Fifth Grade Science Unit 1: EARTH AND SPACE Topic: Cycles and Patterns in the Solar System Time Frame: September-October Content Statements Review of Scientific Method (August) The solar system includes the sun and all celestial bodies that orbit the sun. Each planet in the solar system has unique characteristics. The distance from the sun, size, composition and movement of each planet are unique. Planets revolve around the sun in elliptical orbits. Some of the planets have moons and/or debris that orbit them. Comets, asteroids and meteoroids orbit the sun. Student Expectations Recognize that there are eight major planets in the solar system and they all orbit the sun. Compare and contrast these planets. Recognize that other celestial bodies also orbit the sun. These can include dwarf planets, comets, asteroids, meteoroids and comets. Identify a telescope as a tool that can be used to magnify the appearance of objects in the solar system. Instructional Strategies Choose a planet (other than Earth) and research and develop a plan to colonize the planet with humans. Evaluate current conditions and what would be needed to meet the basic requirements for humans to live on Mars. Make a final recommendation based on the research. Present to class. Choose a major planet. Plan and build a scaled model that can demonstrate the planet size and rotation orbit in relationship to the sun and the Earth. Conduct the demonstration and explanation in class. Make a table, chart or graphic that interprets the general characteristics of the major planets in the solar system. Use real data to compare and contrast the findings. Research the history of the exploration of the solar system or a recent space discovery. Make a timeline or write a report to interpret and clarify the major events, the tools and technology used, and the discoveries made. Share findings with class. The sun is one of many stars that exist in the universe The sun appears to be the largest star in the sky because it is the closest star to Earth. Some stars are larger than the sun and some stars are smaller than the sun Differentiate between the sun and red dwarf or blue giant star. Make a table or chart to represent the comparison. Identify the sun as a mediumsized star and the only star in the solar system. Suggestions from the State Research areas on Earth that receive direct sunlight. Critique different zones of the Earth. Evaluate data and make a recommendation to locate a solar energy facility. Share and defend recommendation with the class. Choose a planet (other than Earth) and research and develop a plan to colonize the planet with Most of the cycles and patterns of motion between the Earth and sun are predictable Earth’s revolution around the sun takes approximately 365 day. Rotation -24 hours-this makes sun, stars and moon appear to change position. Earth’s axis is titled at an angle of 23.5 degrees. This tilt affects amount of direct sunlight that Earth receives throughout year. Recall that there are many other stars in the universe and they are different sizes, but the sun appears larger because it is closer to the Earth. Represent the sun, moon and Earth and their orbits graphically and to scale. Use actual data and measurements for the representation. Recognize that the rotation of Earth on its axis produces day and night, which is why the sun, stars and moon appear to change position in the sky. humans. Evaluate current conditions and what would be needed to meet the basic requirements for humans to live on Mars. Make a final recommendation based on the research. Present to class. Suggestions from the State Research areas on Earth that receive direct sunlight. Critique different zones of the Earth. Evaluate data and make a recommendation to locate a solar energy facility. Share and defend recommendation with the class. Using a simple model, investigate the positions of the sun, moon and Earth to detect and test the reasons why the moon and sun appear to change position in the sky and the phases of the moon., Science Inquiry and Applications Science Inquiry and Application During the years of grades 5-8, all students must use the following scientific processes, with appropriate laboratory safety techniques, to construct their knowledge and understanding in all science content areas: Identify questions that can be answered through scientific investigations; Design and conduct a scientific investigation; Use appropriate mathematics, tools and techniques to gather data and information; Analyze and interpret data; Develop descriptions, models, explanations and predictions; Think critically and logically to connect evidence and explanations; Recognize and analyze alternative explanations and predictions; and Communicate scientific procedures and explanations. Unit 2: Life Science Topic: Interconnections within Ecosystems Time Frame: November-February Content Statements Student Expectations Compare the roles of producers, consumers Organisms perform a variety of roles in an and decomposers and explain how they ecosystem Populations of organisms can be categorized by how they acquire energy Food webs can be used to identify the relationships among producers, consumers and decomposers in an