Method
Truss Bridge:
1) Before I started to make the Popsicle
sticks bridge, I used magnetic to build a fake
bridge. 2) After I built a magnetic bridge, I started building the Popsicle stick bridge. 3) First I took 4 Popsicle sticks and I made a straight line and I did the same thing on the other side. 4) Then I started to build triangles on both sides because triangles are strong shapes. 5) I joined the pieces together and made a truss bridge. Arch Bridge: 1) First I took some Popsicle sticks and made a fake arch shape on the floor. 2) Then I glued all the pieces together. 3) Then I made arch and glued the pieces together. 4) Then I made the road and joined all the pieces together to make the arch bridge. Testing:
1) First I took two chairs and I placed
the bridge in between the chairs.
2) Then my dad helped me to tie the bucket to the bridge. 3) I found some cars, water bottles and other toys. So that I could put it in the bucket and see when bridge will break. 4) I weighed each toy and put it in the bucket one by one. 5) I recorded the data. 6) I repeated step 4 and step 5 until the bridge is broken. |
