Academic Subject: Science

Grade Level: Year/Grade 7 (Age 11-12)

Lesson Length: 50 minutes

Objectives:

• Students will be able to identify and describe physical properties of substances such as state, boiling/melting point, density, heat/electrical conductivity, color, and magnetic properties.
• Students will learn to collect and evaluate qualitative data on substances using physical properties.
• Students will understand the importance of using physical properties to identify unknown substances.

Materials:

• Various substances for observation: water, oil, vinegar, sugar, salt, sand, iron filings, aluminum foil, etc.
• Access to hot plate/stove top or microwave for heating substances
• Beakers, test tubes or other small containers for holding substances
• Digital scales for measuring mass
• Thermometer for measuring temperature
• Magnet for testing magnetic properties
• Safety goggles and gloves as needed
• Notebook and pencil for recording observations

Procedure:

1. Introduction (5 minutes)

   • Ask students what they remember about physical properties from previous lessons.
   • Explain that in this lesson, they will be collecting and evaluating qualitative data on different substances using physical properties.

2. Demonstrating Physical Properties (15 minutes)

   • Show students different substances (water, oil, vinegar, sugar, salt, sand, iron filings, aluminum foil) and ask them to describe the physical properties of each, such as state of matter, color, texture, etc.
   • Demonstrate how to measure physical properties such as mass, volume, boiling/melting point, density, etc.
   • Discuss the importance of accurate measurement for reliable data collection.

3. Collecting Data (15 minutes)

   • In pairs or small groups, students will be assigned one substance to observe and record physical properties.
   • Students will use beakers, test tubes or other small containers and digital scales to measure mass, thermometers to measure temperature, and magnets to test magnetic properties.
   • Students will record their observations and measurements in their notebook.

4. Analyzing Data (10 minutes)

   • As a class, discuss the data collected and compare and contrast the physical properties of the different substances.
   • Encourage students to identify patterns and relationships between physical properties.

5. Homework (5 minutes)

   • Assign students to identify and describe the physical properties of one substance in their own home and record their observations in their notebook.

Assessment:

• Evaluate students' understanding of physical properties and their ability to collect and analyze qualitative data using physical properties through observation and record keeping.
• Students' homework will be assessed based on their observation and description of physical properties of the substance they selected.
