My favorite lessons are ones in which my kids don’t even realize they are learning. The ones when I tell them it is the end of class and they say, “Awww, man!” My Line Plot Aluminum Boat lesson is one of those lessons. The kids build a boat out of aluminum foil that will hold pennies. After building the boat, they add pennies one by one until they sink the boat in water. Finally, the class records their results on a line plot. The kids love this hands-on lesson. Click here to download your FREE copy!
