This is a 10 lesson unit designed to cover the Australian National Curriculum for Year 5 Chemical Science.
This unit covers matter, states of matter and phase changes. It features a variety of experiments and activities for the students and culminates in a written test.
In this unit, students:
In this lesson, students learn about matter, which is everything around us, and its building blocks. They investigate how atoms make molecules, which make up all the matter in the universe. Everything we can see, touch, taste, or smell is made up of matter.
In this lesson, students learn about the different ways that atoms and molecules can combine, either as compounds or as mixtures, and what the difference between them is. They have the opportunity to make their own mixture (and compound if you choose to do the optional activity)
In this lesson, students talk about the 3 stages of matter, and focused on liquids. They learn that liquids have a fixed volume (cannot be compressed) but no fixed shape, and take the shape of whatever container it’s in.They also learn that there are a few properties (cohesion, viscosity) that are used to compare and sort fluids.
In this lesson, students investigate and explain how solids are different to liquids.
In thi slesson, students learn how matter can change from one state to the other, by adding or removing heat energy. Solids melt into liquids which boil into gases, who can condense back into liquid and freeze into solids.
In this lesson, students learn that almost all molecules move from solid to liquid to gas, but a few rare and unusual molecules can hop from solid to gas, without ever going through a liquid state
In this lesson, students talk about a 4th phase of matter, and some of the new areas of discovery that scientists are exploring.They also learn about what chemists do, and the huge variety of chemistry jobs that are out there making everything from lifesaving medicines, better tasting candy, and trying to solve climate change.
