Miss Cherie’s 1st Science Lesson

 

 

 

 

 

 

 

 

 

Lets talk about acids and bases…..

How can we clean dirty pennies?

 

 

 

 

We put some vinegar on some clean pennies to see what it would do over time…dirty pennies! Vinegar speeds up the oxidation process on pennies.

Look! When an acid like vinegar, and a base like baking soda mix, a chemical reaction happens (acids and bases are opposites). Bubbles!

Pennies are made out of metal–by the way, little people, what is metal? Silverware? Foil? A spatula?

We soaked dirty pennies in orange juice (acids), water (neutral), soap(base), baking soda (base), vinegar  (acid), and even ketchup to see which would clean our pennies the best. The acids work the best when cleaning the metal pennies and surprisingly ketchup does the job too because it has vinegar in it! Who would have thought?

We are blessed with God given scientific minds eager to discover His world!

What a fantastic lesson Miss Cherie! May God use you to unveil the mysterious wonders of His universe into the hearts of our Little Lambs! Great job!!!
