My child built newtons cradle

Science

• The child has learned about the concept of potential and kinetic energy through observing the movement of the Newton's cradle.
• They have also discovered the concept of conservation of energy as they observed how the energy is transferred between the swinging balls.
• The child has gained an understanding of Newton's Third Law of Motion, as they observed how the equal and opposite reactions of the swinging balls.
• Through building the Newton's cradle, the child has learned about simple machines, such as levers and pendulums, which are involved in the movement of the balls.

For continued development, encourage the child to explore other hands-on experiments related to energy and motion. They could try building a simple pulley system or a ramp to further understand concepts of force and motion. Additionally, they could research and learn about other interesting scientific phenomena, such as magnetic levitation or the conservation of momentum.
