4 Candy Science Experiment Tips

These 4 tips will help make sure your candy science experiments go smoothly.

  1. Do a little prep – Science can get more than a little messy. So, you’ll want to prep the space you’ll be working on. Use plastic tablecloths on your work surface as well as the floor, and catch any mess by working on a plastic tray or cookie sheet. Don’t forget to dress your kids (and yourself!) in clothes you don’t mind getting covered in candy.
  2. Have some extra candy – You’ll want to have some extra candy on hand for your experiments. Things sometimes go wrong, and you’ll want to have extra candy for a do-over. Even if things go as planned, your kids may want to do the experiment again – and again!
  3. Choose fresh – Whenever possible, you’ll want to use fresh candy to make sure the experiment will work the way it should. One of the best times to try a candy science experiment is right after those big “candy” holidays – Halloween, Easter, Valentine’s Day – when you have plenty of extra candy on hand that you want to get rid of.
  4. Be patient – A good scientist knows that sometimes you need to try an experiment more than once before you get it right. If an experiment fails, it’s hard not to get discouraged. Let your child know that it’s just part of being a scientist.
