Develop their senses and encourage science exploration with this set of 4 sturdy, clear tubes.In the world of sense-centric scientific exploration, these Sensory Tubes stand alone – literally! The clear tubes are freestanding, which means that students can go “hands-free” while investigating all things bright, noisy, aromatic or just plain cool. The tubes feature dual openings and 2 solid lids for each (8 lids in total), plus an additional four vented lids. This lets children explore their sense of smell or secure small creatures for observation. The lids easily twist off and on, and solid lids hold liquid securely inside. This leads to astounding (and mess-free) moments of discovery. Who knew a tactile learning set could be so…. untouchable? Fill the tubes with handy everyday items to enhance students’ sensory experiences. The possibilities are endless. This is the perfect open-ended resource for the young ones to explore the world around them without boundaries. The sensory tubes come empty and measure 30 cm long x 5 cm in diameter. Hand wash the sensory tubes with warm soapy water after use. The tubes come with an instruction guide to give you some ideas of materials to fill the tubes with, to get you started. Find out what they sound like, smell like, feel like, look like.Tubessuitable for children aged 2 years and up.
