GETTING READY FOR INSTRUCTION
Performance Indicator(s):

In a graph organizer, explain how you classified the properties of substances
before and after mixing. In a short summary, evaluate and explain what
influence the properties of substances had on each after mixing.

Key Understandings and Guiding Questions:
Changes made to substances may affect their properties.
— Describe the advantages and disadvantages of causing a substance to
change?
— What properties help you to separate different substances in a mixture?
Actions over time can create measurable change
— How does mixing affect the dissolving of ingredients?
— Why does dissolving take time to be noticeable?

Vocabulary of Instruction:
mixture magnetism ingredient
matter ingredient dissolve
physical properties substance heat resistant

Background Information:
A mixture consists of two or more substances that do not react chemically. One of
the most important concepts to relay about mixtures is that simple mixtures can
be separated by mechanical means. The ingredients in mixtures do not form new

Unit: 1 Lesson: 2

physical properties. Instead, the ingredients of a mixture retain their original
properties. Mixtures can be separated by physical means such as manual
separation, by weight, use of magnets, filtering, and evaporation. Solutions are
mixtures that are the result of a solute dissolving in a solvent. The solute is the
substance that is dissolved in another substance. Solutes can be solids, liquids,
and gases. The solvent is the substance that dissolves another substance. Water is
commonly used as a solvent. It is important for the student to learn what
substance is being dissolved and what substance is doing the dissolving.

the picture of the Mini-board Picture Handout as
an example.


1. Ask:
What was your conclusion?
Was your hypothesis correct?
What substance dissolved?
Why do you think the hot water allowed
the sugar cubes to dissolve the fastest?
Help students understand that the more energy
that is in water the faster the molecules are
moving and the faster the sugar will dissolve.
2. Ask:
What properties do we now know about
hot water?
Why does dissolving take time to be
noticeable?
What influence did the properties of each
substance have on each other after mixing?
Direct the students to conclude that adding
water to the sugar caused the sugar to dissolve
and a mixture of uniformity (homogenous) was
created which is a solution.
3. Once you have a discussion with the groups
allow the groups to talk to their peers about
their results, hypothesis, and conclusion.
