An activity available in three levels for years 3 – 10
Taking Approx. 1 – 2+ hours

When engineers wants a strong, stiff two dimensional shape they will use triangles. For three dimensional structures the choice becomes Tetrahedra.

This activity explores this in a way which is fun. It calls for teamwork, cooperation, organisation and imagination, whilst introducing an element of competition.

A flexible session with a 'zero' material cost.
Standard Activity : Level 1 – Suitable for year 3 upward

Teams of children compete to build the highest stable structure using standard length pieces of dowel and elastic bands in a given time.
This activity takes approx 1 – 1 ½ hours.

Trading : Level 2 – Suitable for year 5 upward

Teams are given an insufficient number of sticks in a mixture of colours, but must build the structure in a single colour.  Further sticks are available by trading with other teams or with a ‘bank’
This activity takes approx 1 – 2 hours. 
Bridges : Level 3 – Suitable for year 10 upward
Teams are challenged to span a chasm by a self-supporting bridge constructed with sticks and elastic bands.  The structure must not sag and there must be a recognisable roadway.  The longest bridge Wins!
This activity demands a high degree of vision, planning, good organisation, delegation and coordination.
This activity takes approx. 2+ Hrs
