This is our second one pound gummy bear reacting with potassium chlorate. For this video we filled the gummy bear with more potassium chlorate resulting in a longer reaction.
Potassium chlorate is a chemical that reacts violently with sugar. In this video, we filled a one pound gummy bear with potassium chlorate and used a magnesium strip to provide heat to begin the reaction.
Volume is a measurement of the amount of space that an object or substance takes up. In this video, we see how volume of a liquid can be measured using a graduated cylinder. We also look at how the displacement of a solid object can be used to measure its volume.
This year, our STEM Club was able to do science demonstrations at the Uptown Wadesboro Fall Festival. Several students used calcium carbide to explode individual pumpkins, and we finished with a chain reaction explosion of eight pumpkins.
