Assessment: Why do predator and prey populations change? 17 April 2017 L.O. What I am looking for is for you to be able to draw a cartoon to explain predator and prey cycles. Starter: write a definition for the following words:- Decrease Increase Population Predator Prey You need a pen, ruler and a pencil

Task: Draw a cartoon to explain predator and prey cycles. Level ladder: What is your target level? Use the level ladder to help you reach it: To get level You might have: 5 Chosen the suitable predator and prey. Described some of the adaptations of the predator and prey, giving reasons. Described how the prey population changes when they are eaten by predators. Explained how a change in the prey population effects the predator population. Stated a reason why the populations change. 6 Explained a range of adaptations of the predator and prey. Used detailed scientific knowledge and understanding to explain predator and prey cycles. Explained how seasonal changes may affect the sizes of predator and prey populations. Explained how predator adaptations may help them to survive in times of low prey populations. 7 Considered the short-term and long-term effects of these cycles. Used a quantitative model to explain the changes in population size.

Help given (only 1 lesson to do this in silence!!!! You will need a pencil, pen, rubber and a ruler Key words: Decrease Increase Population Predator Prey dissolve, solute, solution, solvent, sugar, tea
