What's a good physical science project to build with moving parts?

• Answer:

  Building a cardboard robotic arm is a popular science project in schools around the world. It is a simple, first step in robotics education. Students are given assorted supplies and asked to construct their cardboard robotic arm using only their creativity and ingenuity. 5 strips of cardboard measuring 3 inches by 22 inches. 10 scraps of cardboard of assorted sizes 4 feet of twine 4 feet of fishing line 15 rubber bands of assorted sizes 1 roll of masking tape 1 roll of clear tape 6 clothes pins 8 binder clips of assorted sizes 2 clothes hangers 15 paper clips of assorted sizes 4 pencils 10 small wire nails 15 popsicle sticks The cardboard robotic arm must have a sturdy base. If it is not secured it will topple over when it attempts to pick up the object. The cardboard robotic arm must have at least two parts to the limb. These are generally referred to as the biceps and the forearm. Some cardboard robotic arms also have hands or fingers. The cardboard robotic arm must have at least two joints. The elbow joint enables it to bend over to the object. The wrist or finger joints allow it to pick up the object. Some cardboard robotic arms also have a third joint at the shoulder near the base. The cardboard robotic arm must have a muscle system. This powers it through its motions. This can be human muscle pulling strings, hydraulics pushing liquid or electricity sending impulses to motors.
