Our light exploration began with exploring with flash lights
and mirrors. The children first used the flash light by waving the flash
light around the room.
"Look an apple." After observing how the light
moves the children sat down and shined the light on the floor. They noticed how
the light made different shapes.
They
then picked up the mirrors and shined the light off the surface. They notice
how the light reflected off the surface of the mirror.
Next the children selected different objects from the
classroom and shined the light on them. They discovered how the light made the
objects appearance change. They noticed how the light made the objects bigger
and smaller. To extend the children's investigation we are going explore how
light affects the size of objects.
For our second exploration we used the projector and
different size blocks. The children placed each block on the projector and
observed the different sizes.
The children compare the sizes between the original object
and the shadow the children by holding up the block next to the shadow.
To better understand the concept of measuring we traced the
shadow and then compared its size to the block.
By moving the projector back and forth the children were
able to determine the cause of the shadows change. They noticed the shadow was
smaller when the projector was closer to the wall. When the projector was moved
father away they noticed the shadow was bigger.
Our next investigation we will be using the shadow screen to
watch how the light affects our shadows appearance.
