There our 2 tests penny stack and penny spread. The penny stack is when you see how much pennies you an stack on the bridge and the penny spread is to see how much pennies you can spread on the bridge. On the penny spread we got 5 pennies and on the penny stack we got 35 pennies.]]> 2016-10-13 17:23:00 UTC https://padlet.com/8637510/92j4reczzkoh/wish/130533149 8637510 https://padlet.com/8637510/92j4reczzkoh/wish/130537143 some thins that i would do differently is to the bridge sturdier and to make sure that the beams are sturdy enough for the pennies to go on. I would build a different one because he one we had was wobbly and i would add more supports.]]> 2016-10-13 17:32:19 UTC https://padlet.com/8637510/92j4reczzkoh/wish/130537143 8637510 https://padlet.com/8637510/92j4reczzkoh/wish/130620354 our beautiful model]]> 2016-10-14 00:04:18 UTC https://padlet.com/8637510/92j4reczzkoh/wish/130620354
