Carrie has a container that contains thousands of mixed glass beads and iron beads of different shapes and sizes.

Which of the following is the best way to separate them?

• The glass beads will float, so she could add water to the container and the glass will float to the top.

• The iron beads are magnetic, so she could separate the glass from the iron with a strong magnet.

• The iron beads might be heavier, so she could shake the container until the iron beads settle to the bottom.

• The iron beads are smaller, so she could pour the beads through a strainer and the glass beads will separate.
