Tips for Science With Kids

Science with kids can be fun, but we want to make sure they’re learning while we play too! Here are some tips to make sure the lesson sticks while you have a blast with these experiments together!

  • Mess. Some of these projects can make a mess! Plan to do some of the more messy projects outside if you can, or embrace the mess indoors. Letting kids make a mess helps the learning process!
  • Lesson. Most of the sites that have the experiment tutorials include the lessons behind the experiments that will reinforce what they can learn from the project!
  • Questions. Encourage the kids to ask questions! Children are naturally curious and they will likely ask questions that will help back up what you’re trying to teach.
  • Hypothesis. Have kids make a hypothesis for what they think will happen before the experiment is started. Then when the experiment is complete, have them compare the results with their hypothesis!
