How to make your pennies shine again!

Year 3 and 4 continued their science experiments with an investigation on immersing old pennies in different liquids and comparing the before and after results. 

The children immersed the penny into 5 different solutions for a set amount of time and used a control penny to compare their results. 

The liquids were water, lemon juice, tomato ketchup, vinegar and cola.

The results were amazing!

Be careful what you put on your chips!!
