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
