1. Babysitting is temporarily caring for a child. Babysitting can be a paid job for all ages; however, it is best known as a temporary activity for young teenagers who are too young to be eligible for employment in the general economy. It provides autonomy from parental control and spending money, as well as an introduction to the techniques of child care.
2. Rocketry has existed for hundreds of years. Although the technology has greatly improved and there are numerous methods for propelling a rocket, the simple science behind rockets has always been the same. To propel a rocket, some kind of force must push it forward. A force is the amount of push or pulls on an object. The mechanical force that pushes a rocket or aircraft through the air is known as thrust. In this experiment, you’ll make a balloon rocket that is propelled by the pressure. The pressure is the amount of force exerted on an area.
When you blow up the balloon, you are filling it with gas particles. The gas particles move freely within the balloon and may collide with one another, exerting pressure on the inside of the balloon
