Squishy Circuits was developed to teach elementary school children about circuit electricity by letting them build circuits from a PlayDoh-like substance. There are two simple recipes for making the dough: one is conductive and one is insulating. At the simplest level, kids construct a series circuit consisting of one LED, a battery pack, conductive dough, and insulating dough. Learning progresses through parallel circuit construction, motor circuits, buzzer circuits, advanced RGB-LED circuits, and "squishy" animals. All materials are easily acquired, or a kit can be purchased from the website for about $20.

Editor's Note: The Squishy Circuits project team has created high-quality videos to accompany the activities. They cover set-up & preparation, LED calculations, tips for teaching the concepts to small children, and directions for building the more advanced circuits.

3. The Nature of Technology

3B. Design and Systems
  • 3-5: 3B/E2. Even a good design may fail. Sometimes steps can be taken ahead of time to reduce the likelihood of failure, but it cannot be entirely eliminated.

4. The Physical Setting

4D. The Structure of Matter
  • 3-5: 4D/E5. Substances may move from place to place, but they never appear out of nowhere and never just disappear.
  • 3-5: 4D/E6. All materials have certain physical properties, such as strength, hardness, flexibility, durability, resistance to water and fire, and ease of conducting heat.
  • 6-8: 4D/M9. Materials vary in how they respond to electric currents, magnetic forces, and visible light or other electromagnetic waves.
4E. Energy Transformations
  • 6-8: 4E/M2. Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one; 2) mechanically, when two objects push or pull on each other over a distance; 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device; or 4) by electromagnetic waves.
4G. Forces of Nature
  • 6-8: 4G/M4. Electrical circuits require a complete loop through which an electrical current can pass.
  • 6-8: 4G/M5. A charged object can be charged in one of two ways, which we call either positively charged or negatively charged. Two objects that are charged in the same manner exert a force of repulsion on each other, while oppositely charged objects exert a force of attraction on each other.

8. The Designed World

8C. Energy Sources and Use
  • 6-8: 8C/M4. Electrical energy can be generated from a variety of energy resources and can be transformed into almost any other form of energy. Electric circuits are used to distribute energy quickly and conveniently to distant locations.
