Building A Catapult . A building a catapult is an awesome STEM activity because kids are learning so many things. A catapult is an ancient weapon or a ballistic device used mainly to launch stones spears and projectiles to a greater distance without the help of explosives.
Building catapults is a great way to learn about physics even at a very young age. Cut the first 1 piece of wood to a length of 31 in. Cut the third 2 pieces of wood to lengths of 34 in.
Cut the fourth 2 pieces of wood.
IKatbag shows us a simple way to build a catapult with recycled materials and materials you have around your home. Cardboard Box Use a cardboard box. You can build it into the wood by carving into the end so it becomes concaved like a cup or you can use a paper cup or a small box then attach it to the arm with nails thumbtacks or glue. Teaching kids how the catapult works along with just how to build it is important to make the STEM connections in this activity.
