3. Carlos has a container that contains thousands of mixed glass beads, iron beads, and foam beads of
different shapes and sizes. Which of the following is the best way to separate them?
A. The glass and foam beads will float, so she could add water to the container and the glass and
foam will float to the top. The iron beads will sink.
B. The iron beads are magnetic, so she could separate the glass from the iron with a strong
magnet. The foam beads will float to the top and the glass will sink.
C. The iron beads might be heavier, so she could shake the container until the iron beads settle to
the bottom. The glass and foam will float to the top.
D. The iron beads are smaller, so she could pour the beads through a strainer and the glass beads
will separate. The foam will sink to the bottom.
