Following on from lifting the rocks I decided last week to try out my new learning around pulleys and was soon joined by lots of helpers. The idea seems to be if you pull up twice as much rope you only have to pull half as hard. (See links on previous post.) So I set up what I hoped would be an effective pulley, modelling the trial and error nature of the experiment as I tested different setups. Then it was all hands on board to hoist each other up.

It still needs some work, but I'd like to set it up so a child can lift something with the pulley they couldn't on their own. One problem might be is there a difference between lifting and holding the weight. Maybe gears and brakes might have to be used?

Tino pai rawe tamariki! I would have loved to have been Anna...being lifted up like that. What great teamwork and fantastic learning.
