Enroll in Science 7 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 7A discusses the major life
processes of organisms, including nutrition, growth and development, and reproduction.
In the first unit, you’ll explore the cell as the structural and functional unit of life. The
second unit covers the growth, development, and modes of reproduction in different
plants and animals. In the third unit, you’ll learn about sensory receptors,
photosynthesis, and cycles of energy transfer that occur in nature.
By the end of this course, you will be able to do the following:
Use the steps of the scientific method to plan a life science investigation.
Use evidence to explain that living things are made up of cells, and create a model
that shows cellular organelles.
Conduct an investigation of cells, and use evidence to argue that the human body is
made up of tissues, organs, and systems.
Research a vaccine, and present a sound argument about its value to public health.
Develop models to describe the similarities and differences between the two types of reproduction.
Perform an experiment, and use the results to predict whether a cabbage plant will
be genetically identical or different from its parents.
Develop an argument that explains how animal behaviors and special plant
structures affect an organism’s chances for reproduction.
Create a Venn diagram to compare the characteristics of different types of organisms.
Gather and use information to explain that sensory receptors respond to stimuli by
sending messages to the brain.
Monitor your food intake, and draw conclusions about your diet compared with the
recommendations for people your age.
Explain the role of photosynthesis in the cycling of matter and flow of energy.
Develop a model that shows how organisms use food to create energy for growth and development.
Plan an investigation that answers a scientific question about the growth needs of yeast.
Use life cycle models to compare and contrast the growth and development of different organisms.
To participate in this course, you should be able to do the following:
Complete basic operations with word processing software, such as Microsoft Word or Google Docs.
Complete basic operations with presentation software, such as Microsoft PowerPoint
or Google Docs presentation.
Perform online research using various search engines and library databases.
Communicate through email and participate in discussion boards.

Course Pacing Guide
This course description and pacing guide is intended to help you stay on schedule with
your work. Note that your course instructor may modify the schedule to meet the
specific needs of your class.
Unit 1: Cells
In this unit, you’ll explore the basic unit of life—the cell. At the beginning of the unit,
you’ll use the scientific method and learn about the theories and scientific tools that are
relevant to life science. You’ll then learn about cells and their internal structures. You’ll
observe plant and animal cells, and create a model of their parts. You’ll also learn about
how cells make up tissues, organs, and important systems of the body.
Unit 2: The Life Cycle
The focus of this unit is reproductive structures and strategies in different organisms. At
the start of the unit, you’ll study life cycles of animals and plants. Next, you’ll learn about
the two kinds of reproduction and explore their similarities and differences. You’ll also
investigate the strategies and behaviors adopted by animals to reproduce. The two
course activities in this unit will give you an opportunity to explore the reproductive
capabilities and structures of plants.
Unit 3: Nutrition and Energy
This unit provides an understanding of how organisms use food to grow and develop.
First, you’ll study how your body’s sensory receptors send messages to your brain—a
key regulator in your body’s food intake. Next, you’ll compare your daily diet with a
recommended diet by comparing calories. You’ll then learn about the process of
photosynthesis in plants. In a hands-on activity, you’ll inspect the process of yeast
fermentation and its benefits to humans. Finally, you’ll develop a model to explain the
process of digestion in various organisms.
Appendix A: Safety Notes and Disclaimer
Each Course Activity and Unit Activity that includes a lab/experiment component will
highlight key safety guidelines using the safety icon (), which appears directly in the
activity. In addition to adhering to those guidelines, you must ensure that you follow
these general safety practices:
Work slowly and safely at all times, and abide by the safety notes and icons.
Pay attention and be alert at all times. Limit any distractions.
Keep your hands away from your nose, eyes, mouth, and skin. Wash your hands
before and after experiments.
If you don’t understand something, ask a teacher or an adult before proceeding.
Wear the required protective gear.
Adult supervision is required for all activities involving an experiment/lab component.
Do not perform experiments that have not been approved. Follow the procedure.
Follow good housekeeping practices. Keep your work area clean.
Abide by all disposal instructions and icons to protect yourself and our planet.
Report any problems or complications to an adult.
