Engage students in learning about the states of matter, particle arrangements, and properties of solids, liquids, and gases. Identify similarities and differences, understand particle behaviors, and categorize substances. Enhance knowledge with interactive activities and external resources.
E N D
Targets... Today we will be: • Developing our knowledge and understanding of solids, liquids and gases • I can give examples of solids, liquids and gases • I can describe the differences between solid, liquids and gases • Developing our knowledge and understanding of particle arrangements • I can describe how particles are arranged in solids, liquids and gases
Spot the similarity Spot the difference
Similarity: They are all made of the same particles. Hydrogen and oxygen (H₂O) = WATER. Difference: The water particles are in different states. Solid (ice) Liquid (water) Gas (steam)
Think. Pair. Share Split your paper into 3 sections: How many different examples can you think of? (3 minutes) Solids Liquids Gases
How do you know whether something is a solid, liquid or gas? How would you explain to an alien: What a solid is? What a liquid is? What a gas is?
Shape Do solids, liquids and gases have a fixed shape?
Volume Do solids, liquids and gases have a fixed volume?
Flow Do solids, liquids and gases have a flow?
Solid, Liquid or Gas? Sort the substances into solids, liquids and gases. You should be able to explain why...
Solid, Liquid or Gas? Mix some cornflour with water.
Solids, Liquids and Gases • _____________ have a fixed shape. • ___________ and ___________ can change their shape. • _____________ and __________ have a fixed volume. • ___________ can change their volume – they spread out to fill the container. • _____________ cannot flow. • ___________ and ____________ can flow. • Substances that can flow are called _____________.
Solids, Liquids and Gases Marshmallows? Jelly? Sponge?
