TEKS Based Lesson Plan
Subject: Chemistry
Weeks: 4th Nine Weeks Group 1
Unit of Study: Solutions, Acids and Bases, and Oxidation/Reduction
Essential Questions:
• How can solubility be investigated?
• What are the differences between unsaturated, saturated, and supersaturated solutions?
TEKS/Essence Statements:
• 10 (E) distinguish between types of solutions such as electrolytes and nonelectrolytes and
unsaturated, saturated, and supersaturated solutions;
Critical Skills/Postsecondary Goals:
This section needs to be completed based on the students in your class.
Instruction/Classroom Activities:
Small Group Instruction:
•
•
Review and introduce new word wall words: unsaturated, saturated, and supersaturated.
**optional flashcard activity from previous lessons.
Activity: Sugar in Iced Tea: if you only sprinkle about a third of a packet of sugar and stir it until
it dissolves in your iced tea, is it still possible to add more? (unsaturated solution--capable of
having more solute dissolved in it) Is there a point when you've added so much sugar - you can't
add any more? What happens if you try? (saturated solution--has the maximum amount of solute
dissolved in it; any additional solute added will settle, undissolved, to the bottom) What if we
added a whole lot of sugar and dissolved it while the tea was still boiling hot, before we added the
ice. Could the hot tea contain more sugar than the same volume of cold tea? (yes) Would it stay in
solution even after we add ice? (yes--supersaturated solution)
Stations/Centers:
• Word wall activities
• Online Lab: How is solubility of a compound determined?
http://www.glencoe.com/sites/common_assets/science/virtual_labs/PS15/PS15.html
• Hands on activity: mixing other concentrations/solutions with water, or sugar, to see the
differences in solubility. (Ex. Any preferred juice concentrate with water. Kool aid, sugar, and
water)
Individualized Communication Planning: This section needs to be completed based on the
individualized communication needs of the students in your class.
