This anatomical chart depicts the anatomy and pathology of the hand and wrist in bright colors.

Real-world climate and sustainability investigations, powered by the popular BBC micro:bit!

Ideal for studying rotational dynamics.

Used to investigate wavelength in air.

Play sand provides tactile and sensory stimulation necessary for the development of a child's imagination, hand-eye coordination, and fine motor skills such as shoulder stability, forearm rotation, wrist control, and hand strength. Play sand also encourages creativity, visualization and social interaction.

Measure grip strength, pinch strength, and muscle fatigue wirelessly with Go Direct® Hand dynamometer.

Hand crank centrifuge capable of holding 4×15 ml tubes, includes tubes for immediate use.

Codeable, 3D-printed robotic hand for interactive STEM learning.

A unique manufacturing process makes these models exceptionally lifelike. All feature a durable, yet flexible, rubberized material applied over molded plastic bone structures allowing for flexion and extension, inner and outer rotation, adduction and abduction, and other realistic movements of the joints.
