5 Phenomenal Ideas to Teach Light: Reflection and Refraction in 5th Grade — The Science Penguin

Introducing Independent, Dependent, and Controlled Variables 1. Start off by preparing three pieces of paper with the same ratio of height and width. (This paper is all from the same pack and has the same weight, but I recommend using the same color paper to help make your point.) 2. Fold the papers into the same design for all three. 3. Use the same force to throw the airplanes. Measure how far each one flies. (5.2A)

This foldable provides an engaging way of introducing or revising the concept of variables in scientific investigations. The foldable comes in two versions so you can choose the most appropriate for your context. The first uses the more simple language of; variables that change, are observed and kept the same, while the second introduces the terms independent, dependent and controlled.
