TABLE OF CONTENTS - Lindbergh School District

Concept D: Chemical reactions involve changes
in the bonding of atoms with the release or
absorption of energy
Concept E: Nuclear energy is a major source of
energy throughout the universe
Concept F: Energy can change from one form to
another within systems but the total amount
remains the same
Scope and Sequence – Energy Transformations
Not assessed at this level
Not assessed at this level
a. Identify the different energy transformations
that occur between different systems (e.g.
chemical energy in battery converted to
electricity in circuit converted to light/heat
from a bulb)
T
a. Students will provide examples in the
classroom of ongoing chemical
transformations.
a. From examples, students will explain the
conversions of energy occurring and trace
the flow of energy.
b. Recognize that, during an energy
transformation, heat is often transferred from
one object (system) to another because of a
difference in temperature
T
b. Students will measure and quantitatively
compare the heat changes involved in an
energy transformation. (1.2; 1.3; 1.6; 1.8;
2.4; 3.5)
b. From examples, students will explain the
conversions of energy occurring and trace
the flow of energy.
c. Recognize that energy is not lost but conserved
as it is transferred and transformed
c. Students will trace the flow of food energy
in a food web. They explain where the
seeming ‘losses’ in the food energy go.
c. Students will explain the path of energy in
a complex food web. What is the source
of that energy Why does the energy
‘seem’
