This mini-unit brings your light and optics unit to life through hands-on experiments and activities that teach vocabulary and help ensure concept mastery. The unit includes detailed lesson plans for introductory lessons on transparent, translucent, and opaque materials as well as reflection, refraction, and absorption of light. Included are large vocabulary cards with colorful images for the lesson as well as student vocabulary cards for fun games and practice. Each lesson contains a hands-on experiment with data sheets and templates. I have also included Exit Slips to help in assessing students' learning after the lesson. At the end of the unit is a very helpful Resources Links page.
