Integrated Science- Year 2 Sample Flowchart for Concept Instructional Sequence

The Earth is a unique system that supports life within an ever-changing and complex universe.

# IA

Effects of asteroid impacts on surfaces – planets, moons, mass extinctions of life

# How does the structure of the solar system reflect change over time?

• *

Evidence for

existence of planets orbiting other stars (E1g)

Planetary exploration Solar system – structure, scale, and change over time (E1)

Sun, gas and terrestrial planets – similarities and differences (E1a)

# How can Newton’s Laws be used to predict the motion of most objects?

Instruction will include: Solar system components and characteristics Astronomical units; size and distance Place of Earth in the Universe

Conservation of energy

Solve problems of constant and average speed (P1a)

Calculate momentum mv

Perpendicular force change in direction (not speed) of object ((P1g)

Calculate kinetic energy E=(1/2)mv2 (P2a)

Newton’s 1st, 2nd, and 3rd laws predict motion (P1b, P1c, P1d)

• *

Inexact unless object

travels at speed of light or is extremely small (quantum effects) (P1h)

Instruction will include:

motion, mass, inertia, force, acceleration, velocity, constant speed Solar system

How is the movement of objects explained by the laws of conservation of energy and momentum?

Satellite motion

Calculate changes in gravitational potential energy near Earth = mgh (P2b)

• *

centripetal acceleration a- i Universal law of gravitation: effects of gravity (P1e)

Instruction will include:

kinds and transformations of energy
