PS4 C: Information Technologies and Instrumentation

# data[].attributes.body
END OF 2ND: People use senses to learn about world around them. People use different devices to communicate long distances.
END OF 5TH: Lenses can be used to make lots of things. Digitized info can be stored for future recovery.

# data[].attributes.body
END OF 2ND: Objects can only be seen with light. Hot objects give off light. Light can go through some objects.
END OF 5TH: Light travels through space to earth. How light reflects off of surfaces into our eyes.

# data[].attributes.body
END OF 2ND: Waves are regular patterns of motion. They can be made of water.
END OF 5TH: Waves differ in amplitude if they have the same hight. They can cancel or add to each other.

END OF 2ND: Friction, friction causes warmth.
END OF 5TH: Produce energy=conversion of stored energy to desired form for use.

PS3 C: Relationships between Energy and Forces

# data[].attributes.body
END OF 2ND: Bigger push/pull makes things go faster. Faster speeds in a collision cause bigger change.
END OF 5TH: Contact forces transfer energy to change objects' motions. Magnets have force on other magnets.

PS3 B: Conservation of Energy and Energy Transfer 

# data[].attributes.body
END OF 2ND: Sunlight warms earth's surface.
END OF 5TH: If there is movement, light, sound, or heat there is energy. Energy can be transferred between objects.

# data[].attributes.body
END OF 5TH: The faster an object if moving the more energy it has. Energy can be moved from place to place.

PS2 C: Stability and Instability in Physical Systems

# data[].attributes.body
END OF 2ND: An object often has multiple forces on it.
END OF 5TH: A system can change as it moves in one direction, shifts back or forth, or goes through cyclical patterns.

# data[].attributes.body
END OF 2ND: When objects collide, they push on one another and can change motion or shape.
END OF 5TH: Objects exert forces on one another. Some forces do not require contact.

# data[].attributes.body
END OF 2ND: Objects push/pull each other when they collide. Push/pulls can have different directions or strength.
END OF 5TH: Each force has a strength and direction. An object at rest stays at rest unless acted upon by another force.

END OF 2ND: Heating or cooling changes substances. Sometimes these changes are reversible.
END OF 5TH: When substances mix, a new substance is formed.

PS1 A: Structure and Properties of Matter

# data[].attributes.body
END OF 2ND: matter exists and can be solid or liquid (depending on temperature) and it can be classified by observable properties.
BY END OF 5TH: Matter can be divided into particles too small to see (but it still exists) and amount of matter is conserved when it changes.
