Grade 4 Science test

For their test on Monday on the Habitats and Communities Unit, students will need to demonstrate the following:

-an understanding that habitats are areas that provide plants and animals with the necessities of life (food, air, water, space, light)

-an understanding of food chains as systems in which energy  from the sun is transferred to producers (plants) and then to consumers (animals) and give examples of food chains with one producer and 2-3 consumers.

-ability to classify organisms according to their role in the food chain (ie: humans are consumers, wheat is a producer, an earthworm is a decomposer)

-ability to identify animals as carnivores, herbivores, or omnivores (ie: wolves and snakes are carnivores as they only eat other animals; rabbits and horses are herbivores as they only eat plants; humans and pigs we omnivores as they will eat both plants and animals)

-ability to describe structural adaptations that allow plants and animals to survive in a specific habitat (ie: the thick skin of a cactus allows it to store water in a dry desert habitat, a duck's feet are webbed to allow it to move quickly in the water)

-an understanding of why all habitats have limits to the number of plants and animals they can support (why can an animal not continue to increase in number if there are no predators around to kill them? What would happen if the numbers kept increasing?)

Students have been asked to take home all of their notes and worksheets from their folder to begin reviewing for the test.
