Encourage teamwork or independent discovery as students snap the electric building blocks together to create more advanced circuits. Applying the knowledge learned while creating these circuits helps students better understand the electronics they use every day. Experiment with various resistors to learn how they affect electric currents. Learn how switches and amplifiers power computers. Create a water or temperature sensor. From an assortment of resistors to lights and even a microphone, 141 pieces include all the components needed for experiments and 168-page manual details instructions; see manual for full contents list. 9V battery required (not included). Recommended for Elementary and up.
