Here is another easy experiment by Little Scientist Diego. He learnt that lemon juice is an acid and that Water is not an acid. And in the process he made a few pennies shinier 🙂
Tools: two beakers, tweezers, bigger bigger
Extras: dull pennies, water, lemon juice, paper towels
Key science concepts:
Lemon juice is an acid. Water is not an acid.
What to do:
Check the video to follow the instructions from little scientist.
Which penny is shinier? The penny that was in the lemon juice is shinier because the lemon juice is an acid and the acid broke down the tarnish on the penny.
