A dramatic, extreme endothermic reaction

Don't leave endothermic reactions out in the cold—showcase them with this impressive demonstration! Students observe how a reaction between 2 solid compounds absorbs heat from its surroundings and freezes a beaker to a wooden block. They’ll be amazed to see the beaker frozen so tightly that lifting the beaker raises the block.

Make predictions and construct particle-level explanations

Students not only observe this remarkable demo, they actively participate in it. From making a prediction of what will happen based on prior knowledge to using words and pictures to explain the reaction on a molecular level, students will move from the big picture to hard science. Big Picture Questions solidify the concepts, and real-world and career applications of endothermic reactions bring meaning to the demonstration.

This demo requires approximately 10 min of classroom time, and materials in the kit are sufficient for the demo to be performed 6 times.
