Benefits of Science Experiments for Kids
Science for children means a lot of things. It’s not exclusively meant for children of school age — appreciation for science begins in infancy (1).
For children, doing science starts with curiosity, then exploration, and lastly, discovery. All of these traits come naturally, especially to infants and toddlers. These are the months and years when they’re eager to learn cause and effect.
It’s essential for us parents to foster a love of learning and exploration (2). Encouraging your child to do science projects, regardless of age, could yield incredible long-term benefits. Science can help develop necessary life 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 happening around them.
How to Choose a Science Kit for Kids
When you’re searching for science kits, it’s easy to become overwhelmed by 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, slime-making, baking, or growing crystals.
- Biology: This broad subject could involve anything from growing plants to learning about DNA.
- Physics: Another broad subject that includes activities such as building a robot or learning about momentum and energy.
There are, of course, other good-to-have features in a science kit. Here are a few of the ones we look for:
- Fully equipped: We recommend looking for a kit where all the equipment is already included, as it makes the process much easier. You can easily do science projects with items at home, but for younger kids, it’s better to have everything ready for use.
- Step-by-step guidance: For younger children, we look for science kits that have a step-by-step approach rather than giving free roam. This simulates that of a classroom learning experience and is more likely to succeed. Open-ended experimenting is suitable for older children who already grasp cause and effect and can make their own predictions and observations as they go.
- High-quality materials: This is one of the top criteria we look for in the best science kits, not only for the project result, 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 an age-appropriate science kit. 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 hands-on tasks that show quick results. Consider activities such as simple, safe experiments or handling miniature dinosaur fossils.
- Ages 7 to 9: 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.
- Ages 10 to 12: Look for something your child can do without your assistance. It’s a good idea to build on skills they’re already learning in school.
- Ages 13 and up: In this group, your child can advance to more complicated tasks and instructions. This is the perfect time to bring in the robot-building kits.
