will complete a homework

Venn diagram to show the
differences of each theory. They
can refer to their text if they
need to.
The students will be making a

Students will
determine:
Elements are
arranged in order of
increasing atomic
number.
Students use paint on PC in the
computer lab to illustrate their
own “Atom”. Students should
then be told to check the name
of the element they made and
label all parts. An alternative to
this assignment is to make the
youtube video using
www.animoto.com of their
completed 3D atom. This will
be suggested if the students can
do as part of computer class for
the sake of time.
Students will complete and
upload their video and share it.
