5th Grade-Ch. 11 Lesson 4 What are mixtures and solutions

Ch. 11Lesson 4What are

mixtures and solutions?

Problem: What is the easiest way to separate a mixture?

Information: mixtures can be separated by their

different densities-mixtures do not form compounds

Hypothesis:

Activity- Separating a Mixture

mixture all the beads

solution colored water

saturated solution salt water

solute salt

solvent water

mixturedifferent materials are together but do not bond to form compounds

mixturematerials can be separated b/c have different properties

alloymetal that is mixture of elements

ex. brass, bronze

solutionspecial mixture-substances are spread out evenly & do not settle

parts of a solution

solute= smaller amount solvent= larger amount

In a salt water

solutionsolute= salt

solvent= water

saturated solution

contains all the solute that can be dissolved w/out changing temp.

concentrated solution

has so much solute-almost saturated

dilute solution

far from being saturatedsmall amt. of solute

Classify each item as either an element (E), a compound (C), or a mixture (M). Use your textbook & the periodic table to help you identify elements.
