Transcript of Year 8 davinci
OUTCOMESStudents will define what is matter.Students will be able to list methods that scientist use to investigate atoms.Students will
OUTLINE1. Quick review of elements and
compounds2. Everything is made of matter3. What is matter?4. How do we see it , how do we
know its there?
HOMEWORKWhat did they believe before they developed the particle theory?
DO NOWWhat is the smallest things you’ve ever seen?
Do NowWhat is the smallest thing you’ve
ever seen?
1. Quick Review List as many elements as you can think of in 60 sec.
Write their names or symbols
How many did you get?• Ask Pierre to do this
List as many compounds as you can in 60 sec How many did you get ?
• Pierres number
2. Everything matters What do we know That there are things called Atoms
They are made of even smaller parts protons, electrons, neutrons
Where are these atoms? EVERYWHERE!
All these elements, compounds and molecules have mass
KEY CONCEPT
Matter is anything that takes up space (has volume, and can be
weighed.
Can we see Atoms http://www.youtube.com/watch?v=yqLlgIaz1L0
What element were they looking at?
Platinum Pt
What are the little bumps on the element?
What is disassociation of the particles ?
Why is it important to look at atomic structure?
How can we use this? Helps us to understand the world around us.
Matter describes anything that has mass. The universe is made of matter, which in turn is made of particles.
How these particles behave determine the characteristics of the substance.
OUTCOMESStudents will describematter in terms of particles that are constantly moving. Students will apply the theory of particle theory to the world around them.
OUTLINEWhat is the theory behind this?
Particle theory
How do we use this
HOMEWORK
Why does the handle of a metal spoon heat faster than a wooden one?
DO NOWTalk with your neighbour about what you discovered with your homework
Review Last lesson we understood that
Matter is everywhere
Particles interacting gives substances their characteristics
Particle theoryHistory of Particle theory.
Video on particle motion in real life situation (mercury / lead)
What is particle motion Main points
How do we describe matter Physical state (solid, liquid, gas) Colour- Is it oderless, flowery, spicey, neasuating Clarity- Clear, Cloudy, opaque Luster- Shiny, dull Form- Regular (crytalline), Irregular (amorphous) Texture- How does it feel, fine, course, smooth, waxy Hardness- Can it be scratched easily (scale 1-10) Brittleness- is it flexible or brittle Malleability- can it be bent and folded Ductility – can it be stretched out into long wires Viscosity- does it flow? Viscous or non viscous.
Practicum- describing matter In groups you are to go from table to table describing
the matter on the table using your new scientific vocabulary.
Write your answers in the table provided for you.
OUTCOMESStudents will be able to define the three states of matter.Students will be able to explain how matter is transformed.
OUTLINEWhat are the three states of matter?Discuss the movement of particles from last lesson. Worksheet labellingHow do we change the state of matter?
HOMEWORK DO NOW
Types of matterThere are three main types of matter
What are they?
Solids
Liquids
Gases
PropertiesStates of matter
Can be weighed
Occupy space
Fixed Shape Fixed Volume
Can be compressed
SOLIDS
yeS
YES YES YES NO
LIQUIDS YES YES NO YES NO
GASES YES YES NO NO YES
Discuss the particle theory
What elements are liquids at room temp
Experiment particles and models
OUTCOMESStudents will be able to explain expansion and contraction in terms of the particle model
Students will produce diagrams that represent how particles expand and contract.
Students will relate the changes in the particle movement to the physical changes of the material.
OUTLINE1. Expansion and
contraction2. How do we relate this to
our particle model?
