Approximate time needed: 1 hour

NGSS Standards

·         5-PS1-1. Develop a model to describe that matter is made of particles too small to be seen.

·         5-PS1-3. Make observations and measurements to identify materials based on their properties.

·         Review: P.4.6B Students will demonstrate an understanding of the properties of light as forms of energy.

MSCCR Science Standard:

·         P.5.5B.4 Design an effective system (e.g., sifting, filtration, evaporation, magnetic attraction, or flotation) for separating various mixtures. Use an engineering design process to define the problem, design, construct, evaluate, and improve the system.

·         Review: P.4.6B Students will demonstrate an understanding of the properties of light as forms of energy.
