This Thirsty for Gold activity & project also includes:
In the last portion of the six-part unit, teams perform an experiment with gold nanoparticles to determine which sport drink has the most electrolytes. The nanoparticles are used as chemical sensors and fluoresce in different wavelengths based upon cluster size. Pupils develop a basic understanding of how the nanoparticles function using chemistry and physics principles.
- Research how people have used gold and silver nanoparticles in the past
- You need to decide whether the class will synthesize the nanoparticles or whether you will purchase them
- After finishing the activity, assign the poster project to have an end-of-unit assessment
- The handout provides background information that will help the teams
- Directions tell the teacher how to prepare the materials needed to create the nanoparticle
- The gold colloid needed for the activity is expensive
