Best science experiment kits for kids 3 years old (Gift Review)


There is nothing that will light up your toddler’s eyes more than a brand-new shiny toy. Three-year olds are energetic and curious about the word around them. You will often find that if you leave them out of your sight they often get in trouble. Although their energy can be endearing it is a sign that they need more stimulation and fun.

Three-year olds without any toy to tinker with automatically become anxious and bored. They may even turn to attention getting antics just to have some stimulation such as crying or making a mess. Don’t turn your three-year-old into something hard to handle. Give them safe and stimulating toys that will challenge their cognitive development and give then sensory stimulation.

Science experiment kits for kids may just be the best toy that will nurture your next little Einstein. Science experiment kits don’t just entertain but give your kids the necessary enjoyment but also gets them ready for math and science subjects. Your kids will learn cause and effect which will teach them about how the world works. Grab a science experiment kit now and give your kid the chance to be a little genius.

How Your Three-Year-Old Plays

Cognitive development in a 3-year-old isn't just about learning the alphabet or how to count. It envelops the entire learning process of absorbing information, which includes asking questions, and processing and understanding information.

Most 3-year-olds are like sponges and they absorb everything around them. As a parent, help them know what to do with that information. Because they are now able to sit still and focus for a longer period of time, they can take in even more around them.

Your child’s mind and imagination ill grow this year, and they will start to improve their memory and understand more of the world around them. You will be asked tons of questions, and there may be times you won’t even know the answers to their thought provoking questions. Be patient because asking is a child’s way of learning.

It can be a challenge to know what your child actually does understand and what still needs to be learned, but these are some of the milestones you look for them to achieve by the end of the year.

  • Play

As noted above, instead of engaging in parallel play, your 3-year-old may begin to play with other children and even develop friendships. Kids can begin to take turns at this age so you may see your child begin to engage in simple games or activities that require them to practice patience.

Key Milestones

  • Enjoys listening to books and may even attempt to "read" it on their own.
  • Identifies basic shapes and colors.
  • Says the alphabet.
  • Your child may know about 300 words by now.

Here are some of the best science experiment kits for kids 3 years old.
