Lesson Planning
Why did the Romans use so many arches? Children conduct an investigation on effectiveness of different shaped arches by manipulating length of span and measuring height and load bearing strength.
Teaching Outcomes:
- To understand how arches were used in construction and why they are so strong.
- To gain knowledge of how forces act on arches and post and lintel style bridges.
- To investigate the strength of different shaped arches developing skills of measuring, fair testing and collaboration.
Children will:
- Understand why arches are strong and why they were used so successfully in Roman architecture.
- Conduct an investigation on the effectiveness of different shaped arches by manipulating length of span and measuring height and load bearing strength.
- Understand what is learned by the test and record the results.
