5 Tips for Science Experiments at Home

  1. Get into character and add fun accessories if you have them, like lab coats and safety goggles.
  2. Have kids map out and hypothesize what they think will happen with a cheap notebook. They can even create and test their science experiments, writing the results in their lab notebook.
  3. Involve kids in every stage of the experiment and ask them questions!
  4. Remind kids it's okay to fail if the experiment didn't go as planned; that's the whole point of science and science experiments.
  5. Set up your space before the experiment, and ensure you have all the materials you need. You can use a science experiment checklist like this one from Science Sparks.
