The Pure, The Mixture, The Unknown – Grade Nine
Description:
This lesson involves classroom discussions, demonstrations
and hands-on laboratory activities about pure substances
and mixtures with a focus on common household materials.
The students will investigate: What is a pure substance?
What is a mixture? How difficult is it to obtain pure
substances? How can one test for purity? What are some
methods for purifying substances? The demonstrations and
labs will introduce students to methods for determining
freezing points, melting points, boiling points, density and,
where equipment is available, conductivity. Students also
will learn to use these data for assessing the purity of
substances.
