What Causes The Northern Lights.mp4

Explanation

Practical

Group:

  • 10 x Magnets
  • 10 x Boxes or items to hide magnets in
  • 5 x boxes that look like they could have magnets in
  • 11x Compasses

Boxes are placed all around the room. The students will have 10 minutes to try and guess which boxes have magnets in base don their plotting compasses

Big Question

KS3 - P6.7 - End point task

Practical

Practical :

11 x Cores

11 x sets of wire

11 x sets of wire cutters

11 x sets of 5 x paper clips

11 x sets of power packs

11x crocodile clips

11 x variable resistors

11x ammeters


Students are to investigate current and strength of electromagnet they can pick up. Studnets must be instructed to be very neat and tidy with coils. if not ordered and tight they will barely pick up 1.
