They try to survive untill a boat comes to resvue them when they realize there is no way they will be able to escape via help they build their own boat. We stoped reading at that part

energy transformation

Hello today I'm going to talk about all the 8 types of energy. the first is kinetic energy it creates movment. the seccond is chemical potential it creates energy if needed. the thitd one is heat,heat is energy. light energy is energy that you can see. gravitational energy is energ that uses gravity an example is a ball roling down stairs it use gravitational energy electrical energy is in anything that uses power sound energy is an energy that you can hear an example would be vibrations today we used some of them to make a kind of slingshot made with a baloon and a plastic cup,we cut the under part of the cupand put the baloon there we used marshmellows for ammunition the types of energy that we used were elastic potential then kinetic energy and after gravitstional energy.
