Who doesn't love the feeling of running your fingers through a soft pile of sand? Encountering new or strange textures has a way of fascinating big and little kids alike. When something inspires a child's curiosity, what's her first instinct? To touch it! Set up a sensory table for a fun, tactile activity. You can even sow some seeds of scientific wonder and make some Oobleck, a magical, goopy mixture that's both solid and liquid!
