make an electromagnet. Encircle the oblects
START
Questions:
1. Explain why Elly and Maggie should use those matenals for the
electromagnet
2. How will they test the strength of their electromagnet?
With the materials they gathered, how will Elly and Maggie increase
the strength of their electromagnet?
3. How will they remove the things which will stick to the
electromagnet?
4. Will they get the same result if they will use the other materials in the
maze? (rope, wooden stick, pebbles). Why?

Answer:
1. They need them since:
- Dry cell or battery to power the electromagnet, battery holder as well to hold batteries
- Wire which will be the electromagnet dynamo
- Alligator clips to hold the wire
- Nail which where the wire will be wrapped around
- Paper clips to test
2. They can test it by putting paper clips and determine the strength by how many paper clips can attach end on end of the electromagnet.
3. They can just remove them simply by hand, or if the items are too small and hard to remove, just turn off the electromagnet by removing the power source, AKA the batteries or dry cells.
4. No, since those things are insulators, or poor conductors of electricity.
Hope it helps ^_^
