What every student should learn about Physical Sciences

• What is everything made of?(How do particles combine to form the variety of substances one

observes?)

• Why do things happen?– What force caused that action?

(How can one predict an object’s continued motion, changes in motion, or stability?)

• What is energy?(How is energy transferred between objects or systems?)

Is it Matter, Energy or a Force?

Particle Nature of Matter

2nd grade 5th gradeMatter is Matter is visibleSolids and or too small toLiquids be seen and

includes Air(gases)Matter is conserved.

Why Do things happen?

What force cause that action?Contact Forces Force at a distanceCollisions GravityFriction MagnetismTension ElectrostaticNormal (material)

Newton’s Laws Describe Motion

2nd 5thForces are: Forces include:Pushes Contact Forces Pulls pushes pulls collisions

Collisions Forces at a Distancegravity magnetism

Forces can be measured

Newton’s Laws Describe Motion

8th HSForces are: Motion is described by Balanced Newton’s LawsUnbalancedand cause Accurate predictions of Motion forces and motion can beStability made mathematically.

Energy is not a thing!

Energy makes Particles move & CollideForms of Energy Energy Transfer ConservationMotion motion-motion never destroyed!Heat Energy TransformationLight form – different formSoundElectricalChemical

Energy = Motion

2nd 5th

Energy is: Energy is transferredHeatLight Energy is transformedSoundMotion Energy changes matter(chemicals/food)

E= MC2

Energy at the atomic levelEnergy is Conserved
