Does it Pour Out? In this activity you will explore how gravitational and electrostatic forces affect water in different situations. Resources: NanoSense; Pour It Out; Structure of Water Visual; Cohesion & Adhesion Jones, M.G., Falvo, M.R., Taylor, A.R. & Broadwell, B.P. (2007). Nanoscale science: Activities for grade 6-12. National Science Teacher Association. 89-94.
Sugar Dissolution Students will be explore surface area to volume effects on sugar to see how surface area compared to volume affects the dissolution of the sugar. Resources: NanoSense; SA/V Ratio
Separation of Mixtures Your objective is to practice important separation techniques to isolate the three components and determine the weight percent of each in the mixture. Resources: Separation of Mixtures;
The BIG Project Students will design an investigation to test their water purification technique on their water supply and present using presentation Software (Powerpoint, Prezi, Google Slides, Keynote, etc.).
Self-Directed Activities - Links, Descriptions and Additional References Students will choose one of the following to explore:
Nanometer Scaling Activity A hands-on activity that has students taking an everyday object and making that nano to visualize how tiny nano is and compare it to everyday objects. Resource: Nanometer Scaling
Optional Activities - Links, Descriptions, and References
Gold Nanoparticles Students will observe the interaction between salt water and sugar water and gold nanoparticles to explore the characteristics of forces between nanoparticles. Resource: Gold Nanoparticles. Adapted by A. Madsen (2015). RGS Summer Workshop. Sponge Absorption Lab Students will determine if natural or synthetic sponges are more absorbent & to use statistical methods to compute and analyze data. Resource: Sponge Absorption Lab
