Cambridge Assessment International Examination’s goals for its lower levels science courses include:
使学生能够:
- develop a positive attitude towards science that encourages enjoyment, confidence and curiosity
- understand how the respiratory system works, including breathing, gas exchange, blood and respiration
- explore dissolving and solubility, and learn how to separate substances using practical methods
- describe forces, speed, motion and pressure, and use particle ideas to explain how substances behave
- understand different ecosystems, how organisms interact, and how human actions can affect habitats
- recognise the structure of the atom and understand ideas linked to purity, weather, climate and atmospheric change
- investigate how light behaves through reflection, refraction and colour, and describe what we see in space
- understand nutrients, healthy diets, growth and how the body moves
- describe common chemical reactions, including exothermic and endothermic changes and reactions of metals
- explore magnetism, magnetic fields and electromagnets, and investigate how magnets can be used
- develop practical skills by planning enquiries, collecting and analysing data, and drawing evidence-based conclusions
- communicate scientific ideas clearly and use models to explain their thinking
- appreciate how scientific knowledge develops through investigation, collaboration and peer review
- recognise how science is used in society and industry and evaluate its impact on people and the environment
- build a strong foundation for further study in science
