Third Grade Science


    Forces and Interactions

    • Create a model to demonstrate an understanding of the different strengths and directions of forces needed to balance an object.

    • Plan and conduct an investigation to demonstrate how friction can affect the motion of an object.

    • Investigate the motion of a pendulum and make predictions of its future motion.

    • Discover the cause and effect relationship responsible for magnetic attraction and repulsion. 

    • Design a magnetic device to solve a real-world problem.

    Interdependent Relationships in Ecosystems

    • Demonstrate an understanding that fossils may have formed a very long time ago.

    • Analyze and interpret data about animals, plants, and habitats to develop a model that shows whether a species is suited for one or more habitats.

    • Use data to support a claim that being a part of a group helps some animals obtain food, water, shelter, and protection from predators.

    • Use evidence from a model of an ecosystem to argue that a change in a habitat will affect the organisms living there in specific ways.      

    • Balancing the constraints of time, cost, and materials, evaluate the merit of a solution to a problem caused by an environmental change that may affect the organisms in a habitat.   

    Weather and Climate

    • Gather and interpret weather and climate data over periods of time to predict future patterns.

    • Plan and conduct an investigation to discover the relationship between the water cycle and the weather.

    • Represent data in a bar graph and predict patterns in weather.

    • Evaluate the effectiveness of design solutions for various weather hazards and support claims with evidence.

    • Analyze and interpret climate/weather patterns of four vacation destinations to support an argument for which city is most desirable to visit.

    Inheritance and Variation of Traits

    • Develop a model to demonstrate an understanding that plants and animals have traits inherited from parents.

    • Identify and explain how variation in traits of the same species can be beneficial for survival.  

    • Use data to identify environmental factors that can change some traits of organisms and determine if the new trait gives the species a survival advantage.

    • Develop models demonstrating the unique and diverse life cycles of plants and animals.

    Engineering is Elementary - The Attraction is Obvious:  Designing a Maglev System

    • Identify that everyday objects designed by people as solutions to problems are examples of technology

    • Investigate properties of magnets

    • Use the Engineering Design Process to design, test, and improve their own tabletop maglev transportation systems

    • Troubleshoot and learn from failure

    • Understand the central role of materials and their properties in engineering solutions
