Structure and Properties of Matter

Structure and Properties of Matter

Students explore atomic and molecular structure. Students build atomic and molecular models. Students also study properties of various types of matter including conductivity and reactivity. Students determine the thermal and electrical conductivities of different materials using thermometers and multimeters. Equipment includes atomic and molecular model kits, thermometers, hair dryers, material sample cylinders and cubes, scales, beakers, and multimeters.

Lesson 1: Atoms and Molecules

Students learn about basic chemistry, including atomic and molecular structure and the periodic table. Students build atomic and molecular models.

Lesson 2: Properties of Matter

Students learn the difference between physical and chemical properties. They then study various physical properties of matter and observe physical properties in the lab. Students write a report describing their observations.

Lesson 3: Reactivity

Students learn about the different types of chemical reactions and how different substances react with one another. They perform and classify simple chemical reactions in the lab.

Lesson 4: Conservation of Mass

In order to verify the concept of conservation of matter, students combine materials to create a chemical reaction to form a third distinct material. Students measure the total amount of each of the original materials and the new material. Students also compare the properties of the new material to the properties of the original materials.

Lesson 5: Conductivity

Students learn about thermal and electrical conductivity and why some materials are conductors and some are insulators. Students determine the thermal and electrical conductivities of different materials using thermometers and multimeters.
