Tap into the awesome world of electronics with this advanced system of snap-together electric building blocks. Start out by experimenting with colorful light-up circuits as you dive into the basics of electricity. Install a sound module to generate the sounds of police cars, ambulances, or fire engines. Learn the important role resistors and potentiometers (variable resistors) play in an electronic circuit. Use a multimeter to measure invisible voltage and current flowing through your circuit. Investigate transistors in switches and amplifiers to learn how the logical circuits in computers work. Build circuits that use sensors to detect moisture, temperature, and visible light. Incorporate capacitors in your circuits to store and discharge electricity for specific functions

Mistaken for an ancient bison by its discoverers, the Triceratops now has one of the most recognizable skulls on the planet, past and present. Despite its huge, menacing horns, the prehistoric Triceratops often fell prey to the fierce T-Rex. But despite having such a formidable natural enemy, the Triceratops outlasted T-Rex during the great extinction and was one of the last surviving dinosaurs. Nature had built these horned giants to last and now you can build one too! This 4D animal anatomy model has a transparent cutaway to show internal structures. 46 fully detachable organs and body parts. Highly detailed assembly kits are educational and collectible. Quality finished with hand painted parts. Includes a display platform and illustrated guidebook. Remove the dinosaur's bones and organs and replace them as you learn the physical anatomy Comes with display platform and illustrated assembly guide and description of the anatomy along with some fun Q and A to test your knowledge Fine, detailed sculpting with hand-painted parts.
