Electrical and Magnetic Energy

West Haven Public Schools

Unit Planning Organizer

Subject:  Science                  

Grade:  4

Unit:   4.4 – Electrical and Magnetic Energy   

Pacing:  Marking Period 2

Essential Question(s):

1 - If opposites attract, why can you make a magnet move?  Can you move them without having them touch each other?  Or can you move them while objects are in-between them?

 

2 – Ever wonder what happens behind the light switch to make it work?  If you were able to get “behind” the light switch, describe how the energy transfers to turn on the lights.

 

Big Idea(s):

·        Electrical and magnetic energy can be transferred and transformed.

·        Magnets can attract or repel depending on the pole positions.

 

CT State Standards (includes West Haven’s “Priority” GLES’s in BOLD and “Supporting” Standards)

1. Construct complete (closed) and incomplete (open) series circuits in which electrical energy is transformed into heat, light, sound and/or motion energy. B INQ.

 

2.  Draw labeled diagrams of complete and incomplete circuits and explain necessary components and how components must be arranged to make a complete circuit.

 

3. Predict whether diagrammed circuit configurations will light a bulb.  B INQ. 1

 

4. Develop a method for testing conductivity and analyze data to generalize about what type of materials are good electrical conductors and which are good insulators.  B INQ. 3, 4, 5, 6

  

8. Investigate how magnets react with other magnets and analyze findings to identify patterns in the interactions of north and south poles of magnets.  B INQ. 5, 6

 

6. Describe materials that are attracted by magnets.  B INQ. 5

 

7. Design procedures to move objects and separate mixtures of solids using magnets.  B INQ. 3

 

8. Design and conduct fair tests to compare the attractive force of various magnets and identify improvements to the experimental designs.  B INQ. 3

Foss Kits Activities:

 Investigation 1 –

Part 1 – 45 minutes

Part 2 – 45 minutes

Part 3 – 50 minutes

Part 4 – 45 minutes

Investigation 2 –

Part 1 – 40 minutes

Part 2 – 40 minutes

Investigation 4 –

This has been tough to fit in.  It can be done, but if the other Investigations are done thoroughly, this one could be a great review and lead to higher level learning and application of taught lessons.
