Overview

During these lessons students will explore particle theory by investigating the properties of solids, liquids and gases, by investigating changes in state and by understanding density. 

Students are learning to:  

• know how matter responds when its temperature changes

• understand why matter changes when its temperature changes

• be able conduct a scientific investigation

• be able to make observations and relate findings from investigations to particle theory.

Success criteria 

• I have communicated my understanding of how and why matter changes when there is a temperature change.

• I can follow a sequence of instructions to undertake an investigation.

• I can process information from observations and identify relationships.

Outcomes:  

• SC4-6WS follows a sequence of instructions to safely undertake a range of investigation types, collaboratively and individually  

• SC4-7WS  processes and analyses data from a first-hand investigation and secondary sources to identify trends, patterns and relationships, and draw conclusions  

• SC4-8WS selects and uses appropriate strategies, understanding and skills to produce creative and plausible solutions to identified problems

• SC4-16CW describes the observed properties and behaviour of matter, using scientific models and theories about the motion and arrangement of particles

Students will explore the particle theory and learn new terminology by undertaking investigations on liquids, solids and gases.

• Activity 1 - Particles like to stick together

• Activity 2 - Temperature and particle movement in liquids

• Activity 3 - Temperature and particle movement in solids

• Activity 4 – Temperature and particle movement in gases

Students will investigate changes in state by completing a series of experiments. 

• Activity 1 - Evaporation and boiling

• Activity 2 - Condensation

• Activity 3 - Freezing

• Activity 4 - Melting

Students will explore density by completing calculations, by graphing data and through an experiment that looks at the effect of temperature on density. 

• Activity 1 - Calculating density

• Activity 2 - Temperature and density
