This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work. 

Plant cells have a cell wall in addition to a cell membrane, whereas animal cells have only a cell membrane. Plants use cell walls to provide structure to the plant. Plant cells contain organelles called chloroplasts, while animal cells do not. Chloroplasts allow plants to make the food they need to live using photosynthesis.

The amount of effort saved when using machines is called mechanical advantage (MA). Simple machines use mechanical advantage as a key property to their functionality, helping humans perform tasks that would require more force than a person could produce. We will use the lever as an example of a simple machine to illustrate the concept of mechanical advantage.

An interactive lesson discussing congruent triangles.

Outcomes

In this course you will learn about:

1. Conditions for congruency.
2. Proving congruent triangles.

In this lesson you will learn that:

• Circuit diagrams are used to show how electrical components are connected in a circuit.
• Individual circuit components are represented using circuit symbols.
• Current is the flow of electrons around a circuit.
• Ammeters are used to measure the current flowing through components. 
• Components in a circuit resist current flow.
• Voltmeters are used to measure the potential difference across components.

By the end of this unit you will be able to:

• Understand when to use Venn diagrams.
• Draw Venn diagrams.
• Interpret Venn diagrams.

The Earth behaves like a giant bar magnet and as such there is a magnetic field present around it. The Earth’s magnetic field is thought to be caused by flowing liquid metals in the outer core of the planet which causes electric currents and a magnetic field.
