Learning Objectives Students understand that plants compete with each other for water, nutrients and space. HSW – are able to suggest the factors for which organisms are competing in a given habitat and the reasons for their distribution HSW - know that bar graphs can be used for discrete variables.

Learning Outcomes All students understand that plants need light for photosynthesis. Most students can explain why plants need minerals and suggest the factors for which plants compete in a given habitat. Some students can suggest why some plants are better competitors in a given habitat and evaluate the strategies used by plants to make them successful competitors

BRIGHT COLOURED FLOWERS ATTRACT INSECTS

FAST GROWING WITH LONG TAP ROOTS ROOTS PRODUCE CHEMICALS WHICH POISON COMPETITORS LEAVES LOW TO THE GROUND SHADE OUT COMPETITORS

SEEDS HAVE PARACHUTES WHICH CATCH THE WIND. WIND TAKES SEEDS FAR AWAY FROM PARENT PLANT – REDUCING COMPETITION.
