Properties of Matter - How does the structure of matter affect the properties and uses of materials? 6.1 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 using a variety of physical means. ¨ Pure substances can be either elements or compounds, and they cannot be broken down by physical means.	CA1. Describe the properties of an atom. C 1. Describe the properties of common elements such as oxygen, hydrogen, carbon, iron and aluminum. C 2. 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. C 3. 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.
Matter and Energy in Ecosystems – How do matter and energy flow through ecosystems? 6.2 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 plants’ ability to create their own food through photosynthesis. C 5. Explain how populations are affected by predator-prey relationships. C 6. Describe common food webs in different Connecticut ecosystems.
Energy Transfer and Transformations – What is the role of energy in our world? 7.1 Energy provides the ability to do work and it can exist in many forms. ¨ Work is the process of making objects move through the application of force. ¨ Energy can be stored in many forms and can be transformed into the energy of motion.	C 12. Explain the relationship between force, distance and work, and use the relationship (W=F x D) to calculate work done in lifting heavy objects. C 13. Explain how simple machines such as inclined planes, pulleys and levers are used to create mechanical advantage. C 14. Describe how different types of stored (potential) energy can be used to make objects move.

Forces and Motion – What makes objects move the way they do? 8.1 An object’s inertia causes it to continue moving the way it is moving unless it is acted upon by a force to change its motion. ¨ The motion of an object can be described by its position, direction of motion and its speed. ¨ An unbalanced force acting on an object changes its speed or direction of motion, or both. ¨ Objects moving in circles must experience force acting toward the center.

C 22. Calculate average speed of a moving object and illustrate the motion of objects in graphs of distance over time. C 24. Describe the qualitative relationships among force, mass and changes in motion.

Science and Technology in Society – How do science and technology affect the quality of our lives? 8.4 In the design of structures there is a need to consider factors such as function, materials, safety, cost and appearance. Bridges can be designed in different ways to withstand certain loads and potentially destructive forces.

C 30. Explain how beam, truss and suspension bridges are designed to withstand the forces that act on them.
