Study Notes
Grade 4 Science - Q2 Periodic Test
-
Skeletal System: Composed of all the bones in the body.
-
Muscular System: Important for supporting the body and enabling movement (e.g., lifting).
-
Respiratory System: Involved in gas exchange (oxygen and carbon dioxide). Quick responses to stimuli like touching a hot stove rely on this system.
-
Digestive System: Responsible for breaking down food to be absorbed by the body. A full feeling after a meal is related to this.
-
Circulatory System: Transports oxygen and nutrients to the body. Important in activities like running a marathon where the body needs consistent oxygen and nutrient supply for the muscles.
-
Body's Functions: The muscles facilitate lifting, the skeletal system supports, the respiratory system facilitates gas exchange, and the digestive system breaks down food.
-
Functions of Systems: Bones support and protect. Breathing rapidly to fuel muscles may mean the circulatory system is working hard. A body's reaction to a hot stove is a function of the muscular system.
Digestion leads to a feeling of fullness. -
Plant Systems: Roots absorb water and nutrients, shoots capture sunlight for photosynthesis, enabling plant growth.
-
Trophic Levels: Energy flows through organisms, and a portion is transferred to the next level.
-
Food Chain/Web: Understanding the relationships (herbivores, carnivores, omnivores, producers, decomposers) within ecosystems. Herbivores eat plants, carnivores eat animals, and omnivores eat both plants and animals.
-
Habitat and Adaptation: Plants and animals adapt to their environments (e.g., plants thrive in areas with rich soil and ample sunshine.)
-
Organism Groups: Different organism groups live according to their needs and environments
-
Organ Systems: The body contains organ systems—groups of organs that work together to do a particular job.
-
Metamorphosis: The process of change in the form of living organisms (some insects, frogs, etc.).
-
Organisms:
- Examples of organisms found in different habitats.
- Differentiating between omnivores, carnivores, and herbivores.
-
Question Types: The test covers questions relating to organ systems, plant structure, trophic levels, food chains/webs, habitats, adaptations, and the categorisation of organisms.
