Enroll in Science 8 with Dolphin STEM Academy
Science is the study of the natural world. It relies on investigations and evidence to
describe the natural events that occur around us. Science 8B is an integrated science
course that covers topics selected from Earth and space science, physical science, and
life science. This course discusses climate change and methods for confronting it, the
physical features of waves and wave technology, and the positive and negative ways
that humans and technology affect the Earth and its ecosystems. In the first unit, you’ll
study the factors that have led to climate change and explore scientific solutions to
address these changes. In the second unit, you’ll learn how waves and interactions
between them can be used to develop new technologies. In the third unit, you’ll broaden
your knowledge of technology-based and human-based threats to the environment and
find ways to reduce their negative impact.
By the end of this course, you will be able to do the following:
Model the greenhouse effect using temperature as a dependent variable.
Explain how current trends in carbon dioxide levels affect Earth’s climate.
Determine the effectiveness of different methods of addressing climate change.
Classify waves based on their characteristics, and use mathematics to model them.
Interpret models of interactions of light and matter.
Assess how light from objects in space provides information about their temperature,
composition, and distance.
Compare and contrast the use of digital and analog signals in communication.
Build a seismograph model, and engineer a model building that can withstand an earthquake.
Analyze data to explain how technology can limit the risk of damage from natural hazards.
Explain how the growing number of humans and their use of natural resources affect Earth’s systems.
Design methods to reduce the negative impact that humans have on the environment.
Understand how changes to the physical or biological components of an ecosystem
affect populations of organisms, and research one effect that humans have on the
Evaluate solutions to maintain biodiversity in an ecosystem, and design a solution to
an environmental problem in an ecosystem.
