5th Grade Science Curriculum Foss Kit: Mixtures and Solutions Chemistry is the study of the structure of matter and the changes or transformations that take place in it. Learning about the makeup of substances gives us knowledge about how things go together and how they can be taken apart. Learning about changes in substances is important for several reasons: changes can be controlled to produce new materials; changes can be used to give off energy to run machines. The Mixtures and Solutions Module has four investigations that introduce students to these fundamental ideas in chemistry. FOSS EXPECTS STUDENTS TO Gain experience with the concepts of mixture and solution. Gain experience with the concepts of concentration and saturation. Gain experience with the concept of chemical reaction. Apply an operational definition to determine the relative concentrations of solutions. Use group problem-solving techniques to plan investigations. Use measurement in the context of scientific investigations. Apply mathematics in the context of science. Acquire vocabulary associated with chemistry and the periodic table. Be introduced to the concept that all matter is made of very small particles called atoms and that atoms combine to form molecules. Use scientific thinking processes to conduct investigations and build explanations: observing, communicating, comparing, organizing, and relating. Foss Kit: Diversity of Life The FOSS Diversity of Life Course emphasizes the use of knowledge and evidence to construct explanations for the structures and functions of living organisms. Students observe and maintain protests, plants, and animals in the classroom and study their characteristic features. The study progresses from macroscopic to microscopic observation to discover the fundamental unit of life, the cell. Students then investigate organism subsystems and behaviors and consider their diversity of adaptive structures and strategies. FOSS Expects Students To Consider characteristics that are common to all living organisms and develop an operational definition of life. Become familiar with the microscope as a tool used by scientists to study organisms in detail. Discover cells and begin to understand their importance as the basic units of life. Appreciate the diversity of cells that contribute to the diversity of life on Earth. Observe and describe the first developmental stages of a plant and recognize that seeds are living organisms in a dormant state. Conduct investigations to understand how the vascular system transports water throughout a plant and how stomates on leaves regulate the rate of water flow through a plant. Investigate the reproductive systems in flowers to understand the origin of seeds and explore plant adaptations for seed dispersal. Observe and analyze snail structures and behaviors in order to set up a secure and supportive habitat for them. Explore the concept of adaptation by studying the structures and behaviors of an insect, relating those adaptations to the roaches’ natural history and habitat. Explore the Monera (bacteria), Protista (algae), and Fungi kingdoms to understand their roles in the scheme of life. Become familiar with and acquire vocabulary concerning these concepts: cell, tissue, organism, structure, function, behavior, adaptation, system interaction, transpiration, development. Exercise language, social studies, and math skills in the context of science. Use scientific thinking processes to conduct investigations and build explanations: observing, communicating, comparing, organizing, relating, and inferring.
