Dash & Dot: Forces of Attraction (Gr. 3-6)


Magnets attract each other by exerting a magnetic force, but what makes an object a magnet? In this lesson, Dash will help students conduct a scientific experiment to find out which objects are more magnetic than others and how magnets interact with each other.


  • Develop hypotheses about the magnetism of different objects
  • Test hypotheses by running an experiment
  • Write a conclusion to support experimental data
  • Learn about the reactions of everyday objects to a magnet and the reaction between two magnets
  • Program Dash to help with the experiments
