Kahn Academy- Physics- Force

Room 4 received a set of 6 iPads from our technology grant last spring. We use our devices for reading, researching, and practicing math concepts. First graders use the Kahn Academy app to read and research key concepts of structures. I love this time of year! My 6-7 year olds are not just practicing building structures, they are experimenting with, and asking bigger questions about how and why these structures stay up!

An actual bridge is selected. The design, a simple beam bridge is examined. How will force (weight added ) hold up the structure? 

Here, the lesson illustrates force being applied to a model bridge. TOO MUCH force, the bridge collapses!
