12 simple science activities for little kids

Posted in Play and Activities.

Kids are the ultimate tiny scientists, exploring and experimenting with their world every day. Their incredible minds are soaking in information all the time, so it’s only natural that hands-on, science-based activities are a winner for most little kids, even from toddler and preschool age.

And best of all, science has huge lifelong benefits for kids, helping them to build skills they’ll take with them into their adult lives. Skills like:

  • Critical thinking and the ability to form their own opinion
  • A drive to experiment and explore
  • The ability to explain their thinking and listen to others
  • Researching, decision-making and problem-solving
  • Resilience, patience and perseverance
  • Finding and using evidence to support their theories
  • A healthy scepticism and interest in understanding the world around them

The world is filled with wonder and discovery at this age, and as parents we can ensure this sense of wonder stays with them for the rest of their lives. It’s as simple as involving them in fun ‘scientific’ activities from a young age – and here’s a few to get you started!
