Floating & Sinking

After learning about the RNLI last week, we decided to test different materials to see which would be the best material to make a lifeboat with. We wanted to test each material to see if it would sink or float in the water. We tested wood, metal, plastic, glass, fabric, paper and leather. We recorded our findings using this table:

 

     

 

Material name

Sink

Float

Wood

 

 

Plastic

 

 

 

 

 

 

 

 

 

 

 

 

Which material would you choose to make a lifeboat with? Why?

We are going to make our own lifeboats tomorrow!
