Benefits of Science Experiments for Kids

Science for children means a lot of things. It’s not something exclusively meant for children of school age — appreciation for science actually begins from infancy (1).

For children, doing science starts with curiosity, then exploration, and lastly, discovery. All of these traits come naturally, especially to younger kids such as infants and toddlers. These are the months and years where they’re eager to learn cause and effect.

It’s essential for us parents to encourage this (2). Encouraging your child to do science projects, no matter the age, could yield great benefits long term. Science can help develop skills such as resourcefulness, goal-setting, problem-solving, and planning (3).

It nurtures the intellectual side of their curiosity. This, in turn, pushes them to ask questions and learn to understand what’s going on around them.

How to Choose a Science Kit for Kids

When you’re searching for science kits, you may become overwhelmed with all the different options. But the truth is, the best science kits for your little scientist are those that revolve around a subject of interest. Let’s look at a few:

  • Chemistry: This may include color-changing chemicals, invisible ink or perhaps growing crystals.
  • Biology: This is a wide subject and could involve anything from growing plants to learning about DNA.
  • Physics: Again, a broad subject, where perhaps you’ll build a robot, or learn about momentum and energy.

There are, of course, other good-to-have features in a science kit. Here are a few:

  • Fully equipped: Many recommend looking for a kit where all the equipment is already included. You can easily do science projects with items at home, but for younger kids especially, it’s better to have everything ready to use.
  • Step-by-step guidance: Look for a science kit that has a step-by-step approach rather than giving free roam. This simulates that of a classroom learning experience and is more likely to succeed.
  • High quality: This is an important feature, not only for the result of the project but also for your sake. When you’ve purchased something that will work like it’s supposed to, your child is more likely to be enthusiastic — and it’s safer.

It’s essential to find a science kit that is age-appropriate. Those meant for older children often require more technical skills, which might be too difficult or unsafe for younger children.

  • Ages 4 to 6: Children in this age group often enjoy things that are hands-on and will show quick results. Consider activities such as simple, safe experiments or handling miniature dinosaur fossils.
  • For 7 to 9-year-olds: Look for a kit that involves experimenting using basic scientific principles. These typically include more detailed instructions and may prepare your child for science in school.
  • From 10 to 12 years: Look for something they can do without your assistance. A good idea is to build on skills they’re already learning in school.
  • Ages 13 and up: In this group, your child can advance to something more complicated. This is the perfect time to bring in the robot-building kits.
