Students will read an article
about Marie Curie, a Polish-born
French scientist, and her
contributions to the fields of
chemistry and physics. They will
learn about how she overcame
prejudice and discrimination in
the male-dominated world of
science.

Students will add a
picture/biography of Robert
Boyle and Marie Curie to our
wall of famous scientists.
Students make a saturated
solution by adding salt to
water until no more salt will
dissolve. Using a balance,
they find the mass of the
solution to determine the
amount of salt that dissolved
in the solution.
