.

Up to 25 marks for evidence of STEM learning including:

  • idea generation
  • background research
  • material selection
  • prototyping
  • design
  • overcoming problems and challenges

Up to 15 marks for quality of the presentation

Up to 20 marks for the monument’s theming, appearance and visual appeal

Total marks available = 100

The students’ year group will be taken into account when awarding marks.

Judges will select 4-6 finalists who will be invited to attend the 3M Young Innovators Challenge presentation event on Friday 17 June 2022, where the winner will be announced.

£750 of science or engineering equipment for school use plus a £50 gift voucher for the winning individual or team member. All finalists and their schools will receive a framed certificate.

All entrants will receive a certificate of entry and personalised feedback from the judges.

Year 5 Forces and magnets

Pupils should be taught to:
  • explain that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object
  • identify the effects of air resistance, water resistance and friction, that act between moving surfaces
  • recognise that some mechanisms including levers, pulleys and gears allow a smaller force to have a greater effect
Links to Design and Technology Curriculum (England)

Key stage 2

When designing and making, pupils should be taught to:

  • use research and develop design criteria to inform the design of innovative, functional, appealing products that are fit for purpose
  • generate, develop, model and communicate their ideas through discussion, annotated sketches, prototypes
  • select from and use a wider range of tools and equipment to perform practical tasks
  • select from and use a wider range of materials and components, including construction materials
  • investigate and analyse a range of existing products
  • evaluate their ideas and products against their own design criteria and consider the views of others to improve their work
Technical knowledge
  • apply their understanding of how to strengthen, stiffen and reinforce more complex structures
Links to Geography Curriculum (England)

Key Stage 2

Pupils should extend their knowledge and understanding beyond the local area to include the United Kingdom and Europe, North and South America. This will include the location and characteristics of a range of the world’s most significant human and physical features. They should develop their use of geographical knowledge, understanding and skills to enhance their locational and place knowledge.
Pupils should be taught to:

Place knowledge
  • understand geographical similarities and differences through the study of human and physical geography of a region of the United Kingdom, a region in a European country, and a region in North or South America
Geographical skills and fieldwork
  • use maps, atlases, globes and digital/computer mapping to locate countries and describe features studied
  • use fieldwork to observe, measure record and present the human and physical features in the local area using a range of methods, including sketch maps, plans and graphs, and digital technologies
