We’ve been making lots of paper chains recently, and have found that some are stronger then others depending on the material used, so we set about devising an experiment to find the material best suited to making paper chains.
Planning the experiment
Materials to make the paper chains with – tissue paper, parcel paper, cardboard, foil, gift wrap
How to test?
Gently pull on the chain till it breaks, recording the force needed to break the chain
Which factors do we need to keep constant?
Size of chain
Amount of sellotape used
Amount of overlap of each segment
Size of individual segments
Possible causes of errors
Hard to record the force used to break the chains.
Properties of a good paper chain
This activity is great for:
Key stage 1 Design and Technology
Improving skills, knowledge and understanding of an iterative design process.
Allowing children to design a purposeful, functional and appealing product for themselves and others.
Generating and developing ideas
Selecting appropriate tools and equipment.
Exploring and evaluating existing products and using features of those in their design.
