• Abstract: A car propelled by the reaction between lemon juice and baking soda has more in common with rockets and jet aircraft than one might think. In this video segment adapted from ZOOM, two cast members demonstrate the power of rocket-propelled vehicles and how to exploit the force produced by the carbon dioxide gas. Grades 3-8.

  US.MCREL.K-12.sci.8
  Standard 8. Understands the structure and properties of matter
  US.MCREL.6-8.sci.8.8
  8. Knows that substances react chemically in characteristic ways with other substances to form new substances (compounds) with different characteristic properties
  US.MCREL.K-12.sci.9
  Standard 9. Understands the sources and properties of energy
  US.MCREL.6-8.sci.9.6
  6. Knows that most chemical and nuclear reactions involve a transfer of energy (e.g., heat, light, mechanical motion, electricity)
  US.MCREL.K-12.sci.10
  Standard 10. Understands forces and motion
  US.MCREL.6-8.sci.10.4
  4. Understands effects of balanced and unbalanced forces on an object's motion (e.g., if more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude; unbalanced forces such as friction will cause changes in the speed or direction on an object's motion)
