The Science Curriculum in Primary and Lower Secondary Grades

Science education at the primary school level is currently regulated by 14 curricula. In contrast to mathematics, the primary school science curricula are not determined by the national educational standards. In the curriculum for integrated science (Sachunterricht) of North Rhine-Westphalia, educational objectives are described as content-based as well as process-based competency expectations. Exhibit 3 is an example of an overview of one science topic and curriculum focus at the primary school level in North Rhine-Westphalia, a fairly representative curriculum for the 16 states.18

Exhibit 3: Science Curriculum Guidelines for the Primary Level (up to Grade 4) in North Rhine-Westphalia, Topic: Nature and Life

Content Domains Student Competenciese
Nature and Life
Materials and Their Transformation
  • Collect animate and inanimate materials from nature and organize them according to specific criteria
  • Examine characteristics of materials and describe similarities and differences
  • Examine visible material changes of animate and inanimate natural objects, present results, and describe them (i.e., states of matter such as water; dehydration processes of fruits; dissolution abilities of solids materials; and chemical transformations through combustion)
Heat, Light, Fire, Water, Air, and Sound
  • Discover characteristics of heat, light, fire, water, air, and sound through experimentation
  • Observe and describe the importance of water, heat, and light for humans, animals, and plants
  • Plan an experiment and evaluate results
  • Describe changes in nature and demonstrate stages of change (e.g., the water cycle and the seasons)
Magnetism and Electricity
  • Examine and describe the effect of magnets on various materials
  • Construct simple electric circuits, and describe, explain, and follow safety rules when using electricity
Human Body, Senses, Nutrition, and Health
  • Examine and describe the meaning of the five senses in daily life
  • Identify and describe the functions of individual sensory organs
  • Identify and describe different nutrition habits and their effects
  • Describe the structures and basic functions of the human body (blood circulation, respiration, digestion)
  • Describe hygiene basics, healthy nutrition, and healthy lifestyle
  • Formulate rules and advice for living a healthy lifestyle
Animals and Plants, and Their Habitats
  • Identify body structures and living conditions of animals and document the results
  • Observe and identify plants and their typical characteristics, and describe their habitat
  • Describe the development of animals and plants
  • Describe the relationship between habitats and living conditions for animals, humans, and plants

For most tracks at the secondary school level, science is taught in the following separate subjects: biology, chemistry, physics, and geography. Some states offer science as an integrated subject in certain secondary school tracks, covering some or all the subjects (mostly at Hauptschulen or Gesamtschulen).

Eighth grade science education currently is regulated by more than 40 different curricula, which are informed by the national educational standards (except geography). The curricula differ across grades and tracks, with the more demanding tracks covering content more quickly or in more detail. Some content (e.g., thermodynamics) is covered only in the more demanding secondary tracks.

Exhibit 4 presents a representative overview of topics covered in biology, chemistry, physics, and geography from the eighth grade curriculum for the Realschulbildungsgang (extensive general education) in North Rhine-Westphalia.19-22
