Enroll in Science 7 with Dolphin STEM Academy

Course Overview

Science is the study of the natural world. It relies on investigations and evidence to
describe the natural events that occur around us. Science 7B is about matter and
energy. It discusses chemical changes that occur in matter, and it teaches how to
identify different forms of energy. The course also covers force fields and the factors
that affect their strength. In the first unit, you’ll apply the law of conservation of energy to
the products and reactants in a chemical reaction. In the second unit, you’ll be
introduced to gravitational, electric, and magnetic force fields. In the third unit, you’ll
learn more about energy transformations in objects and systems as you study kinetic
energy, potential energy, and thermal energy.

Course Goals

By the end of this course, you will be able to do the following:
Compare properties of reactants and products to determine whether a chemical
reaction has occurred.
Develop a model to show that atoms are conserved in chemical reactions.
Describe energy changes that occur during a chemical reaction.
Describe the properties and uses of synthetic materials and how they affect society.
Construct arguments that support the law of universal gravitation.
Identify factors that determine the strength of forces created by electric charge and by magnets.
Describe how current flows through series and parallel electric circuits.
Differentiate between electromagnets, generators, and motors.
Identify different forms of energy, and discuss how energy flows through systems.
Explain how the position of an object in a force field relates to its potential energy.
Compute the kinetic energy of moving objects.
Define the law of conservation of energy.
Analyze models that show how heat flows between objects at different temperatures.
Design, build, test, and modify a device that relies on a transfer of thermal energy.
