Using our knowledge of forces and friction, 5X spent time investigating a way of helping Eric (the grumpy yarl) move his boat.  Eric was complaining that his men were too tired to row after dragging the boat across the beach.  We decided friction was the problem.

After some serious thinking we put our thoughts into action with our own 'boat' and 'beach'.  We found that using water and wood helped to create a smoother surface and reduce the amount of force needed to pull the boat. 

Happy sailing Eric!
