Cycles in our World
There are many different cycles in our world apart from life cycles. These other natural cycles help life continue for all living things and include the rock cycle, the water cycle, the carbon cycle, the cycle of day and night, and the cycle of the seasons.
A good introductory explanation of the importance of cycles in nature, only text though as image link is broken
Animation showing water cycle, carbon cycle and how they relate to global warming. Includes a quiz for each of these areas
Diagrams at students level explaining the 4 cycles of nature - carbon, nitrogen, oxygen and water
Simple water cycle diagram to draw into books, label, colour and explain. The whole activity for this
An interesting explanation of the carbon cycle from School Market Place
Carbon nitrogen oxygen cycles as well as water cycle explained in context of tree growth, more technical
Life cycle of plants
Video below shows how bushfires assist plant growth, in this case gum trees
Interactive life cycle of plants allows you to see plant growth with differing amounts of water and observing different methods of seed dispersal
Watch this video of the rock cycle:
Draw a diagram to explain the rock cycle. Make sure you include the names of the types of rocks: sedimentary, igneous and metamorphic.
Also include process words that tell how one type of rock forms into another type of rock: lava, cools, hardens, magma, wears, heat, pressure, melts.

Examine this interactive diagram of the rock cycle. Watch the linked animations of the processes that produce the different rocks.
Rock cycle experiment with crayons. Great rubric included for following the scientific method
Cycles of the Moon (also called Phases of the Moon)
Take the challenge and place the phases of the moon in their correct location on the calendar
