Connects

Today we did connects we made a well it was very hard to build but we got through all of the hard steps. First we built the frame  then we built the bit for the  string to  hang on to then we built the lever for it to go up and down then we  built the bit were you can put things in. That was my first time building a proper connect structure.

 

 

Pulleys

We made pulleys today first we got a cotton rill, wire, yoghurt cup and string. we put the wire through the cotton rill and tied it p with wire then put little holes in the yoghurt cup and put wire through that. Put the string around it and there was out easy pulley we made two other one they were harder to make. I learnt haw to make easy and hard pulleys with one cotton rill two cotton rills and four cotton rills. The one  with the four cotton rills did not work because the string got tangled around the rills so that one did not work but the others did. I want to know how many cotton rills you could make one pulley have. I liked doing pulleys.

 

Putting them all together

Went we out them all together we had to make another pulley but when we tried to have the pulley to drop a marble into the Lego funnel it did not work because  the marble did not land in the right place. So then we tired to put string around the windmill that Ashleigh’s group made but that didn’t work either.
