The Particle Theory and State of Matter in year 8 Science

A powerpoint that undergoes particle theory and states of matter in year 8 chemistry

1. Introduction to Chemistry & the Particle Theory

2. When behaviours are exhibited that fall below the school-wide expectations, this will be the flow chart that will be followed.

3. WALT: Textbook: Pages 299-300 Key terms: Solid, liquid, gas, condensing, freezing, melting, evaporating, sublimation. Explain how the properties particle of the particle model can be used to identify different states of matter. Describe the five basic principles of the particle model theory. WILF : Define the particle theory. Identify different states of matter based on particle composition.

4. THINK-PAIR-SHARE Discuss the chemistry concepts you learnt about in year 7.

5. You will complete a written exam in week 5 and 9 . This will include multiple choice and short answer questions. It is important that you are reviewing all concepts learnt throughout the term to ensure you see success in your final assessment. Assessment

6. Chemistry Pre-Assessment Complete the pre-assessment to the best of your ability. REMEMBER- This helps ME help YOU!

7. Unit 2: Chemistry Goal Setting Today, you will set a goal around your achievement in term 2 for science. The areas shown in pink boxes on your action plan will be completed today, while others will be completed at the end of the term. You will need to reflect on last term and the behaviours you need to demonstrate to achieve your goal.

8. The Particle Theory of Matter The Particle Theory also explains how matter behaves and interacts with different matter. WILF – Define the particle model of matter. The Particle Theory of Matter attempts to explain the properties of: Gases, liquids and solids Solutions Changes in state

9. Matter WILF – Describe different types of matter Matter is a substance that has mass and takes up space.

10. Principles of the Particle Model All matter is made up of particles. The particles are always moving The more energy (heat) particles have, the faster that they move. All particles of a substance are the same. There are attractive forces between particles. WILF – List the 5 principles of the particle model of matter

11. Types of Matter Types of matter Pure Substances Mixtures Element Compound Homogeneous mixture Heterogeneous mixture Definition Diagram Example WILF – Describe different types of matter Use the next 2 slides to complete the table below.

12. Type 1: element cannot be broken down in to simpler substances. Examples: oxygen or hydrogen Type 2: compound contains two or more elements. Examples water - H 2 O or sugar - C 6 H 12 O 6 WILF – Describe different types of matter Types of Matter- Pure Substances Pure substances only have one type of molecule.

13. Types of Matter- Mixtures Type 1: homogeneous this mixture is uniform (the same) throughout. Examples: white vinegar, orange juice without the pulp Type 2: heterogeneous this mixture is not uniform throughout and can be separated. Examples: pizza, vegetable soup WILF – Describe different types of matter Mixtures have more than one type of molecule

14. Activity: Classifying Mixtures Classify the following mixtures as homogeneous or heterogeneous. Salt and water Pizza Garbage Air Nitrogen Toothpaste Sand Carbon dioxide WILF – Classify different types of mixtures
