Type: Interactive/Game

Overview:

Meet a clingy red-eyed tree frog with a magnetic personality as you learn about magnets, magnetic forces, and how magnets make things move. Use main ideas and key phrases to help you read. Then, invent your own amazing magnet technology for the future.

Content Standard(s):
 English Language Arts ELA2015 (2015) Grade: 3 11 ) Determine the main idea of a text; recount the key details and explain how they support the main idea. [RI.3.2] Alabama Alternate Achievement Standards AAS Standard: ELA.AAS.3.11- Identify the main idea of an informational text; identify details in an informational text that support the main idea. Science SC2015 (2015) Grade: 3 3 ) Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets). NAEP Framework NAEP Statement:: P4.5: Magnets can repel or attract other magnets. They can also attract certain nonmagnetic objects at a distance. Unpacked Content Scientific And Engineering Practices:Asking Questions and Defining ProblemsCrosscutting Concepts: Cause and EffectDisciplinary Core Idea: Motion and Stability: Forces and InteractionsEvidence Of Student Attainment:Students: Observe and manipulate objects to identify cause and effect relationships of electrical interactions between two objects not in contact with one another. Observe and manipulate objects to identify cause and effect relationships of magnetic interactions between two objects not in contact with one another.Teacher Vocabulary:Explore Manipulate Cause and Effect Electrical Interactions Magnetic Interactions Magnet Repel AttractKnowledge:Students know: The size of the force can affect the electrical and magnetic interaction of two objects not in contact with one another. The orientation of magnets can affect the magnetic interaction of two objects not in contact with one another. The repulsion or attraction of magnets can affect the magnetic interaction of two objects not in contact with one another. The presence of a magnet and the force the magnet exerts on other objects affects the magnetic force of two objects not in contact with one another. The electrical charge of an object can affect the electrical force of two objects not in contact with one another.Skills:Students are able to: Explore electrical interactions between two objects not in contact with one another. Explore magnetic interactions between two objects not in contact with one another. Determine cause-and-effect relationships of electrical interactions between two objects not in contact with one another. Determine cause-and-effect relationships of magnetic interactions not in contact with one another.Understanding:Students understand that: Cause and effect relationships are routinely identified, tested, and used to explain change. Magnetic and electrical forces affect the way objects interact.AMSTI Resources:AMSTI Module: Forces and Investigations Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.3.3- Recognize cause-and-effect relationships of magnetic interactions between two objects (opposite poles attract, similar poles repel). Science SC2015 (2015) Grade: 3 4 ) Apply scientific ideas about magnets to solve a problem through an engineering design project (e.g., constructing a latch to keep a door shut, creating a device to keep two moving objects from touching each other such as a maglev system).* NAEP Framework NAEP Statement:: P4.5: Magnets can repel or attract other magnets. They can also attract certain nonmagnetic objects at a distance. Unpacked Content Scientific And Engineering Practices:Constructing Explanations and Designing SolutionsDisciplinary Core Idea: Motion and Stability: Forces and InteractionsEvidence Of Student Attainment:Students: Identify and describe a simple design problem that can be solved by applying a scientific understanding of the forces between interacting magnets. Identify and describe the scientific ideas necessary for solving the problem. Identify and describe the criteria for a successful solution to the problem. Identify and describe the constraints (limits) for solving the problem.Teacher Vocabulary:Magnet Properties Engineering Design Process (Ask, Imagine, Plan, Create, Improve) Attract Repel ForcesKnowledge:Students know: Magnetic forces between a pair of objects do not require that the objects be in contact with each other. The sizes of the forces in a magnetic situation depend on the properties of the objects, the distances apart, and their orientation relative to each other.Skills:Students are able to: Define a problem that can be solved with magnets. Apply scientific ideas about magnets. Solve a problem with scientific ideas about magnets through an engineering design project.Understanding:Students understand that: Scientific discoveries about the natural world, such as magnets, can often lead to new and improved technologies, which are developed through the engineering design process.AMSTI Resources:AMSTI Module: Forces and Investigations Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.3.4- Apply scientific ideas about magnets to solve a problem. (e.g., using a magnet to pick up an object, using a magnet to push or pull an object)
