1 CONNECTICUT SCIENCE FRAMEWORK Grade 6 Core Themes, Content Standards and Expected Performances Properties of Matter How does the structure of matter affect the properties and uses of materials? Materials can be classified as pure substances or mixtures, depending on their chemical and physical properties. Mixtures are made of combinations of elements and/or compounds, and they can be separated by using a variety of physical means. Pure substances can be either elements or compounds, and they cannot be broken down by physical means. Scott Foresman Grade 6

5 Matter and Energy in Ecosystems How do matter and energy flow through ecosystems? An ecosystem is composed of all the populations that are living in a certain space and the physical factors with which they interact. Populations in ecosystems are affected by biotic factors, such as other populations, and abiotic factors, such as soil and water supply. Populations in ecosystems can be categorized as producers, consumers and decomposers of organic matter. C 4. Describe how abiotic factors, such as temperature, water and sunlight, affect the ability of plants to create their own food through photosynthesis. Grade 6, Unit A, Life Science, Chapter 6, Biomes. In this chapter students discover: - how the biosphere is organized - what Earth s biomes are - how Earth s biomes differ Lesson 1: How are organisms on Earth connected? Connections in the Biosphere Organization of the biosphere Meeting the Needs of Organisms Adaptations Grade 6, Unit A, Life Science, Chapter 5, Plants. In this chapter students discover: - what the parts of a vascular plant are - how photosynthesis and respiration are related - how plants grow Lesson 2: How do plants get and use energy? Photosynthesis Energy from Food Carbon Dioxide Oxygen Cycle Scott Foresman Grade 6

6 C 5. Explain how populations are affected by predator-prey relationships. Grade 6, Unit A, Life Science, Chapter 7, Ecosystems. In this chapter students discover: - how adaptations help organisms survive in ecosystems - how energy and materials travel through ecosystems - the ways ecosystems change Lesson 3: How do organisms compete for resources? Competition Predators and Prey Symbiosis C 6. Describe common food webs in different Connecticut ecosystems. Grade 6, Unit A, Life Science, Chapter 7, Ecosystems. In this chapter students discover: - how adaptations help organisms survive in ecosystems - how energy and materials travel through ecosystems - the ways ecosystems change Lesson 2: How do organisms get energy? Energy Flow in Ecosystems Food Chains Food Webs Energy Pyramid Scott Foresman Grade 6

7 Energy in the Earth s Systems How do external and internal sources of energy affect the Earth s systems? Variations in the amount of the sun s energy hitting the Earth s surface affect daily and seasonal weather patterns. Local and regional weather are affected by the amount of solar energy these areas receive and by their proximity to a large body of water. C 7. Describe the effect of heating on the movement of molecules in solids, liquids and gases. Grade 6, Unit C, Physical Science, Chapter 13, Matter. In this chapter students discover: - that a substance has a unique set of chemical and physical properties - how to calculate density and use it to identify a substance - how matter can change chemically and physically Lesson 2: How can matter change?

Thermal Energy Heat Conduction Convection Radiation Insulation Using Insulators Scott Foresman Grade 6

8 C 8. Explain how local weather conditions are related to the temperature, pressure and water content of the atmosphere and the proximity to a large body of water. Grade 6, Unit B, Earth Science, Chapter 12, Climate and Weather.
