Properties of Matter for 5th Grade: Mixtures and Solutions is a complete unit on identifying materials based on their properties. Students will learn about the properties of solubility and conductivity and will plan investigations. Students will also investigate suspensions and colloids. This resource includes six investigations, a slide show on planning an investigation and identifying variables, a nonfiction reading passage on and another nonfiction reading passage on . This resource used phenomena to engage students and has great response pages and lab pages. This unit also includes a multiple-choice quiz. The materials for the labs are easy to find household materials. Students will love this engaging unit!
There are many types of mixtures. Students will learn about suspensions, colloids, non-Newtonian fluids, alloys, solutions, homogenous mixtures, and heterogeneous mixtures. Students will learn that suspensions will eventually separate. In these six investigations, informational text passages, and lessons students will learn about the properties of matter.
This resource meets the standards from the strand Structure and Properties of Matter NGSS 5th grade NGSS 5-PS1-1. and NGSS 5-PS1-3. And also Utah SEEd 5.2.1 and 5.2.2
NGSS 5-PS1-1. Develop a model to describe that matter is made of particles too small to be seen. [Clarification Statement: Examples of evidence could include adding air to expand a basketball, compressing air in a syringe, dissolving sugar in water, and evaporating salt water.] [Assessment Boundary: Assessment does not include the atomic-scale mechanism of evaporation and condensation or defining the unseen particles.]
5-PS1-3. Make observations and measurements to identify materials based on their properties. [Clarification Statement: Examples of materials to be identified could include baking soda and other powders, metals, minerals, and liquids. Examples of properties could include color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility; density is not intended as an identifiable property.] [Assessment Boundary: Assessment does not include density or distinguishing mass and weight.]
Utah SEEd 5.2.1
Develop and use a model to describe that matter is made of particles on a that is too small to be seen. Emphasize making observations of changes supported by a particle model of matter. Examples could include adding air to expand a balloon, compressing air in a syringe, adding food coloring to water, or dissolving salt in water and evaporating the water. The use of the terms atoms and molecules will be taught in Grades 6 through 8. (PS1.A)
Utah SEEd 5.2.2
Ask questions to plan and carry out investigations to identify substances based on of their properties. Emphasize using properties to identify substances. Examples of properties could include color, hardness, conductivity, solubility, or a response to magnetic forces. Examples of substances could include powders, metals, minerals, or liquids. (PS1.A)

In this resource Students will love being detectives and trying to determine the mystery substance based on its properties! Students will conduct four different investigations to determine the properties of matter and eventually to determine the identity of the mystery substance. Students will also learn about lab safety.
