While we were studying outer space I introduced the
overhead projector for the first time this school year.
A family lent me the blue mesh to hang over the area
and I used a frame from a pop up house to hold it away
from the wall.
The frame is just the right size for the children to go inside and open
enough for a grown up to be involved.
A few things we used were constellation pictures and mesh stars.
Then I added coloured plexi-glass stars, coloured circles and
stir sticks with see through tops.
These two boys discovered that they could turn off the projection on
the wall by lifting and closing the top flap.
They experimented with it and was able to move the light from the floor
and up the wall and back to off.
And there was also interest in the mesh.
