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}

Lesson plan

Topic

Rate of Dissolution: Surface Area with Different Sugars

Objectives

• Understand the concept of dissolution and the factors affecting it.
• Investigate how the surface area of sugar affects the rate at which it dissolves.
• Conduct a hands-on experiment to observe the differences in dissolution rates.
• Analyze and record findings in relation to hypotheses.

Materials

• Different types of sugar (granulated, powdered, and sugar cubes)
• Measuring spoons
• Clear plastic cups (32)
• Water
• Stopwatch or timer
• Stirring sticks
• Ruler (for measuring sugar cubes)
• Worksheets for data recording
• Safety goggles (optional)

Grade/Age Group

• Year/Grade 7

Subject

• Science

Class Size

• 32 students

National Curriculum

• TEKS 7.6W

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Dissolution	5 minutes	Briefly explain dissolution and its importance in science. Discuss surface area and its effect.
2	Hypothesis Formulation	5 minutes	Divide students into groups to formulate hypotheses about how different types of sugar will dissolve.
3	Experiment Setup	10 minutes	Distribute materials to each group. Demonstrate how to set up the experiment and the proper measuring of sugar and water.
4	Conducting the Experiment	15 minutes	Students perform the experiment, timing each type of sugar dissolution and recording observations.
5	Data Analysis	5 minutes	Groups analyze their data, comparing dissolution times and discussing whether their hypotheses were correct.
6	Wrap-up and Discussion	5 minutes	Bring the class together to discuss findings, answering any lingering questions. Summarize key takeaways from the lesson.
7	Homework Assignment	5 minutes	Assign a worksheet requiring students to write about factors affecting dissolution and their experiment results, to be submitted the next lesson. Check homework without presentations.

Homework

• Complete the worksheet reflecting on the experiment results and relating them to the factors affecting dissolution. Finish the assignment in class time or at home, to be turned in during the next lesson without presentations.
