Phosphorescent Bioplastic Research and Experimentation
"Engage in a lab research to engineer phosphorescent bioplastic, exploring qualitative observations, the electromagnetic spectrum, and the impact of UV radiation. Dive into fluorescence versus phosphorescence and design a novel experiment using reactants like corn starch and phosphorescent powder."

Intro Activity Lab Research to Engineer a Phosphorescent Bioplastic
Definitions Fluorescent - When hit with UV radiation, it absorbs the UV radiation and emits visible light - BUT the emission stops as soon as the UV radiation stops Phosphorescent - When hit by a short wavelength, it absorbs the waves and emits visible light (of a longer wavelength) - The emission may continue after the waves have stopped
Is the powder Fluorescent? Phosphorescent?
Research/Design Problem Today, your challenge is to create a phosphorescent bioplastic using the following reaction scheme: corn starch + water + vinegar + glycerin + phosphorescent phosphorescent powder bioplastic so that the bioplastic is structurally sound and gives off a high phosphorescent. What reactant will you be manipulating? ~ problem step ~
Research Your Reactant Ideas to research: What is your reactant? How is it commonly used? Is it commonly used in baking? If so, why? What does structural integrity mean to you? List your prior knowledge about the reactant.
Hypothesis What is the independent variable? What are the dependent variables? Write a hypothesis that includes the variable and describes how the variables will change. ~ hypothesis step ~
