       Shining coins 
by III C-D
  We are ready to start about science investigation
                                            
We are squeezing a lemon


We pour the fresh lemon juice in a glass

  
We leave the coins for five minutes in the lemon juice
 




and then we dry the coins with paper towel
 

Surprise! We watched the difference!
       The coins put in the lemon juice look so clean and shine!
 
we write investigation's steps

 I like the lemon juice very much!
