Sensory Activities for 9-Year-Olds

Mix borax, cornstarch, and glue to create custom bouncy balls — a hands-on polymer chemistry experiment with a satisfying tactile payoff.

Blend essential oils to create custom perfume scents — your child learns about top, middle, and base notes while training their sense of smell.

Layer gluey newspaper strips over a balloon to create a unique bowl — the sticky, gooey process is as sensory-rich as the smooth painted result.

Perform classic sensory illusions — the rubber hand trick, the Aristotle illusion, and more — to discover how easily your brain can be fooled.

Walk slowly through a park using all five senses deliberately — then journal observations in a sensory field notebook. Mindfulness meets nature science.

Add iron oxide powder to slime to make it respond to magnets — watch it stretch, reach, and crawl toward a magnet like a living creature.

Make supersaturated sodium acetate solution, then trigger instant crystallization — a tower of warm crystals grows in seconds under your child's fingertips.

Make your own kinetic sand from play sand, cornstarch, and dish soap — then sculpt, slice, and squish this oddly satisfying moldable material.

Slide objects down ramps covered with different textures — sandpaper, foil, fabric — to discover how surface texture affects speed and friction.

Mix baking soda, cornstarch, and food coloring to make paint that fizzes when sprayed with vinegar — outdoor sensory art with a science twist.

Wrap a bar of soap in wool roving and rub with warm soapy water until the wool felts into a soft, textured cover — a meditative, hands-on craft.

Melt gummy bears into stretchy, edible slime your child can pull, twist, and eat — food science meets sensory play in the sweetest way.

Melt glycerin soap base, add colors, scents, and mix-ins, then pour into molds — your child creates custom soaps they'll actually want to use.

Sculpt conductive playdough shapes and wire them with LEDs and a battery — your child builds working circuits they can squeeze and reshape.

Melt beeswax, coconut oil, and flavor extracts to make custom lip balms — a tactile, olfactory craft your tween can use and gift proudly.

Fill a bottle with oil, water, and food coloring, then drop in effervescent tablets to create a mesmerizing lava lamp effect — real density science in action.

Layer honey, dish soap, water, oil, and rubbing alcohol in a jar to create a colorful density tower — then drop objects in to see where they float.

Dissolve borax in hot water, submerge pipe cleaner shapes, and grow real crystals overnight — a slow-reveal science experiment with a dazzling tactile result.

Cook cornstarch and baking soda into silky, bright-white clay that air-dries to a porcelain-like finish — sculpt ornaments, beads, and decorations.

Drop food coloring in milk, then touch dish soap to the surface — the colors explode outward in a swirling, mesmerizing chemical reaction.

Create a real cloud inside a jar using hot water, ice, and hairspray — a visible demonstration of how clouds form that you can reach in and touch.

Melt soy wax, add essential oils and color, and pour into jars — your child creates custom scented candles in a multi-sensory crafting experience.

Blindfold your child and present strong-smelling items — coffee, orange peel, vinegar — for a scent identification game that sharpens olfactory awareness.
