This is a great program to download....but ask mum & dad's permission BEFORE you download anything onto your home computer.
This program is the one we used in Technology Class. See if you can make the least expensive bridge..it's not as easy as you think!(Especially if it needs to be structurally sound & able to carry loads!!)
Let us know how you went with the class activity. Was your bridge a success? Did it pass the load test? What did you learn from this activity?
