Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Topic

Making Crystals with Kids

Objectives

• Understand the basic principles of crystallization.
• Explore how different conditions affect crystal growth.
• Develop hands-on skills with a practical experiment.
• Foster collaboration and teamwork through group activities.

Materials

• Sugar or salt (for crystal formation)
• Water
• Clear jars or cups (one per student)
• String or wooden sticks (for hanging crystals)
• Heat source (such as a hot plate)
• Spoons for stirring
• Paper towels
• Safety goggles
• Thermometers (optional, for measuring temperature)
• Worksheets for observation and data recording

Grade/Age Group

Curriculum Alignment

This lesson aligns with the Canadian national science curriculum, focusing on understanding physical and chemical changes, as well as the properties of matter.

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction	5	Briefly explain the concept of crystals and crystallization. Discuss different types of crystals.
2	Safety Briefing	3	Review safety protocols for handling materials and using the heat source. Ensure all students wear safety goggles.
3	Materials Setup	5	Distribute materials to each student. Assist students in measuring water and adding sugar/salt to create a saturated solution.
4	Heating Solution	5	Use a hot plate to heat the solution until the solute is fully dissolved. Demonstrate careful handling of hot equipment.
5	Cooling Process	3	Allow the solution to cool slightly before placing a string or stick in the jar. Explain how this affects crystallization.
6	Observation	5	Students will observe and record data on their crystal growth over the next few days as they monitor their jars.
7	Conclusion	4	Recap the experiment and discuss what factors might influence crystal growth. Highlight the importance of observations.

Homework

• Each student will write a brief report summarizing their observations of crystal growth over the following week. The report will include diagrams and reflections on what worked well and what didn’t. Reports will be collected and graded at the start of the next class without student presentations.
