What to Look for in Science Toys

Recommended Age

Senior editor at The Toy Insider, Jackie Cucco says that there is not a set recommended age for all science toys across the board. Instead, she explains, "Toy manufacturers might look at whether or not the toy includes small parts, the difficulty level of the activities, and what science concepts are covered." She notes that when playing with science toys, it's important for them to be age-appropriate.


Safety can be a concern with some science toys on the market. According to Cucco, parental supervision is required. "Some science kits involve hands-on experiments that may require goggles or parental supervision," she says. "For example, if kids are playing with a candy-making kit that teaches them about the science behind cooking or mixing different ingredients, adult supervision would be required for handling a real stove. Kids should follow safety precautions so that they don’t get hurt."

Educational Value

Science toys foster learning through play. Cucco says they can cover topics like astronomy, anatomy, biology, chemistry, physics, geology, zoology, and more. "Kids can learn about the world around them and how things work by completing projects, experiments, and hands-on activities while they play," she adds.

  • 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 various age groups?

    If you're looking for science toys that work across various ages, Cucco suggests hands-on kits, as they're not too complex. Look for a toy that is not an experiment or something your child needs to break open or dig into (ex. 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.
