I enjoyed teaching Light and Shadow in
elementary school. Here are some of the things
from my notes:
1. What is a shadow? The shady
area made by something that has light shining on
2. Students hold their pencils vertically
on their desks, and I ask, "which side of the
pencil will the shadow be on?" Then I turn on the
light - probably a spotlight or a lamp without a

on each of the 4 tables in the science room, plus
several objects (below). I asked them to draw the

near the light and far away (I had a bunch of
plastic H's, like little pieces of I-beams, that I
got from something like a swap meet.)

4. I gave them the 2 hand-outs that
are attached (this was before computers!). The one
with the H's is only useful as an idea, since the
H's aren't readily available.

Regarding your other questions:
I like this poster on Women in Science and Math
from the National Women's History Project:
I don't know where your school is located, so that
affects who might come to give presentations. As
you can see, my science materials, from teaching
at IV school, were fairly simple. Your students
can certainly ask questions over the Internet. I
don't have any particular ideas about pictures of
scientists or careers. I think just talking about
the possibility of being a scientist is enough

for your question, and good luck with your
teaching. Science teaching is so important.
