Fifth grade science includes three units covering earth and space science (Earth and Sun), physical science (Mixtures and Solutions), and life science (Living Systems). Earth and Sun is an exploration of the geosphere, the hydrosphere, the atmosphere, and space. Students gain an understanding of earth's rotation by studying shadows and moon's revolution around the earth by creating models and studying moon's phase changes over several weeks. Students use observation and apply their knowledge of earth's rotation and revolution in order to explain why stars appear to change in the night sky. Students compare and contrast the size and distance of Earth, moon, and sun, and the various differences among objects in space. Students study the sun's energy transfer through observations and designing investigations. Earth's atmosphere is explored through a study of the water cycle, weather patterns, climate change, and global warming. Mixtures and Solutions begins with an exploration of creating and separating mixtures. Students use modeling to demonstrate their understanding of dissolving, melting, and saturation. By designing experiments, students compare the relative saturation of mystery solutions. Students observe chemical reactions and the effects of mixing substances with water and prove that new substances are created. Living Systems begins with students exploring and creating food chains and food webs. Students explore and compare animal digestive systems with plant photosynthesis, and students set up experiments with wheat seed plants to further explore plant photosynthesis. Wheat seeds are also used to demonstrate plant vascular systems and students compare and contrast this with human circulatory and respiratory systems. Human nervous system is explored through stimulus and response experimentation. Animal instincts, learned behavior, and plant and animal adaptations are examined and simulated to help explain how organisms survive.
Students and Parents: It is important to work closely with your local school counselor or
registrar to follow the school's enrollment procedures. By clicking the "Start Registration
Request" button below, you will be able to notify the school of your interest in registering for
the online course. However, it is the responsibility of the district or school to review the
registration request and approve or deny the request. Please make a note to follow up with
your school after submitting a registration request.
Unit 2: Mixtures and Solutions (Continue from Semester 1)
I can separate the materials in a mixture.
I can understand the difference between a mixture and a solution.
I can describe the process of dissolving.
I can develop a model to describe something that I cannot observe directly.
I can describe the difference between dissolving and melting?
I can observe solutions to compare their concentration levels.
I can determine the relative concentrations of different solutions.
I can compare the density of solutions.
I can describe how a solution becomes saturated.
I can compare the saturation levels of various substances.
I can use evidence to prove the identity of the substances dissolved in water.
I can observe the effect of mixing two substances together.
I can determine if a chemical reaction has occurred when mixing substances.
Unit 3: Living Systems
Food provides animals with the materials they need for body repair and growth and the energy they need to maintain body warmth and for motion.
Plants acquire their material for growth chiefly from air and water.
Earth’s major systems are the geosphere (solid and molten rock, soil, and sediments),the hydrosphere (water and ice), the atmosphere (air), and the biosphere (living things, including humans). These systems interact in multiple ways to affect Earth’s surface materials and processes. The ocean supports a variety of ecosystems and organisms, shapes landforms, and influences climate. Winds and clouds in the atmosphere interact with the landforms to determine patterns of weather.
Human activities in agriculture, industry, and everyday life have had major effects on the land, vegetation, streams, ocean, air,and even outer space. But individuals and communities are doing things to help protect Earth’s resources and environments
Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gasses, and water, from the environment,and release waste matter (gas, liquid, or solid) back into the environment.
The energy released [from] food was once energy from the sun that was captured by plants in the chemical process that forms plant matter (from air and water).
