Potential vs. Kinetic Energy

Kinetic energy is the energy of motion. Potential energy is stored in an object based on its position. Energy can change between potential and kinetic based on an object's motion.

Plant & Animal Cells

Cells are the basic unit of all living things. Plant and animal cells have parts called organelles that help them function and stay organized. We will cover the nucleus, cell wall, cell membrane, mitochondria, chloroplast, lysosomes and vacuoles.

Electricity & Circuits

Electricity is the flow of electrical energy from one place to another. Electricity flows through conductors, but it cannot flow through insulators. A closed circuit is needed for electricity to flow and power our electronics.

Watch Lesson

Simple Machines

Simple machines make work easier. They have few or no moving parts. They change the direction of a force or the amount of force needed to do something.

Watch Lesson

Multicellular Organisms

Multicellular organisms are made of multiple cells working together. Groups of cells form tissues that are specialized for certain functions. Body systems work together to help us survive.

Water Cycle (6-8 Version)

Water on Earth is millions of years old and is constantly being recycling. Water cycles through the processes of evaporation, condensation and precipitation. The water cycle is driven by gravity and energy from the sun.

Air Masses & Weather Fronts

An air mass is a large body of air with roughly the same temperature and humidity. Air masses take on the characteristics of the regions they form in. The interaction of air masses can cause major changes in weather.

Watch Lesson

Reproduction of Living Things

Reproduction transfers genetic information from parents to their offspring. Some organisms reproduce sexually and others reproduce asexually. Animals engage in special behaviors to increase their odds of reproduction.

Watch Lesson

Climate Zones & Ocean Currents

Climates are the result of the unequal heating and cooling of the Earth. Circulation of the atmosphere moves a lot of thermal energy around the globe. Circulation of water in the ocean (ocean currents) can also influence regional climates.

Human Impacts on the Environment

Human population has increased dramatically over the past 2 centuries. An increasing population can strain our natural resources. Humans can make decisions or use technology to reduce our impact on Earth.
