Buoyancy and Displacement

CSEF · 2008 Physics & Astronomy

Daniel M. Winget · Fairmont Private Schools - Anaheim Hills, Anaheim Hills, Orange County

Overview

Objectives/Goals I am trying to find the boats ability to carry weight and see the changes in the weight when I change the water types. Methods/Materials My materials I used were a big container, a cup like model, marbles, salt,sugar, water,scale,a measuring cup, a stirring spoon, and a towel or rag. Results The salt water held a denser boat then second was the sugar water and last was fresh water. Conclusions/Discussion There was a 6 gram difference with salt to sugar water. There was also a 5 gram difference comparing sugar water to fresh water.

Summary statement

The density changes in the boats weight before it sinks in different types of water.

Help received

My mom helped me get the scale everything else was done by me.
