CMT Expected Performances
C1. Describe the properties of common elements, such as oxygen, hydrogen, carbon, iron and aluminum.
C2. C2. Describe how the properties of simple compounds, such as water and table salt are different from the properties of the elements of which they are made.
C3. Explain how mixtures can be separated by using the properties of the substances from which they are made, such as particle size, density, solubility and boiling point.
C4. Describe how abitotic factors such as temperature, water and sunlight, affect the ability of plants to create their own food through photosynthesis.
C5. Explain how populations are affected by predator – prey relationships.
C6. Describe common food webs in diff erent Connecticut ecosystems.
C7. Describe the effect of heating on the movement of molecules in solids, liquids and gases.
C8. Explain how local weather conditions are related to the temperature pressure and water of the atmosphere and proximity to a large body of water.
C9. Explain how the uneven heating of the Earth’s surface causes w inds and affects the seasons.
C10. Explain the role of septic and sewage systems on the quality of surface and ground water.
C11. Explain how human activity may impact water resources in Connecticut, such as ponds, rivers and the Long Island ecosystem.
C12. Explain the relationship among force distance and work, and use the relationship (W=F x D) to calculate work done in lifting heavy objects.
C13. Explain how simple machines, such as inclined planes, pulleys and levers are used to create mechanical advantage.
C14. Describe how different types of stored energy (potential) energy can be used to make objects move.
C15. Describe the basic structures of an animal cell, including the nucleus, cytoplasm, mitochondria and cell membrane, and how they function to support life.
C16. C16. Describe the structures of the human digestive, respiratory and circulatory systems and explain how they function to bring oxygen and nutrients to the cells and expel waste materials.
C17. C17. Explain how the human musculoskeletal systems support the body and allows movement.
C18. Describe how folded and faulted rock layers provide evidence of gradual up and down motion of the Earth’s crust.
C19. Explain how glaciation, weathering and erosion create and shape valleys and floodplains.
C20. C20. Explain how the boundaries of tectonic plates can be inferred from the location of earthquakes and volcanoes.
C21. Describe how freezing, dehydration, pickling and irradiation prevent food spoilage caused by microbes.
C22. Calculate the average speed of a moving object and illustrate the motion of objects in graphs of distance over time.
C23. Describe the qualitative relationships among force, mass and changes in motion.
C24. Describe the forces acting on an object moving in a circular path.
C25. Explain the difference in cell division in somatic and germ cells.
C26. Describe the structure and function of the male and female human reproductive systems, including the process and egg and sperm development.
C27. Describe how genetic information is organized in genes on chromosomes, and explain sex determination in humans.
C28. Explain the effect of gravity on the orbital movements of planets in the solar system.
C29. C29. Explain how the relative motion and relative position of the sun, Earth and moon affect the seasons, phases of the moon, and eclipses.
C30. Explain how beam, truss and suspension bridges are designed to withstand the forces that act on them.
