2. 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.

3. 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
