fill in the blank question\n\nyou can use a sieve to separate sesame seeds from sunflower seeds because their differ. you can use a to separate iron filings from sand because the property of attraction is different for each substance.

Answer

Brief Explanations:

The first sentence refers to the physical separation of solids based on particle size. A sieve allows smaller particles (sesame seeds) to pass through while retaining larger ones (sunflower seeds). Therefore, the physical property that differs is size, and the tool used is a sieve. The second sentence refers to magnetic separation. Iron is a ferromagnetic material, whereas sand is not. A magnet can be used to attract the iron filings, separating them from the non-magnetic sand. The property involved is magnetic attraction.

Answer:

  1. sizes; sieve
  2. magnetic; magnet