ecosystem work together within an ecosystem Given a list of organisms and a description of their interactions within an environment, classify them as producers, consumers, decomposers or by type of symbiotic relationship (was 7 ) (mutualism, commensalism and parasitism)_ th All of the processes that take place within organisms require energy For ecosystems, the major source of energy is sunlight Energy entering ecosystems as sunlight is transferred and transformed by producers into energy that organisms use through the process of photosynthesis. That energy then passes from organism to organism as illustrated in food webs. In most ecosystems, energy derived from the sun is transferred and transformed into energy that organisms use by the process of photosynthesis in plants and other photosynthetic organisms. Science Inquiry and Applications Explain ways that humans can improve the health of ecosystems (e.g., recycling wastes, establishing rain gardens, planting native species) Given a list of common organisms and a description of their environmental interactions, draw a food web using arrows to illustrate the flow of energy. Properly identify the producers and consumers. Instructional Strategies Suggestions from the State: Design and build a self-sustaining ecosystem (e.g., terrarium, bottle biology) Consider size of container, location, light, humidity and organisms that will support one another. Investigate change in an established model of an ecosystem over time. Design experiments to observe what happens when on species is changed.

Unit 3: Physical Science Topic: Light, Sound and Motion Time Frame: March-May Content Statements The amount of change in movement of an object is based on the mass of the object and the amount of force exerted Movement can be measured by speed Earth pulls down on all objects with a gravitational force Any change in speed or direction of an object requires a force and is affected by the mass of an object and the amount of force applied. (was 8 and 9 ) th th Light and sound are forms of energy that behave in predictable ways Light travels and maintains its direction until it interacts with an object or moves from one medium to another and then it can be reflected, refracted or absorbed. Sound is produced by vibrating Student Expectations Instructional Strategies Recognize that increasing the force acting on an Suggestions from State: Plan and implement a scientific experiment that determines how the mass of an object (or amount of force acting on a object) affects how the motion of an object changes. Analyze the data to determine trends. Formulate a conclusion. Represent the data graphically. o Clarify specifically how data will be measured and how it will be used to determine the speed of the car. Design a system by which police officers could make observations from an airplane to determine the speed of a car. Give an example of how the speed could be calculated from the measurements. Compare and rank the relative change in motion for three objects of different masses that experience the same force. object will result in greater changes in motion. Recognize that objects with greater mass will change their motion less than objects with less mass. Predict what will happen to the motion of an object. Provide the speed and direction of motion and a force diagram on the object. Explain the prediction. Recall the mathematical relationship between distance, time and speed. Identify what factors must be measured to determine speed. Identify three ways the motion of object can be changed (e.g., speed up, slow down, change direction) Identify two factors that influence the amount of change in motion of an object. Recognize that the angle that light approaches a reflective surface affects the direction in which the light is reflected. Recognize that refraction involves bending of light when passing into a new medium. Recognize that longer tubes produce lower pitches and shorter tubes Suggestions from State Design a mirror system to use when building a periscope. Draw a picture of the periscope design and trace the path of light as it travels from the object to the eye. Plan and implement a scientific investigation to determine the ideal angle to place a reflective surface to bend light through a right angle. Plan and implement a scientific experiment to investigate what happens when light enters a new medium Pictorially represent the path light takes when traveling objects and requires a medium through which to travel. The rate of vibration is related to the pitch of the sound. produce higher pitches Draw a picture of a pencil halfsubmerged in water. Trace the path of light as it travels from a submerged part of the pencil to the eye. Use this picture to explain why the pencil appears to be bent or broken when placed in water. Recall that increasing the rate of vibration can increase the pitch of a sound from one medium to another Design two different musical instruments, one using blowing and one using plucking that can create the same three notes. Plan and implement a scientific investigation to investigate how the length of PVC tubing affects the pitch of the sound. Summarize the data in a way the is clear and easy to understand.
