tweaking and fixing our marble track was challenging because we had to make it go down with out making it fall. Every time we tried our track it did not work. So we made miner mistakes we fixed them we kept on trying it was fun because we played with the toys.Sometimes we made minor adjustments we were working together well.
never giving up we tried and tried to make our marble run wouldn't work. we kept on making modafaciatons every time Mrs King and filmed our marble track it fell of . we persevered till the end. it was very fun.
