Electric Science: Make a Battery!
Since her toddler years, your child has probably gotten a big kick out of anything electric. Even two-year-olds can figure out, for example, that if you push the switch on that flashlight, you can make a bright light, not to mention the delights that come from a battery in your toy truck or train. But now that fourth grade is here (along with more complex electronic experiences as well), your child will learn more technical and scientific concepts as she explores the “why” behind the electricity she enjoys.
Here’s an experiment using simple household stuff to replicate discoveries that were first made centuries ago by the great Italian scientist, Allessandro Volta (if the last name “sparks” a memory of a certain electrical term, you’re right!). This is a great way to get even the most reluctant of scientists excited about electricity science! Don’t worry—there are no explosions in this experiment; but you can expect some delightfully “shocking” results.
