4 Grade 7 Science Curriculum Grade 7 science will be focused on four major unifying themes and skills of science and technology: Models Change and Constancy Systems Scientific Inquiry These are overarching themes and skills that should be included throughout each of the curriculum units. Grade 7 science curriculum includes 3 major units of study: 1. Photosynthesis and Respiration 2. Causes and Effects of Disease 3. Ecosystems and Biomes Causes & Effects of Diseases This unit will introduce the following enduring understandings: 1. Some diseases are transmitted by water, air, and/or physical contact 2. Viruses are non-living particles that are capable of causing disease. 3. Bacteria are living cells that are capable of causing disease. 4. Viral structure allows the parasite to attach to a host to reproduce. 5. Elementary hygiene, (i.e. hand washing, the use of tissue) can greatly reduce the possibility of transmission.. 6. Developments in science and technology are often driven by societal needs. Essential Question: 1. How do microbes impact our lives? 2. How are diseases transmitted? 3. What steps should be taken personally and as a society to prevent the spread of disease? 4. What are some factors that influence the development and use of science and technology. 2
5 PEI connections: Science and Technology - Grades 6 8 C3 Science, Technology and Society - Students identify and describe the role of science and technology in addressing personal and societal challenges. a) Describe how science and technology can help address societal challenges including population, natural hazards, sustainability, personal health and safety, and environmental quality. b) Identify personal choices that can either positively or negatively impact society including population, ecosystem sustainability, personal health, and environmental quality. c) Identify factors that influence the development and use of science and technology. E2 Ecosystems - Students examine how the characteristics of the physical, nonliving (abiotic) environment, the types and behaviors of living (biotic) organisms, and the flow of matter and energy affect organisms and the ecosystem of which they are part. b) Describe ways in which two types of organisms may interact (including competition, predator/prey, producer/consumer/ decomposer, parasitism, and mutualism) and describe the positive and negative consequences of such interactions. 3
