Making a bottle rocket : G5 + G6

To Infinity and beyond!!!

As part of our study of chemical reactions in November, we looked at how chemical reactions can be used to propel rockets into space by harnessing the creation of gas. We made our own rocket using sodium bicarbonate (baking soda) and vinegar, the vinegar reacts with baking soda to create carbon dioxide gas. Pressure, due to gas, builds inside the bottle until finally the bottle cork is pushed out and the bottle rocket is launched into the air. Unfortunately, we didn’t manage to catch the rocket’s movement on camera, but you can see our rocket launch preparation and aftermath. The students were very excited to see our rocket launching.

  • Students learned that chemical reactions not only happen all around us, but that they can also be used as tools, such as in a rocket launch.
  • Students learned that gas is produced because of a chemical reaction when sodium bicarbonate and vinegar are mixed.
  • We saw that, as we have studied earlier this month, gas takes up space even if we can’t see it. This was evident through the pressure pushing the cork from the bottle.
