George tries to build a wall strong enough to keep cows out of his flowerbed in this video excerpt from Curious George: Keep Out Cows. He uses newspapers attached to a clothesline to make a barrier, but will that be strong enough to keep Leslie Cow and her friends away? In the accompanying lesson plan, children explore various building materials as they plan, construct, and then test out their own walls.
