Building Raft Model
Well Done. You have learnt about tying the basic knots. To prepare for building a real raft next week, let us look at the materials needed and procedures for building a raft at the Raft Building session. Use your own materials, each group build a raft model (add a sail if you like) and post a video of it floating for at least 10 seconds at the forum below on or before Aug 5, 2015. Let us comment and vote for the best design on or before Aug 7, 2015. (Average time required: 1 hour)
