• Fourth-Grade Science Learning Objectives
    Science education should encourage an attitude of inquiry in the world around us, excite an interest in the nature and process of science and explore the relationship of science to society, technology, mathematics and other disciplines. Through the science curriculum, students gain a foundation of process skills, leading to organized reasoning, analytical thinking and problem solving abilities.
    Fourth-grade students in Clayton will complete the following FOSS (Full Option Science System) units:
    Students will learn how human and natural activities can cause land, air, and water pollution. They learn what can be done to reduce pollution and conserve natural resources. They will also learn about the differences between renewable and nonrenewable resources. Noise and light pollution are also introduced. In this module, students will:
    • discover facts about land, air, water, sound, and light pollution.
    • learn how pollution affects various ecosystems.
    • explore ways to prevent and reduce different types of pollution.
    • find out about renewable and nonrenewable energy sources.

    Energy and Electromagnetism

    The Energy and Electromagnetism Module consists of five sequential investigations. Each one designed to introduce or reinforce concepts in physical science dealing with energy and change. Students experience electricity and magnetism as related effects and learn useful applications of electromagnetism in everyday life. In this module, students will:
    • ask questions that can be answered about electricity and magnetism.
    • plan and conduct investigations about electromagnetism; record and organize data using appropriate tools for the task.
    • analyze observations; build reasonable explanations; discuss and justify the merits of explanations.
    • conduct an experiment to determine how the force of attraction between two magnets changes with the distance between the magnets.
    • conduct an experiment to determine how the number of winds in an electromagnet coil affects the strength of the magnetism.
    • design and build a model telegraph system.
    • use tools and techniques to make observations and build explanations about light.

    Weather on Earth
    The constant renewal of water on Earth’s land surfaces by the activities in the atmosphere is one of the defining characteristics of Earth, the water planet. The Weather on Earth Module provides students with experiences to explore the properties of the atmosphere, energy transfer from the Sun to Earth, and the dynamics of weather and water cycling in Earth’s atmosphere. In this module, students will:
    • investigate properties of air.
    • describe the atmosphere using visual displays.
    • use weather instruments to measure temperature, atmospheric pressure, humidity, wind direction, and wind speed.
    • conduct experiments with heating of earth materials and with solar water heaters to build explanations.
    • investigate the conditions that cause condensation and evaporation as part of the water cycle.
    • interpret the data displayed on weather maps and look for patterns over time.
