10 slides to explain the concept of upthrust to my class of Upper Juniors. Designed to be used AFTER they have weighed objects in air and in water and noticed the difference in weight.

    Hi, weight is generated from gravity acting on mass. Gravity is a constant on any given planet (actually its not but for simplification we teach it as if it is). Its a common misconception that gravity itself is a force but infact its the weight thats the force cuased by gravity acting on a mass.

    just be careful when going overthese terms with students. IOP is a great resource for explanaition on this topic

    Not trying to be a pain its just these are mistakes I have to sort out with my students every year.
