Easter is the perfect time for riddles and brain teasers. But what if this year's puzzles also taught your kids something about science and math? Here are 10 science-themed riddles at three difficulty levels — perfect for holiday fun.
The rules are simple: read the riddle aloud, let everyone guess, and tap to reveal the answer. Below each answer, you'll find a short explanation of the science behind it.
Easy (Ages 4-7)

Bonus Tip: Make It a Competition
Split the family into teams — maybe kids versus grown-ups? Award 1 point for a correct answer and 1 bonus point if the team can explain the science behind it. The youngest children can have an adult on their team as a "science advisor."
Feel free to write down your own brain teasers along the way. Some of the best riddles come from kids connecting something they've learned with their imagination.
