These are the specific learning objectives that we cover in Grade 8 Science


D1 Universe and Solar System

Students explain the movements and describe the location composition,
 and characteristics of our solar system and universe, including planets, the sun, and galaxies.

a. Describe the different kinds of
objects in the solar system
including planets, sun, moons,
asteroids, and comets.

b. Explain the motions that cause
days, years, phases of the moon,
and eclipses.

c. Describe the location of our solar
system in its galaxy and explain
that other galaxies exist and that
they include stars and planets.



D2 Earth

Students describe the various cycles, physical and biological forces and processes, position in space, energy transformations, and
human actions that affect the short-term and long-term changes to the Earth.


a. Explain how the tilt of Earth’s
rotational axis relative to the plane
of its yearly orbit around the sun
affects the day length and sunlight
intensity to cause seasons.

b. Describe Earth Systems -
biosphere, atmosphere,
hydrosphere and lithosphere - and
cycles and interactions within
them (including water moving
among and between them, rocks
forming and transforming, and
weather formation).

c. Give several reasons why the
climate is different in different
regions of the Earth.

d. Describe significant Earth
resources and how their limited
supply affects how they are used.

e. Describe the effect of gravity on
objects on Earth.

f. Give examples of abrupt changes
and slow changes in Earth
Systems.


k. Describe the properties of solar
radiation and its interaction with
objects on Earth
