Gumdrop Molecules Activity Name: ____________________________ Period: ________ INTRODUCTION: The purpose of this investigation is to make observations about different types of chemistry materials in an effort to develop your own definitions of what an element, compound, and mixture are. Work in teams of 3-4…each team will need one bag of pre-made gumdrops (with 6 individual bags inside). 1. Make observations about the contents of each bag…draw and label what you see, paying special attention to amounts, arrangements, and colors. Please use colored pencils for your observations. Please DO NOT open and/or eat the gumdrops!!! Sodium (Na): Element Oxygen (O): Element Salt (NaCl): Compound Rust (Fe2O3): Compound Salt Water (NaCl + H20): Mixture Air (O2 + N2 + CO2): Mixture 2. Describe two general observations, patterns, and/or trends you noticed when looking at the different materials… _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ More on back 3. In the space below, use your observations and thoughts to describe the difference between elements, compounds, and mixtures. _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ 4.
