Boat Carrying Capacity Science Fair Projects

Design a better boat for your 6th grade science fair project....

Boat Designs

When attempting to alter the design of a boat in your science fair project you first need to understand what design features are critical to the structure. In the case of a boat's design you need to make sure that its buoyancy is adequate for the size of its payload. This will require a little research and a little trial and error.

Radio Control Boats & Sail Boats

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. 3rd party contributor
