Course Overview

This Physical Science course presents the fundamentals of physics and chemistry. Students explore the amazing universe we live in, including motion, energy, the nature of matter and atoms, how chemicals mix and react, and the forces that hold the universe together.

Among other subjects, students study:

  • Structure of atoms
  • Elements and the Periodic Table
  • Chemical reactions
  • Forces, including gravitational, motion, acceleration, and mass
  • Energy, including light, thermal, electricity, and magnetism

Course Outline

Introduction to Physical Science

What does physical science cover? Everything physical, which covers quite a lot. Begin your journey into physical science by learning about measurements and how to do proper lab procedures. You will also be introduced to lessons that will prepare you for standardized tests in science.

  • Introduction to Physical Science
  • Physical Systems
  • Measurement and the International System
  • Laboratory: Measured Steps
  • Laboratory: Density
  • Working with Model Problems
  • Model Problems

Matter

Have you ever played solitaire, where you arrange cards horizontally and vertically looking for connections? Russian scientist Dmitri Mendeleev did, and he was inspired to create the pattern of the Periodic Table. This pattern displayed in the periodic table helps us understand atoms, chemical reactions, chemical formulas, chemical compounds, atomic mass, and other concepts covered in this unit.

  • Atoms
  • Atomic and Mass Numbers
  • Elements and the Periodic Table
  • Design of the Periodic Table
  • Molecules
  • Properties of Matter
  • States of Matter
  • Physical and Chemical Changes

Chemistry

When you see the word chemistry, you may have an image of someone in a lab wearing goggles pouring liquids from one beaker to another. But chemistry surrounds you every day. Cars are built with chemicals and run on chemical fuel. Chemicals make up the clothes you wear and the food you eat. You breathe chemicals, your computer and radio are composed of chemicals, and our world today is dependent on chemicals.

  • Chemical Bonding
  • Chemical Reactions
  • Chemical Formulas
  • Laboratory: Testing and Producing Gases
  • Rates of Chemical Reactions
  • Chemical Equations
  • Laboratory: Dissolving Metals
  • Mixtures
  • Separating Mixtures
  • Solutions
  • Substances
  • Laboratory: Separating Ingredients
  • Acids and Bases
  • Model Problems

Force and Motion

When you roll a marble across a room, you open the door to understanding the same rules of motion that keep airplanes flying and pendulums swinging. What are these forces? What are the "laws" of motion? Come learn about displacement, speed, acceleration, Newton's laws of motion, and gravitation.

  • Force
  • Gravitational Force
  • Motion
  • Laboratory: Calculating Speed
  • Speed and Velocity
  • Measuring Speed and Velocity
  • Acceleration
  • Newton's First Law of Motion
  • Mass and Weight
  • Newton's Second Law of Motion
  • Newton's Third Law of Motion
  • Buoyant Forces
  • Laboratory: Precious Cargo
  • Model Problems

Energy

Nothing stays the same, at least not in our universe. Energy is constantly changing from one form to another, whether it's the light in your house or the sound of a horn. The good thing is you can use this changing energy to do all sorts of work. Scientists can use mass to create energy, use explosions for transportation, and use electricity to make our work easier. Learn about the different energy that constantly surrounds you, and how you use this energy in your everyday life.

  • Energy
  • Work
  • Kinetic Energy
  • Potential Energy
  • Laboratory: The Pendulum
  • Laboratory: Using a Lever
  • Simple Machines
  • Compound Machines
  • Laboratory: Heat Flow
  • Thermal Energy
  • Temperature
  • Model Problems

Waves, Sound, and Light

At this very moment, you have a lot of waves traveling to your body. You have sound waves you can hear and light waves you can see, but there's even more that you cannot see. There are radio waves, radiation, magnetism, and other invisible waves that you use to cook with, navigate by, and communicate. Explore the different waves you're being exposed to every second of every day.

  • Waves
  • Electromagnetic Waves
  • Light Waves
  • Laboratory: Path of Light
  • Reflection and Refraction
  • Lenses
  • Model Problems

Electricity and Magnetism

You've investigated forces, learned about energy, and examined waves; now look at electricity and magnetism, two particular forms of energy that are quite important to you. Yes, electricity keeps your computer on and your mp3 player going. But do you know why electricity is so useful? Do you wonder how to build your own circuits and currents? Do you know how to build a basic motor?

  • Electric Charge
  • Electric Currents
  • Electric Circuits
  • Laboratory: Series and Electric Circuits
  • Magnetism
  • Electricity and Magnetism
  • Laboratory: Motoring On!
  • Motors and Generators
  • Model Problems

Scientific Investigation

Scientists conduct experiments and form conclusions. Now you can do the same thing. Be a scientist as you design and carry out your own experiment. Discover how the scientific process works, what makes it different from just guessing, and why it's the most powerful and successful way of figuring out how the forces of nature work.

  • Scientific Methods
  • Design and Set-Up Your Experiment
  • Data Collection
  • Data Analysis
  • Reporting Conclusions
  • Create a Display
  • Oral Presentation

Additional Information

Course Length 12 Months
Prerequisites N/A
Course Materials

Many K12 courses utilize physical materials in addition to the online content.  These materials may include the following.


K12
Standard Kits

STANDARD kits contain K12 course materials that are required for completion of the course.  These kits include K12 authored materials and/or difficult to procure materials that a student needs to complete a course. Printed reference guides are not included in Standard kits.


Consumable
Materials

CONSUMABLE kits contain only those materials from the standard kit that are intended for one time use. Families who purchase a Standard kit for Child A could later purchase a Consumable kit for Child B to complete the same course.


Additional
Materials

Offered for added convenience, ADDITIONAL kits contain easily obtained materials needed for the course which a family may already have in their home. 


Learning
Coach and/or Student Reference Guides are available for purchase with some courses.  Electronic versions of these reference guides are also available within digital courses.

  1. A great science foundation for high school
    review by Eileen W. on 8/11/2016

    This course provides a great foundation for chemistry, physics and more advance science study in high school. Students are given a chance to carry out several experiments, see the scientific laws in action. This course will challenge your child to grow in his/her scientific study while at the same time having fun learning. The science project and oral presentation provide an excellent opportunity for your student to prepare a solid scientific study and at the same time practice oral presentation skills.

To use this course, you'll need a computer with an Internet connection.  Some courses require additional free software programs, which you can download from the Internet.
