Discuss and practise making your model (60 minutes)
You will make a model of your structure. Discuss how you will do this in your group.
Think carefully about all the materials you will need to build your model. Do you need paper, glue, and/or corrugated cardboard? And what about tools? Do you need scissors or glue-guns?
Write a complete list of all the materials and tools necessary to build your model.
You need a plan to help you stay organised. Ask yourselves questions such as:
- What should we do first?
- What materials do we need for each step?
When you have decided what you will do, add it to your flow chart. Each member of your team should draw up his/her own copy of the flow chart.
The following activity will help you to make strong structures out of paper. You can use these structures to help you build your model bridge.
Make a model of your bridge (60 minutes)
Build one model for your team that looks like your working drawing. It should be built neatly, safely and to scale. You can use materials available to you such as cardboard, string, wire, pieces of wood, drinking straws, plastic and clay. You can also use glue and paint.
Be aware of safety at all times, especially when working with blades and toxic glues (Wood glue, Prestik and Pritt are fortunately not toxic.).
Remember to follow the steps as shown in your flow chart. Everyone must be involved with making the model.
