Patterns and processes of evolution. How evolution and natural selection are reflected in the similarities and differences of organisms. 

Part 1: Equivalent fractions and the simplest form of a fraction
Part 2: Examples of equivalent fractions
Part 3: Common mistakes and misconceptions

Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.

Part 1: Proper, improper and mixed fractions
Part 2: Examples of proper, improper and mixed fractions
Part 3: Common mistakes and misconceptions

This video explains the theorem of Pythagoras.

Use two methods to find the sum of mixed numbers: improper fractions and mixed numbers

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

• Identify different types of triangles.
• Investigate the relationship between the sides of a right-angled triangle to develop the Theorem of Pythagoras.
• Use the Theorem of Pythagoras to find missing lengths in right angled triangles.

We can analyse the arrows in a food web to identify producers, primary consumers, secondary consumers, and decomposers.
