What is slime? A general definition states that it is a sticky substance with textures that are neither solid nor liquid. Technically, slime should ooze between your fingers but not stick to your skin!

A basic slime recipe is generally made by creating a borax and glue chemical reaction but has since become an object with many different ingredients. Floam, fluffy slime, edible slime, magnetic slime, erupting slime, chalkboard slime…there are so many possibilities for endless ooey gooey fun!

The Merits of Slime Science Projects

A growing interest in hands-on STEM education has brought slime science to the forefront in recent years. It’s no longer just a fun, gooey toy. It’s a learning tool for kids from preschool on up!

For younger kids and older kids that are working on fine motor skills, slime is a wonderful tool. Kneading, mixing, pulling, stretching, and digging through slime is engaging, gross fun for kids – and a great way to use their hands and build up strength that they might not have the opportunity for in day-to-day life.

Working with slime is also a sensory experience. Kids who crave sensory input will love experimenting with different slime textures and smells. Making slime recipes is a great way to encourage your child to get hands-on with safe, appropriate materials that stimulate their senses.

Working with slime science projects is a great way to get a WOW reaction from kids young and old. Preschoolers learn that they can mix different materials together to create something new. Older kids can dig deeper and learn about polymer science and apply what they’ve learned to their experiments.
