A fun way to introduce children to a scientific concept is to first say it in a silly way like why do animals hibernate? because they can’t have any hot chocolate! After the giggles are over it often times lead to a good discussion about the topic. For this purpose I often like to use Fake Science posters. They are quite fun and once we stop chuckling over the fake fact, we try to find out the truth and many times challenge ourselves to make a “true” version of the poster.
For example, take a look at the poster below “Why do potatoes and sweet potatoes taste different?” and challenge your kids to find out the truth and make a true version of this poster.
Take a look at the archives of this site where you will find many more interesting fake fact posters. A word of caution though, there are many posters which may not be suitable for children so make sure to check them out first before sharing them with children.
