Stomp Rocket Jr Glow Toy
The Spruce / Danielle Directo-Meston

"The foam rockets are very soft, so they won’t do much damage if they hit anyone below the neck. Although the manufacturer notes that the toy is good for indoor and outdoor play, we really only recommend the latter, as we had a few close calls with our TV and other objects."—Danielle Directo-Meston, Product Tester

What to Look for in Science Toys

Recommended Age

Even the youngest science enthusiasts can play with science-themed toys, as long as they’re age-appropriate. Toys with small pieces, complex construction, and electrical components are best saved for older children. Little scientists will love cause and effect toys, like stomp rockets, that they can engage with physically.


Always follow the safety instructions of your child’s toys. This is especially important when playing with science-based toys that include small pieces, circuits and electricity, pointy tools, and chemical solutions. Many science toys come with goggles and other safety precautions to teach your child how to be safe as they play and explore.

These safety measures can be applicable beyond the toy or activity. “One of my favorite examples of a good STEM activity is cooking,” says Chuck English, Virginia STEM Coordinator at the Science Museum of Virginia. “Measuring, fractions, math, impact of recipe, procedure in a lab, outcomes. You can teach good kitchen safety precautions.”

Educational Value

Science toys are fantastic at combining learning and play. Consider your child’s interests and school curriculum to choose a toy that incorporates other things that they are learning to get the most educational bang for your buck. A dinosaur enthusiast will love toys that allow them to be a paleontologist, while a budding chemist will gravitate toward a chemistry set.

  • What science toys are the best for kids 5 and under?

    For children that are 5 years of age and younger, you'll want to avoid toys with small pieces, liquids, and anything that could pinch a finger or has sharp points. Simple toys, such as books, stuffed animals, large figurines, or soft-sided science-themed items are great options.

  • What are the least messy science toys?

    Avoid science toys with liquids, powders, and tiny pieces if you want to keep messes to a minimum. Stomp rockets or other toys that only have a few larger pieces can provide science-themed fun while avoiding the mess of chemical and liquid experiments. Otherwise, playing with science toys outdoors can help keep the mess out of your home.

  • Where can I find a long-lasting science toy that works across age groups?

    There are numerous science toys available online as well as in brick and mortar stores but they won't all last as long as others. Look for a toy that is not an experiment or something your child needs to break open or dig into (a geode or fossil kit). Toys sold for schools to use in classrooms are usually designed to last a long time and include things like anatomy models, magnets, and puzzles that have science themes.

  • What are the best science toys for kids who love chemistry?

    Kids who love chemistry usually enjoy doing experiments. Chemistry sets for children will include ingredients and supplies to perform basic experiments at home and can introduce kids to common chemical reactions. Be sure to check the recommended ages for the specific chemistry set you are looking at before purchasing it. Not all sets are designed for all ages of kids.

  • What are the best science toys for kids who love biology?

    Biology is the study of life; there are a lot of different living things in the world, so biology toys are numerous. They can include human and animal anatomy models, microscopes to look at cells, botany kits, and more. Depending on which aspect of biology your child is most attracted to, great ideas in this category include plant-growing kits, insects in resin, or a human anatomy model that you and your child can put together.
