Our four-sided friction block demonstrates how frictional characteristics affect the force required to move a stationary body. Offering four different friction surfaces, the block can be used to teach numerous concepts involving friction, including force and energy, gravity, static friction, and kinetic friction. Comes with a hook on one side for towing and a threaded brass post allows for easy addition of slotted masses (sold separately) to all four sides.

Material: sandpaper, vinyl, paper (Cellulose), wood (Steam Beech).

Dimensions: 2” x 2” x 2”

All you need to do is fill the reservoir with water and this clock starts working. Because the water is an electrolyte, it allows two metal pieces to act as a conventional battery. By adding a bit of lemon juice, you can help to enhance this process. The only maintenance required is to change the water periodically.

Demonstrate the heart of Cell Phone and Wireless Communication modules! This clever demonstration shows how your voice can be sent on a light beam through the air or through optical fibers. This is an important concept since all smart phones and computer systems send digitized, encoded radio signals to the nearest towers. This circuit, together with a microphone transforms your voice into vibrations of the LED light. By pointing the light at a solar cell and mini-amp you can transform the blinking light back into a high quality sound. Bias Circuit Board includes superbright LED and 9 volt battery.
