Matter and Its Interactions: Mystery Mixtures
NGSS Grade 5: Matter and Its Interactions
5-PS1-3 Make observations and measurements to identify materials based on their properties.
Students make observations and use measurements to explore 5 mystery substances in order to identify the substances in mystery mixtures composed of 2 or 3 of the mystery substances. The mystery substances are common household ingredients (salt, sugar, baking soda, cornstarch and plaster of Paris). These substances are observed and tested for powderiness, water reaction, vinegar reaction, and iodine reaction to determine the physical and chemical properties of each of the mystery substances.
The three dimensions addressed are (1) the scientific practices of Planning and Carrying out Investigations, (2) the disciplinary core ideas of Structure and Properties of Matter (3) the crosscutting concepts of Scale, Proportion and Quantity.
This assessment is designed for use after a study unit Matter and Its Interactions
