SOLUTIONS AND SOLUBILITY WORKSHEET AND LAB SHEET

Teach solutions and solubility by challenging your students to design and do their own experiments to investigate if temperature and surface area affect how fast sugar dissolves in water. This resource has been designed to help students develop and build their 21st century skills which includes collaboration, experiment design, critical thinking, data analysis and representation and observation. **Check preview for sample sheets and key

What’s included in this resource?

A complete Power Point Presentation ( with notes on all slides for the teacher )
Solutions Labsheet ( including the advance and general versions)
Post Lab Worksheet ( for students to plot a graph)
Answer Keys
Teacher Guide ( with tips and all guidelines)
Introduction:

Students are introduced to the topic of solutions via the PPT slides in this resource. This provides students the background and help them understand the meaning of solutions in chemistry terms, their examples, types and how to they are made (i.e solute + solvent= solution)

Part 1:

Students are presented with two driving questions;

a) Does increasing or decreasing the temperature affect how fast sugar dissolves in water?

b) Does increasing or decreasing the surface area affect how fast sugar dissolves in water?

They are challenged to design and carry out their own experiments to investigate these questions. All information and guidelines are included in the PPT for the teacher in cluding the post lab activities.

Part 2:

In this part, students are provided with data on the temperature vs solubility of three different types of salts. They use the data to plot a line graph and complete some related questions. Note: I have included a great way to further increase students’ engagement and curiousity during this part in the PPT.

Materia List per group ( * = can be shraed with other groups)

two beakers
sugar granules*
hot water*
cold water*
digital weight balance *
spatula (or glass rod)
Sugar cubes*
All materials are relatively easy to obtain

GRADE LEVEL:

Grades 7 to 9

Try this student-centered lesson on solubility vs temperature and surface area and see your students enter their scientist mode. It’s always beautiful to observe their involvement and engagement when the lesson feels like their own. I believe this resource will prove valuable to you for many years to come as it has in my own class.
