Who is this Objectives 1 To define mass

Who is this?

Objectives 1 • To define mass and energy 2 • To learn about the physical states of matter • To learn about transformations of state 3 • To interpret and produce particle model diagrams to describe states and transformations 4 • Reinforce the particulate model of matter

Outcomes You should be clear whether you are talking about matter or energy You should know the features of solids, liquids and gases and what causes them to change. You should be able to show using models your understanding of the particulate nature of matter.

Place these words/phrases in the correct columns (they are mixed up) Matter Energy Fire Light Liquids Made of particles Gases Contains bonds Sound Solids Travels as waves Heat Atoms Wood Power Uranium fuel electricity

List things which are energy not matter

Now we’ll forget about them for the time-being because they’re Physics Name Solids Liquids Gases

Investigate What are the features of solids, liquids and gases? Features Solids Liquids Gases

Particle models http: //www. youtube. com/watch? v=NTEyq. YNIe. A http: //www. youtube. com/watch? v=yn. Uso 6 r. J 0 r. E

On the board Draw particle models for liquids and gases Discuss their features. Why does heat travel more slowly in a gas?

Act out particle models What causes the change? Draw your own particle models of solids, liquids and gases Two more important terms: fluids and plasmas

Changes of state Solid to liquid Liquid to gas Liquid to solid Gas to liquid Solid to gas Produce particle models that show these changes. (they’re better with happy smiley faces) I suggest you do three pictures for each one. What it is like at the beginning, half way through and at the end. You must show bonds where present and indicate movement.
