PHYSICS: Today was the last of the applications of lenses and refraction. I love it when you get to see how physics crosses over into other disciplines of science – from physiology with myopia and hyperopia and how lenses can help, to how microscopes and telescopes work. And also ever important to know – why is sky blue, and why are sunrises and sunsets orange?!?

Speaking of lasts – the LAST chapter test is Tuesday!! What should you practice? Application of concepts, ray diagrams with mirrors and refraction through a transparent medium and lenses, and problems. Hey, here’s something to think about… can something really disappear into thin air? How??
